Reading time

Scores use the standard Flesch Reading Ease and Flesch–Kincaid Grade Level formulas. Syllables are counted with a heuristic, so figures are close approximations. For most web content, aim for a Reading Ease of 60+ (around 8th-grade level). All analysis runs in your browser.

This readability checker scores your text for reading ease, grade level and reading time. Paste any text to get its Flesch Reading Ease score, an approximate US grade level, word and sentence counts and an estimated reading time. It’s a fast check for content, SEO and UX teams who want clear, accessible writing.

Readable copy keeps more readers on the page and is easier for search engines and AI assistants to summarise accurately.

What is Flesch Reading Ease?

Flesch Reading Ease is a 0–100 score where higher means easier to read. It’s based on average sentence length and average syllables per word: shorter sentences and simpler words score higher. The companion Flesch–Kincaid grade level estimates the US school grade needed to read the text comfortably.

What score to aim for

For most web and marketing content, aim for a Reading Ease of 60 or above — roughly an 8th-to-9th-grade level, the sweet spot for a general audience. Technical or academic writing naturally scores lower; that’s fine if your readers are specialists, but it’s worth knowing where you sit.

How to make text more readable

Shorten long sentences, prefer common words over jargon, and break dense paragraphs into smaller chunks. Read it aloud — anywhere you stumble is usually a candidate for simplification. Small edits to sentence length and word choice move the score quickly.
