Paste your blog post, article or essay below. You will instantly get a Flesch Reading Ease score, a grade level, reading and speaking times, and a list of the long sentences worth fixing — all free, and nothing you type leaves your browser.
Long sentences are the number one reason blog posts feel hard to read. Sentences over 25 words are flagged in amber, and over 35 words in red. Showing up to the first 50 sentences.
For most blogs, a Flesch Reading Ease score of 60–70 is the sweet spot: it reads as standard, plain English that a 13–15-year-old can follow, which is exactly right for a general online audience reading on a phone. Scores of 70+ are even easier and suit beginners' guides and how-to posts. Below 50, text starts to feel like an academic paper — fine for a thesis, hard work for a blog reader, who will usually click away.
| Reading Ease | Label | Typical reading level |
|---|---|---|
| 90–100 | Very Easy | Age 11 / Grade 5 |
| 80–90 | Easy | Age 12 / Grade 6 |
| 70–80 | Fairly Easy | Age 13 / Grade 7 |
| 60–70 | Standard | Age 14–15 / Grades 8–9 — ideal for blogs |
| 50–60 | Fairly Difficult | Age 16–18 / Grades 10–12 |
| 30–50 | Difficult | University level |
| 0–30 | Very Confusing | Graduate / specialist level |
Two habits do most of the work: shorter sentences (aim for an average under 20 words) and simpler words (use "use" instead of "utilise", "help" instead of "facilitate"). The grade level simply restates the same idea in school years — a grade of 8 means a typical 13–14-year-old can read it comfortably.
