Does a low readability score mean the writing is bad?

Not necessarily — it depends on the intended audience. Dense academic or legal writing scoring low can still be well-written for its specific expert readership.

Can I improve my score without changing my ideas?

Yes — shortening sentences, breaking up long paragraphs, and swapping complex words for simpler synonyms usually raises the score without changing the underlying content.

Is Flesch Reading Ease used for languages other than English?

The formula was designed and calibrated specifically for English; other languages typically need their own adapted formulas to give meaningful results.

What Is a Good Readability Score?

A readability score is only useful once you know what number you're actually aiming for — and that target changes depending on who's reading.

How the Flesch Reading Ease scale works

90-100: Very easy — understandable by an average 11-year-old.
70-89: Easy to fairly easy — comfortable for most adults, typical of popular fiction and mainstream news.
60-69: Standard — plain English, widely considered the sweet spot for general web content.
30-59: Fairly difficult to difficult — typical of more technical or formal writing.
0-29: Very difficult — dense academic, legal, or scientific writing.

What to actually aim for

For general web content, blog posts, and marketing copy, a score of 60-70 is a widely used target — plain, clear English that doesn't feel dumbed down but is easy for a broad audience to read quickly. Instructional content and customer-facing help articles often aim even higher, in the 70-80 range, since clarity matters more than sophistication there.

Academic papers, legal documents, and technical documentation for expert audiences reasonably score lower — the audience already has the background knowledge to handle denser sentences and specialized vocabulary.

Why simpler often performs better online

Most web readers skim rather than read closely, especially on mobile. Content that scores well on readability tends to hold attention better and gets cited more often by search engines and AI summarization tools, since it's easier to extract a clear answer from a well-structured, plainly written passage.

Readability isn't the same as "dumbing down"

A high readability score doesn't mean shallow content — it means the ideas are expressed clearly. Some of the most respected writing advice (across journalism and technical writing alike) pushes toward shorter sentences and simpler words specifically because it makes complex ideas easier to follow, not because it avoids complexity.

The bottom line

There's no single "correct" score — the right target depends on your audience. For most everyday web writing, 60-70 is a solid, practical goal.
