Sentence length and readability
Readability formulas lean heavily on sentence length. Splitting a 40-word sentence into two shorter ones is often the fastest way to make a paragraph easier to scan, especially on mobile screens.
Frequently asked questions
- How does Countly detect a sentence?
- A sentence ends at a full stop, question mark, exclamation mark or ellipsis. Trailing text without punctuation still counts as one sentence.
- What is a good average sentence length?
- Aim for 15–20 words per sentence for web copy. Longer averages usually signal harder-to-read writing.
