One idea per paragraph helps users absorb information. Organise them under headings to help users scan the content. Write short paragraphs, each with a topic sentence.
Limit each paragraph to one idea
People find it easier to understand content when a paragraph contains only one idea or theme. Don’t introduce a new idea in the middle or at the end of a paragraph. Start a new paragraph instead.
Introduction or summary paragraphs recap ideas covered in the content. Group sentences in these paragraphs by theme – for example, to help users understand how the content is structured.
Put paragraphs in the order that makes sense to the user
Order paragraphs in a logical sequence, such as:
- steps in a transaction
- the order of importance
- cause then effect
- problem then solution
- pros then cons.
This helps people follow related ideas or steps in a sequence.
Expand on the heading in the first paragraph
The first paragraph under a heading helps people decide if they’ve found the information they need. Search engines also use first paragraphs when analysing content.
Use the first paragraph to make the purpose of your content easier to find in searches. It should include a topic sentence and summarise the following paragraphs.
You can use first paragraphs to improve long-form content, such as reports. First paragraphs can summarise the main points in each section.
Copy and paste all the first paragraphs together to compile a summary of your content. If you’re missing any main points, rewrite some of your first paragraphs.
Keep most paragraphs to 2 or 3 sentences
Short paragraphs help people understand content. The ideal length depends on what you are writing:
- Media releases and news articles have only one or 2 sentences in a paragraph.
- Content designed for mobile screens has no more than 2 or 3 sentences in a paragraph.
- In reports and other long-form content, a limit of 6 sentences in a paragraph is acceptable.
If your paragraphs or sentences are too long, you might be trying to say too much in one place.
Consider starting a new paragraph or using an itemised list. Make sure the items relate to each other and are grammatically parallel.
Digital Service Standard requirements
Use responsive design methods to make sure users can read the content on any device. Short paragraphs are critical in responsive design: Criterion 6. Consistent and responsive design.
Many people do not use a desktop computer or printed material to access government services and information. Test your content on a mobile device first.
Write clear sentences using fewer than 25 words
All sentences should use plain language. Even in technical documents, keep sentences to fewer than 25 words. Long sentences often cause long paragraphs.
Sentences in a paragraph develop the main idea from a topic sentence by:
- giving examples or details
- comparing or contrasting
- showing cause and effect
- drawing conclusions from evidence.
In complex content, you might need to use a paragraph or more for each of these points.
Introduce the main idea in the topic sentence
The first sentence in each paragraph should be the topic sentence. The topic sentence helps people follow the meaning of your writing as they skim content.
Each paragraph should contain only the information that relates to the topic sentence.
Our rapid response team began operating in 2019 as a result of the 2018 stakeholder survey. The survey showed it took too long to repair damage.
A stakeholder survey in 2018 revealed dissatisfaction with the time taken to repair damage. Our rapid response team began operating in 2019.
[This paragraph is about the rapid response team, not the stakeholder survey. The grammatical subject of the topic sentence should be ‘the team’, not ‘the survey’.]
Remember, users might only read one paragraph. Don’t assume that users will know what ‘it’ or ‘they’ refers to.
The digital edition is based on the material in the sixth edition. It gives more advice on how to put paragraphs together, what belongs in a paragraph and when to start a new one. It fleshes out the advice on topic sentences. It does not give information about numbered paragraphs.
The sixth edition focused on being succinct and on the length of paragraphs.
The digital edition also builds on the Content Guide, which recommended using short, simple paragraphs of 2 or 3 sentences containing one idea.
