    How to improve readability

    Five fixes, ordered by how much they typically move the score.

    1. 1

      Split sentences over 25 words

      Every sentence longer than 25 words drags the Flesch score down. Break it in two.

    2. 2

      Swap 3-syllable+ words

      Prefer “use” over “utilize”, “help” over “facilitate”. Syllables per word is half of the Flesch formula.

    3. 3

      Cut passive voice

      Rewrite “was written by the team” as “the team wrote it”. Active reads faster.

    4. 4

      Break dense paragraphs

      Cap paragraphs at 3–5 sentences so mobile readers can scan.

    5. 5

      Remove fillers

      Delete “very”, “really”, “just”, “basically”. They add length without meaning.
