How do you structure a paragraph in an essay?

If you’re like the majority of my students, you might be getting your basic essay paragraph structure wrong and getting lower grades than you could!

In this article, I outline the 11 key steps to writing a perfect paragraph. But, this isn’t your normal ‘how to write an essay’ article. Rather, I’ll try to give you some insight into exactly what teachers look out for when they’re grading essays and figuring out what grade to give them.

You can navigate each issue below, or scroll down to read them all:

1. Paragraphs must be at least four sentences long 2. But, at most seven sentences long 3. Your paragraph must be Left-Aligned 4. You need a topic sentence 5 . Next, you need an explanation sentence 6. You need to include an example 7. You need to include citations 8. All paragraphs need to be relevant to the marking criteria 9. Only include one key idea per paragraph 10. Keep sentences short 11. Keep quotes short

Paragraph structure is one of the most important elements of getting essay writing right .

As I cover in my Ultimate Guide to Writing an Essay Plan , paragraphs are the heart and soul of your essay.

However, I find most of my students have either:

• forgotten how to write paragraphs properly,
• gotten lazy, or
• never learned it in the first place!

Paragraphs in essay writing are different from paragraphs in other written genres .

In fact, the paragraphs that you are reading now would not help your grades in an essay.

That’s because I’m writing in journalistic style, where paragraph conventions are vastly different.

For those of you coming from journalism or creative writing, you might find you need to re-learn paragraph writing if you want to write well-structured essay paragraphs to get top grades.

Below are eleven reasons your paragraphs are losing marks, and what to do about it!

Essay Paragraph Structure Rules

1. your paragraphs must be at least 4 sentences long.

In journalism and blog writing, a one-sentence paragraph is great. It’s short, to-the-point, and helps guide your reader. For essay paragraph structure, one-sentence paragraphs suck.

A one-sentence essay paragraph sends an instant signal to your teacher that you don’t have much to say on an issue.

A short paragraph signifies that you know something – but not much about it. A one-sentence paragraph lacks detail, depth and insight.

Many students come to me and ask, “what does ‘add depth’ mean?” It’s one of the most common pieces of feedback you’ll see written on the margins of your essay.

Personally, I think ‘add depth’ is bad feedback because it’s a short and vague comment. But, here’s what it means: You’ve not explained your point enough!

If you’re writing one-, two- or three-sentence essay paragraphs, you’re costing yourself marks.

Always aim for at least four sentences per paragraph in your essays.

This doesn’t mean that you should add ‘fluff’ or ‘padding’ sentences.

Make sure you don’t:

a) repeat what you said in different words, or b) write something just because you need another sentence in there.

But, you need to do some research and find something insightful to add to that two-sentence paragraph if you want to ace your essay.

Check out Points 5 and 6 for some advice on what to add to that short paragraph to add ‘depth’ to your paragraph and start moving to the top of the class.

2. Your Paragraphs must not be more than 7 Sentences Long

Okay, so I just told you to aim for at least four sentences per paragraph. So, what’s the longest your paragraph should be?

Seven sentences. That’s a maximum.

So, here’s the rule:

Between four and seven sentences is the sweet spot that you need to aim for in every single paragraph.

Here’s why your paragraphs shouldn’t be longer than seven sentences:

1. It shows you can organize your thoughts. You need to show your teacher that you’ve broken up your key ideas into manageable segments of text (see point 10)

2. It makes your work easier to read.   You need your writing to be easily readable to make it easy for your teacher to give you good grades. Make your essay easy to read and you’ll get higher marks every time.

One of the most important ways you can make your work easier to read is by writing paragraphs that are less than six sentences long.

3. It prevents teacher frustration. Teachers are just like you. When they see a big block of text their eyes glaze over. They get frustrated, lost, their mind wanders … and you lose marks.

To prevent teacher frustration, you need to ensure there’s plenty of white space in your essay. It’s about showing them that the piece is clearly structured into one key idea per ‘chunk’ of text.

Often, you might find that your writing contains tautologies and other turns of phrase that can be shortened for clarity.

3. Your Paragraph must be Left-Aligned

Turn off ‘Justified’ text and: Never. Turn. It. On. Again.

Justified text is where the words are stretched out to make the paragraph look like a square. It turns the writing into a block. Don’t do it. You will lose marks, I promise you! Win the psychological game with your teacher: left-align your text.

A good essay paragraph is never ‘justified’.

I’m going to repeat this, because it’s important: to prevent your essay from looking like a big block of muddy, hard-to-read text align your text to the left margin only.

You want white space on your page – and lots of it. White space helps your reader scan through your work. It also prevents it from looking like big blocks of text.

You want your reader reading vertically as much as possible: scanning, browsing, and quickly looking through for evidence you’ve engaged with the big ideas.

The justified text doesn’t help you do that. Justified text makes your writing look like a big, lumpy block of text that your reader doesn’t want to read.

What’s wrong with Center-Aligned Text?

While I’m at it, never, ever, center-align your text either. Center-aligned text is impossible to skim-read. Your teacher wants to be able to quickly scan down the left margin to get the headline information in your paragraph.

Not many people center-align text, but it’s worth repeating: never, ever center-align your essays.

Don’t annoy your reader. Left align your text.

4. Your paragraphs must have a Topic Sentence

The first sentence of an essay paragraph is called the topic sentence. This is one of the most important sentences in the correct essay paragraph structure style.

The topic sentence should convey exactly what key idea you’re going to cover in your paragraph.

Too often, students don’t let their reader know what the key idea of the paragraph is until several sentences in.

You must show what the paragraph is about in the first sentence.

You never, ever want to keep your reader in suspense. Essays are not like creative writing. Tell them straight away what the paragraph is about. In fact, if you can, do it in the first half of the first sentence .

I’ll remind you again: make it easy to grade your work. Your teacher is reading through your work trying to determine what grade to give you. They’re probably going to mark 20 assignments in one sitting. They have no interest in storytelling or creativity. They just want to know how much you know! State what the paragraph is about immediately and move on.

Suggested: Best Words to Start a Paragraph

Ideal Essay Paragraph Structure Example: Writing a Topic Sentence If your paragraph is about how climate change is endangering polar bears, say it immediately : “Climate change is endangering polar bears.” should be your first sentence in your paragraph. Take a look at first sentence of each of the four paragraphs above this one. You can see from the first sentence of each paragraph that the paragraphs discuss:

When editing your work, read each paragraph and try to distil what the one key idea is in your paragraph. Ensure that this key idea is mentioned in the first sentence .

(Note: if there’s more than one key idea in the paragraph, you may have a problem. See Point 9 below .)

The topic sentence is the most important sentence for getting your essay paragraph structure right. So, get your topic sentences right and you’re on the right track to a good essay paragraph.

5. You need an Explanation Sentence

All topic sentences need a follow-up explanation. The very first point on this page was that too often students write paragraphs that are too short. To add what is called ‘depth’ to a paragraph, you can come up with two types of follow-up sentences: explanations and examples.

Let’s take explanation sentences first.

Explanation sentences give additional detail. They often provide one of the following services:

Let’s go back to our example of a paragraph on Climate change endangering polar bears. If your topic sentence is “Climate change is endangering polar bears.”, then your follow-up explanation sentence is likely to explain how, why, where, or when. You could say:

Ideal Essay Paragraph Structure Example: Writing Explanation Sentences 1. How: “The warming atmosphere is melting the polar ice caps.” 2. Why: “The polar bears’ habitats are shrinking every single year.” 3. Where: “This is happening in the Antarctic ice caps near Greenland.” 4. When: “Scientists first noticed the ice caps were shrinking in 1978.”

You don’t have to provide all four of these options each time.

But, if you’re struggling to think of what to add to your paragraph to add depth, consider one of these four options for a good quality explanation sentence.

6. Your need to Include an Example

Examples matter! They add detail. They also help to show that you genuinely understand the issue. They show that you don’t just understand a concept in the abstract; you also understand how things work in real life.

Example sentences have the added benefit of personalising an issue. For example, after saying “Polar bears’ habitats are shrinking”, you could note specific habitats, facts and figures, or even a specific story about a bear who was impacted.

Ideal Essay Paragraph Structure Example: Writing an ‘Example’ Sentence “For example, 770,000 square miles of Arctic Sea Ice has melted in the past four decades, leading Polar Bear populations to dwindle ( National Geographic, 2018 )

In fact, one of the most effective politicians of our times – Barrack Obama – was an expert at this technique. He would often provide examples of people who got sick because they didn’t have healthcare to sell Obamacare.

What effect did this have? It showed the real-world impact of his ideas. It humanised him, and got him elected president – twice!

Be like Obama. Provide examples. Often.

7. All Paragraphs need Citations

Provide a reference to an academic source in every single body paragraph in the essay. The only two paragraphs where you don’t need a reference is the introduction and conclusion .

Let me repeat: Paragraphs need at least one reference to a quality scholarly source .

Let me go even further:

Students who get the best marks provide two references to two different academic sources in every paragraph.

Two references in a paragraph show you’ve read widely, cross-checked your sources, and given the paragraph real thought.

It’s really important that these references link to academic sources, not random websites, blogs or YouTube videos. Check out our Seven Best types of Sources to Cite in Essays post to get advice on what sources to cite. Number 6 w ill surprise you!

Ideal Essay Paragraph Structure Example: In-Text Referencing in Paragraphs Usually, in-text referencing takes the format: (Author, YEAR), but check your school’s referencing formatting requirements carefully. The ‘Author’ section is the author’s last name only. Not their initials. Not their first name. Just their last name . My name is Chris Drew. First name Chris, last name Drew. If you were going to reference an academic article I wrote in 2019, you would reference it like this: (Drew, 2019).

Where do you place those two references?

Place the first reference at the end of the first half of the paragraph. Place the second reference at the end of the second half of the paragraph.

This spreads the references out and makes it look like all the points throughout the paragraph are backed up by your sources. The goal is to make it look like you’ve reference regularly when your teacher scans through your work.

Remember, teachers can look out for signposts that indicate you’ve followed academic conventions and mentioned the right key ideas.

Spreading your referencing through the paragraph helps to make it look like you’ve followed the academic convention of referencing sources regularly.

Here are some examples of how to reference twice in a paragraph:

• If your paragraph was six sentences long, you would place your first reference at the end of the third sentence and your second reference at the end of the sixth sentence.
• If your paragraph was five sentences long, I would recommend placing one at the end of the second sentence and one at the end of the fifth sentence.

You’ve just read one of the key secrets to winning top marks.

8. Every Paragraph must be relevant to the Marking Criteria

Every paragraph must win you marks. When you’re editing your work, check through the piece to see if every paragraph is relevant to the marking criteria.

For the British: In the British university system (I’m including Australia and New Zealand here – I’ve taught at universities in all three countries), you’ll usually have a ‘marking criteria’. It’s usually a list of between two and six key learning outcomes your teacher needs to use to come up with your score. Sometimes it’s called a:

• Marking criteria
• Marking rubric
• (Key) learning outcome
• Indicative content

Check your assignment guidance to see if this is present. If so, use this list of learning outcomes to guide what you write. If your paragraphs are irrelevant to these key points, delete the paragraph .

Paragraphs that don’t link to the marking criteria are pointless. They won’t win you marks.

For the Americans: If you don’t have a marking criteria / rubric / outcomes list, you’ll need to stick closely to the essay question or topic. This goes out to those of you in the North American system. North America (including USA and Canada here) is often less structured and the professor might just give you a topic to base your essay on.

If all you’ve got is the essay question / topic, go through each paragraph and make sure each paragraph is relevant to the topic.

For example, if your essay question / topic is on “The Effects of Climate Change on Polar Bears”,

• Don’t talk about anything that doesn’t have some connection to climate change and polar bears;
• Don’t talk about the environmental impact of oil spills in the Gulf of Carpentaria;
• Don’t talk about black bear habitats in British Columbia.
• Do talk about the effects of climate change on polar bears (and relevant related topics) in every single paragraph .

You may think ‘stay relevant’ is obvious advice, but at least 20% of all essays I mark go off on tangents and waste words.

Stay on topic in Every. Single. Paragraph. If you want to learn more about how to stay on topic, check out our essay planning guide .

9. Only have one Key Idea per Paragraph

One key idea for each paragraph. One key idea for each paragraph. One key idea for each paragraph.

Don’t forget!

Too often, a student starts a paragraph talking about one thing and ends it talking about something totally different. Don’t be that student.

To ensure you’re focussing on one key idea in your paragraph, make sure you know what that key idea is. It should be mentioned in your topic sentence (see Point 3 ). Every other sentence in the paragraph adds depth to that one key idea.

If you’ve got sentences in your paragraph that are not relevant to the key idea in the paragraph, they don’t fit. They belong in another paragraph.

Go through all your paragraphs when editing your work and check to see if you’ve veered away from your paragraph’s key idea. If so, you might have two or even three key ideas in the one paragraph.

You’re going to have to get those additional key ideas, rip them out, and give them paragraphs of their own.

If you have more than one key idea in a paragraph you will lose marks. I promise you that.

The paragraphs will be too hard to read, your reader will get bogged down reading rather than scanning, and you’ll have lost grades.

10. Keep Sentences Short

If a sentence is too long it gets confusing. When the sentence is confusing, your reader will stop reading your work. They will stop reading the paragraph and move to the next one. They’ll have given up on your paragraph.

Short, snappy sentences are best.

Shorter sentences are easier to read and they make more sense. Too often, students think they have to use big, long, academic words to get the best marks. Wrong. Aim for clarity in every sentence in the paragraph. Your teacher will thank you for it.

The students who get the best marks write clear, short sentences.

When editing your draft, go through your essay and see if you can shorten your longest five sentences.

(To learn more about how to write the best quality sentences, see our page on Seven ways to Write Amazing Sentences .)

11. Keep Quotes Short

Eighty percent of university teachers hate quotes. That’s not an official figure. It’s my guestimate based on my many interactions in faculty lounges. Twenty percent don’t mind them, but chances are your teacher is one of the eight out of ten who hate quotes.

Teachers tend to be turned off by quotes because it makes it look like you don’t know how to say something on your own words.

Now that I’ve warned you, here’s how to use quotes properly:

Ideal Essay Paragraph Structure Example: How To Use Quotes in University-Level Essay Paragraphs 1. Your quote should be less than one sentence long. 2. Your quote should be less than one sentence long. 3. You should never start a sentence with a quote. 4. You should never end a paragraph with a quote. 5 . You should never use more than five quotes per essay. 6. Your quote should never be longer than one line in a paragraph.

The minute your teacher sees that your quote takes up a large chunk of your paragraph, you’ll have lost marks.

Your teacher will circle the quote, write a snarky comment in the margin, and not even bother to give you points for the key idea in the paragraph.

Avoid quotes, but if you really want to use them, follow those five rules above.

I’ve also provided additional pages outlining Seven tips on how to use Quotes if you want to delve deeper into how, when and where to use quotes in essays. Be warned: quoting in essays is harder than you thought.

Follow the advice above and you’ll be well on your way to getting top marks at university.

Hello there. I noticed that throughout this article on Essay Writing, you keep on saying that the teacher won’t have time to go through the entire essay. Don’t you think this is a bit discouraging that with all the hard work and time put into your writing, to know that the teacher will not read through the entire paper?

Hi Clarence,

Thanks so much for your comment! I love to hear from readers on their thoughts.

Yes, I agree that it’s incredibly disheartening.

But, I also think students would appreciate hearing the truth.

Behind closed doors many / most university teachers are very open about the fact they ‘only have time to skim-read papers’. They regularly bring this up during heated faculty meetings about contract negotiations! I.e. in one university I worked at, we were allocated 45 minutes per 10,000 words – that’s just over 4 minutes per 1,000 word essay, and that’d include writing the feedback, too!

If students know the truth, they can better write their essays in a way that will get across the key points even from a ‘skim-read’.

I hope to write candidly on this website – i.e. some of this info will never be written on university blogs because universities want to hide these unfortunate truths from students.

Thanks so much for stopping by!

Regards, Chris

This is wonderful and helpful, all I say is thank you very much. Because I learned a lot from this site, own by chris thank you Sir.

Thank you. This helped a lot.

Daily Writing Tips

How long should a paragraph be.

A paragraph should consist of six to seven sentences. No, it should be no longer than three sentences long. Actually, it should include a topic sentence, several supporting sentences, and possibly a concluding sentence. Sigh. Can I end this paragraph yet?

All three of the declarations in the previous paragraph (the first pair of which come, respectively, from sources within Purdue University and Stanford University, two of the most prestigious institutions of higher learning in the United States), and any similarly quantitative statements, are wrong. The correct answer is that a paragraph has to be long enough to reach its end.

Like this one.

A paragraph can be as long or as short as you want it to be. It can unfold for countless pages or consist of one word — even one letter.

(I meant to write, “Wait!” but was interrupted.)

The determination to make in composing a given paragraph is not the number of sentences or words or letters, but the number of ideas. The rule of thumb — in nonfiction, at least — is that each paragraph should focus on one idea or concept; when you shift to a new idea, shift to a new paragraph. (In fiction, its function is more nebulous: A paragraph is a unit of writing that further develops a story through exposition.)

However, ideas, as we all know, are slippery things, difficult to package and unlikely to remain in their allotted places. How big or small is an idea? What about an idea within an idea?

Ultimately, a paragraph is complete when you decide it is.

Where, then, did the various judgments of proper paragraph length come from? They result from well-intentioned but misguided efforts of educators to help students learn the fundamentals of writing.

The topic-support-conclusion model (one variation of which is named the Schaffer paragraph, after its developer, Jane Schaffer) is valid in that it helps developing writers discipline themselves to craft effective persuasive arguments. Opinions easily dissipate if they are not backed up by facts or reasoning. But the form is only that — a mold that can (and should) be broken once a writer learns how to use it.

And dictating that a paragraph consist of a given number of sentences is an understandable but lazy approach that ensures that student writers provide details before moving on to the next idea but does not teach them why they must hit the number — much like requiring a word count for an essay or report ensures that most students will focus on grasping for quantity rather than striving for quality.

There are, of course, practical considerations in determining paragraph length. Readers of newspapers and other print publications with narrow columns of text are more likely to read paragraphs that don’t extend vertically more than a couple of inches. Similarly, websites are easier to read when paragraphs are brief. Care should be taken, likewise, in book manuscripts to avoid paragraphs that extend for more than half a page.

My rule of thumb in editing is, when working in a Microsoft Word file, to break up paragraphs of more than ten lines in 12-point type with a six-inch column width for print publications and to limit online copy to five lines (as I’ve done here), though results will of course vary depending on the point size and column width of the particular text.

Don’t hesitate to adhere to or promote specific models of paragraph construction, but be sure that the teaching or learning involved emphasizes the versatility of the paragraph form.

12 thoughts on “How Long Should a Paragraph Be?”

Good stuff Mark. Since I’m a fiction writer, I generally try to keep my paragraphs to one development unit. But sometimes it’s a bit difficult to identify what defines a development unit. When I’m blogging, my paragraphs are normally 2 sentences to ease the reading just like you mentioned.

Great article! Can I use this with my composition students? Thanks!

LOL … yep, a paragraph’s as long as it needs to be … also, 42

Good article, Mike.

Style Guides can be useful, but often seem to lack common sense – your post offers a useful antidote!

The points regarding paragraphs are approximates those I follow while writing articles and blogs writing. Now I fee I’ right to make them even shorter.

Big paragraphs scare away readers at the first glimpse, let alone read them.

Thanks for the informative write-up.

Luckily, I was never told in school, or anywhere, how long a paragraph should be. It sounds crazy!

I agree, but when teaching academic writing to non-nativespeakers, the topic-highlighting-concluding structure works well because they often do not have a feel for where a paragraph should logically come to an end.

Academic writing needs to be very structured in order to convey complex ideas in a readable fashion. I would be much more flexible about paragraph length in business writing and narrative writing. After all, we all know the one line paragraph can have tremendous effect.

It’s all about audience and purpose.

Re: Vallypee

It’s all about audience, media, and purpose?

Thank you for this! Honestly, every teacher has different ideas on this subject, but my current english teacher has taught nothing on how long they feel it should be. I have a paragraph that is a page long, and was just wondering if it was too long!

I’ve actually come across someone who used too short paragraphs.

He/she used a new paragraph almost every sentence, regardless how short.

It didn’t make the text easier to read.

And the paragraphs didn’t seem to have much purpose, since every sentence was a new one anyways.

I think that a paragraph should be at least 75 words or more. I am in my honors english class (9th grade honors) and I just googled how many words in a paragraph, and did not see anything, so I am just estimating and sharing.

I just wanted to say that this was a great, and, “very”, much needed piece. I believe everyone has diffrent questions about diffrent writing topics, due to learning from so many sources throughout our lives, that it’s very important that there not only be a frame of reference, but a clear, and concise one.

I believe technology, (texting, spell check, the internet, etc.), have both been a blessing, and a curse, because it has made our lives so much more convenient, productive, (for most), as well as interesting, while also having the negative effect of attention span, communication, to much multitasking, and an everly increasing, negative erosion, of language. With the rise of slang, “text speech”, short hand, language barriers, and so many other things, basic writing principles have been disappearing, and or forgotten.

I can only speak for myself, on this one, but I have found that, “spell check”, has given my spelling a terrible beating, and I often find myself having issue spelling a lot of words if not for spell check. I have actually madea practice of only using it when in a hurry, or in a bind.

Of course I am not near the caliber of most others in these comments, (writers, teachers, etc.), or even the author of this piece, himself being an editor, but it is reassuring, and wonderful to know that these types of sites, and information, are available when in need, and as a learning tool. I did want to tip my hat to the author of this piece/site, and his ability to explain things fully, correctly, consise, and to the point without making the subject a legnthy burden to learn, or use as just a refresher, (sometimes a person comes away with more quetions, then when they began their search), but gladly this is not such a place, thank you.

What is a paragraph?

A paragraph is a collection of related sentences dealing with a single topic. Learning to write good paragraphs will help you as a writer stay on track during your drafting and revision stages. Good paragraphing also greatly assists your readers in following a piece of writing. You can have fantastic ideas, but if those ideas aren't presented in an organized fashion, you will lose your readers (and fail to achieve your goals in writing).

The Basic Rule: Keep one idea to one paragraph

The basic rule of thumb with paragraphing is to keep one idea to one paragraph. If you begin to transition into a new idea, it belongs in a new paragraph. There are some simple ways to tell if you are on the same topic or a new one. You can have one idea and several bits of supporting evidence within a single paragraph. You can also have several points in a single paragraph as long as they relate to the overall topic of the paragraph. If the single points start to get long, then perhaps elaborating on each of them and placing them in their own paragraphs is the route to go.

Elements of a paragraph

To be as effective as possible, a paragraph should contain each of the following: Unity, Coherence, A Topic Sentence, and Adequate Development. As you will see, all of these traits overlap. Using and adapting them to your individual purposes will help you construct effective paragraphs.

The entire paragraph should concern itself with a single focus. If it begins with one focus or major point of discussion, it should not end with another or wander within different ideas.

Coherence is the trait that makes the paragraph easily understandable to a reader. You can help create coherence in your paragraphs by creating logical bridges and verbal bridges.

Logical bridges

• The same idea of a topic is carried over from sentence to sentence
• Successive sentences can be constructed in parallel form

Verbal bridges

• Key words can be repeated in several sentences
• Synonymous words can be repeated in several sentences
• Pronouns can refer to nouns in previous sentences
• Transition words can be used to link ideas from different sentences

A topic sentence

A topic sentence is a sentence that indicates in a general way what idea or thesis the paragraph is going to deal with. Although not all paragraphs have clear-cut topic sentences, and despite the fact that topic sentences can occur anywhere in the paragraph (as the first sentence, the last sentence, or somewhere in the middle), an easy way to make sure your reader understands the topic of the paragraph is to put your topic sentence near the beginning of the paragraph. (This is a good general rule for less experienced writers, although it is not the only way to do it). Regardless of whether you include an explicit topic sentence or not, you should be able to easily summarize what the paragraph is about.

Adequate development

The topic (which is introduced by the topic sentence) should be discussed fully and adequately. Again, this varies from paragraph to paragraph, depending on the author's purpose, but writers should be wary of paragraphs that only have two or three sentences. It's a pretty good bet that the paragraph is not fully developed if it is that short.

Some methods to make sure your paragraph is well-developed:

• Use examples and illustrations
• Cite data (facts, statistics, evidence, details, and others)
• Examine testimony (what other people say such as quotes and paraphrases)
• Use an anecdote or story
• Define terms in the paragraph
• Compare and contrast
• Evaluate causes and reasons
• Examine effects and consequences
• Analyze the topic
• Describe the topic
• Offer a chronology of an event (time segments)

How do I know when to start a new paragraph?

You should start a new paragraph when:

• When you begin a new idea or point. New ideas should always start in new paragraphs. If you have an extended idea that spans multiple paragraphs, each new point within that idea should have its own paragraph.
• To contrast information or ideas. Separate paragraphs can serve to contrast sides in a debate, different points in an argument, or any other difference.
• When your readers need a pause. Breaks between paragraphs function as a short "break" for your readers—adding these in will help your writing be more readable. You would create a break if the paragraph becomes too long or the material is complex.
• When you are ending your introduction or starting your conclusion. Your introductory and concluding material should always be in a new paragraph. Many introductions and conclusions have multiple paragraphs depending on their content, length, and the writer's purpose.

Transitions and signposts

Two very important elements of paragraphing are signposts and transitions. Signposts are internal aids to assist readers; they usually consist of several sentences or a paragraph outlining what the article has covered and where the article will be going.

Transitions are usually one or several sentences that "transition" from one idea to the next. Transitions can be used at the end of most paragraphs to help the paragraphs flow one into the next.
