How to improve readability
Five fixes, ordered by how much they typically move the score.
- 1
Split sentences over 25 words
Every sentence longer than 25 words drags the Flesch score down. Break it in two.
- 2
Swap 3-syllable+ words
Prefer “use” over “utilize”, “help” over “facilitate”. Syllables per word is half of the Flesch formula.
- 3
Cut passive voice
Rewrite “was written by the team” as “the team wrote it”. Active reads faster.
- 4
Break dense paragraphs
Cap paragraphs at 3–5 sentences so mobile readers can scan.
- 5
Remove fillers
Delete “very”, “really”, “just”, “basically”. They add length without meaning.
