Quick answer
To improve your readability score, reduce average sentence length, replace unnecessarily complex words, use active voice and break dense paragraphs into clear sections.
Make the writing easier to follow, not just easier to score. A higher score is useful only if the text still says what it needs to say.

How readability scores work
Most readability formulas look at sentence length and word complexity. The Calculatorz checker uses Flesch Reading Ease, which rewards shorter sentences and words with fewer syllables.
Flesch Reading Ease =
206.835 - 1.015 × (words ÷ sentences)
- 84.6 × (syllables ÷ words)This means two things matter a lot: how many words are in the average sentence, and how complex the average word is. Improving either can improve the score.
Step 1: Shorten long sentences
Long sentences are one of the biggest reasons readability scores fall. A sentence can be grammatically correct but still hard to read if it carries too many ideas.
If a sentence has more than one main point, split it. If it has multiple commas, brackets or “and” clauses, check whether it is trying to do too much.

It helps you see whether your copy may feel easy or difficult to read. | The same idea is split into two clearer sentences. |
| When users are working to strict limits, they should check the count regularly because leaving it until the end can make editing harder. | Check the count as you write. Waiting until the end can make editing harder. | The advice becomes more direct and easier to act on. |
Step 2: Replace complex words where simpler words work
Complex words are not always bad. Technical terms, legal terms and specialist language may be necessary. The problem is using difficult wording when a simpler word would say the same thing.
| Harder wording | Clearer wording |
|---|---|
| Utilise | Use |
| Demonstrate | Show |
| Approximately | About |
| Additional | More |
| Commence | Start |
| Subsequently | Then |
Do not remove precise words just to increase the score. If a specialist term is the accurate term, keep it and explain it clearly.
Step 3: Use active voice
Active voice usually makes writing shorter and easier to understand because the reader can see who is doing what.
The form was completed by the applicant before the deadline.
The applicant completed the form before the deadline.
Passive voice is not always wrong. It can be useful when the action matters more than the person doing it. But if your writing feels slow, check for sentences that hide the subject.
Step 4: Break up dense paragraphs
Readability formulas mostly score words and sentences, but real readers also care about layout. A paragraph can have a decent score and still feel heavy if it is too dense.
- Keep one main idea per paragraph.
- Use headings to signal what each section covers.
- Use bullet points when the reader needs to scan options or steps.
- Put the main answer before the explanation.
- Use examples after the rule, not before it.
For web copy especially, structure can matter as much as sentence length.
Step 5: Remove filler and throat-clearing
Many drafts start with phrases that delay the main point. Removing them improves both readability and word count.
| Remove or shorten | Better option |

Trying to cut words too?
The same edits often improve readability and reduce word count at the same time.
What score should you aim for?
There is no perfect readability score. The right score depends on audience, topic and purpose. A page for the general public should usually be easier than a technical manual or academic essay.
| Writing type | Practical readability aim | What to watch |
|---|---|---|
| General web content | Clear, direct and easy to scan | Long intros, vague wording and dense sections. |
| Applications and personal statements | Clear but still specific and credible | Cutting too much detail or sounding too generic. |
| Technical content | Clear explanations with necessary terms | Replacing precise terms with vague ones. |
| Academic writing | Structured and readable, not oversimplified | Removing nuance just to increase the score. |
Before and after readability edit
Due to the fact that many users are required to submit written answers within strict limits, it is important to ensure that the content is concise, clear and not unnecessarily complicated.
Many users must submit answers within strict limits. The writing should be clear, concise and simple to follow.
The edited version is shorter, more direct and easier to read. It keeps the meaning but removes filler, splits the sentence and replaces heavier phrasing.
A simple readability improvement workflow
- Paste your draft into the Readability Score Checker.
- Check the average sentence length.
- Split the longest sentences first.
- Replace complex words only where simpler words keep the same meaning.
- Remove filler phrases and repeated points.
- Break dense paragraphs into clearer sections.
- Check the score again.
- Read the final text yourself to make sure it still sounds right.
You can also use the Word Counter to track sentence count, paragraphs and reading time while editing.
Common readability mistakes
- Chasing the score too hard: a high score does not prove the writing is useful.
- Cutting necessary detail: some topics need context, examples and precise terms.
- Making every sentence short: a mix of sentence lengths often reads better.
- Ignoring structure: headings, paragraphs and bullet points affect real readability too.
- Using vague simple words: simple wording should still be specific.
Readability score improvement FAQs
What is the fastest way to improve a readability score?
Split long sentences and replace unnecessarily complex words. These two changes usually affect readability formulas the most.
Should every sentence be short?
No. Very short sentences can sound choppy. Aim for clarity and variety rather than making every sentence the same length.
Is a higher readability score always better?
No. A higher score is usually useful for general readers, but specialist writing may need terms that reduce the score while improving accuracy.
Can I improve readability without reducing word count?
Yes. You can improve readability by splitting sentences, adding headings, using clearer structure and explaining difficult terms.
