Reading the Flesch score

Flesch reading ease runs from 0 to 100, and higher means easier. It combines average sentence length with average syllables per word, so a text scores well by having short sentences made of short words.

Score	Band	Roughly
90–100	Very easy	Age 11 and under
80–89	Easy	Popular fiction, tabloid press
70–79	Fairly easy	Consumer web copy
60–69	Plain English	Quality journalism, business writing
50–59	Fairly difficult	Broadsheet features, textbooks
30–49	Difficult	Academic and professional prose
0–29	Very difficult	Legal and technical documents

Most general-audience writing should land between 55 and 70. Public-sector plain-language guidance often asks for 60 or above. Anything under 30 is heavy going for readers outside the field.

What the score cannot see

Readability formulas count syllables and sentence lengths. They cannot read.

Jargon in short words scores well and still baffles the reader. We will sunset the tier is Flesch-friendly and meaningless to an outsider.
Logical order is invisible to the formula. Well-scoring prose in the wrong sequence is still confusing.
Accuracy is not measured at all. A clear sentence can be entirely wrong.
Deliberate difficulty is sometimes correct. Precision in legal or scientific writing is worth a lower score.

Use the score as a flag, not a target. If it drops sharply in one section, that section probably needs work. Optimising the whole document toward a number produces choppy, artificial prose.

Flesch–Kincaid grade level

The same two inputs, arranged to output a US school grade instead of a 0–100 scale. A grade level of 8 means an average American eighth-grader should manage the text. Most newspapers sit between 8 and 12; academic journals commonly exceed 16.

Common questions

Which readability score should I use?

Flesch reading ease for general writing, because it is the most widely recognised and the bands are well established. Flesch–Kincaid grade level is more useful when you need to state an audience level in a specification or a compliance document.

What is a good reading ease score?

Between 55 and 70 for most general-audience writing. Below 40 you are asking real effort of readers outside your field; above 80 the prose may read as simplistic to a professional audience.

Can I improve the score without dumbing the writing down?

Usually, yes. Splitting long sentences at their natural joins and replacing abstract nouns with verbs raises the score and genuinely improves clarity. Replacing precise terms with vague ones raises the score and makes the writing worse.
