Readability

writing metric

01 Definition

Readability meaning: How easily a reader can understand a piece of writing.

Readability describes how easy text is to read and understand, shaped by sentence length, word difficulty, and structure. Writers often check it with formulas that estimate a grade level. Scores are useful guides, not verdicts, since they miss meaning, tone, and how well ideas connect.

Why it matters

How Readability fits the work

Clear, readable copy reaches more people, reduces the effort of understanding, and keeps readers moving through your message instead of giving up.

In context

A health site rewrites a dense paragraph into shorter sentences, raising its readability so patients can follow the instructions without help.

Practical note

Readability formulas count syllables and sentence length, so they can be fooled. Short choppy sentences may score well yet still read poorly, so use judgment too.
