Readability Checker

Flesch-Kincaid Reading Ease is a 0-to-100 score that tells you how easy a piece of text is to read. Higher is easier. It uses two factors — average sentence length and average syllables per word — to estimate reading effort. A score of 70 means most adults can read it without trouble; 30 means it reads like a legal contract. We use it to make sure marketing pages don't accidentally drift into academic territory. Run drafts through it before publishing, especially for blog content.

60 to 70 is a comfortable target for most web content — it's clear without sounding childish. Blog posts and marketing pages do well in that range. News writing typically scores 60 to 80. Technical documentation and academic papers naturally run lower (40 to 50) because the vocabulary is heavier. E-commerce copy and landing pages can push higher (70 to 80) for fast scanning. Match the score to your audience; what works for a developer blog is wrong for a beginner finance site.

The Flesch Reading Ease formula is: 206.835 − 1.015 × (words ÷ sentences) − 84.6 × (syllables ÷ words). Manual counting on a long article is tedious, so don't bother. Paste your draft into our Readability Checker and you'll get the Flesch score, Flesch-Kincaid grade level, and average sentence length in one shot. Use it on every blog post before publishing — fixing readability after the fact is much harder than catching it at draft stage.

Indirectly, yes. Google has said readability isn't a direct ranking factor, but engagement metrics are influenced by it. A wall of long, dense sentences sends users back to the SERP fast — that hurts you. Real example: I had a finance article that ranked at position 8, scored 35 on Flesch. Rewrote it to score 62. Within six weeks it climbed to position 3, mostly because dwell time doubled. Readability isn't the ranking factor — the user behavior it drives is.

It's a readability score that maps your text to a US school grade. A score of 8 means an average eighth grader can read it. The formula is: 0.39 × (words ÷ sentences) + 11.8 × (syllables ÷ words) − 15.59. For most online content, target grade 7 to 9 — that's where the majority of readers sit. Technical articles can run higher; a beginner-focused tutorial should run lower. Check both Reading Ease and Grade Level together; they catch slightly different problems.

Start with the high-impact fixes: shorten sentences (aim for 15 to 20 words on average), break long paragraphs into two or three lines, and replace heavy words with simpler ones — 'use' beats 'utilize', 'help' beats 'facilitate'. Add subheadings, bullet lists, and bold for the points that matter. After each round, re-run the Readability Checker and watch the Flesch score climb. Then track time-on-page and bounce rate in Analytics — if both improve, the rewrite is doing its job.

60 to 70 on Flesch Reading Ease is a strong target for most blog content, mapping to roughly grade 7 to 9. That's the band where general readers cruise without effort but the writing still feels grown-up. B2B blogs aimed at engineers or analysts can sit lower (50 to 60). Lifestyle, beginner finance, or how-to blogs do better at 70 to 80. Don't chase a number for its own sake — read your draft out loud. If you stumble, the score will too.
