Analyze text readability score
About the Readability Checker
Content that is hard to read loses readers and rankings alike. The Readability Checker scores your text against six established formulas at once — Flesch Reading Ease, Flesch-Kincaid Grade Level, Gunning Fog, Coleman-Liau, SMOG, and the Automated Readability Index — so you can see how demanding your writing is and roughly what reading level it suits.
Writers, marketers, and editors use it to pitch content at the right audience: simplifying a help article that scores at college level, or confirming a landing page reads easily on a phone. It also reports the underlying statistics — word and sentence counts, average sentence length, reading time — and offers concrete suggestions, like trimming long sentences or cutting complex words.
How to Use the Readability Checker
- Paste or type your text into the input box.
- Click Analyze.
- Read the six readability scores and the grade level each implies.
- Review the statistics and suggestions, then copy a summary or download the full report.
Why Use ToolForge’s Readability Checker

- It reports supporting statistics like reading time and average sentence length, useful for shaping content to an audience.
- All analysis happens in your browser, so unpublished drafts never leave your device.
Frequently Asked Questions
What is a good Flesch Reading Ease score?
Higher is easier. Scores of 60–70 are considered plain English suitable for a wide audience, 70–80 reads easily, and below 50 is fairly difficult, typically college level. Many web writers aim for 60 or above so content is accessible to most readers.
Why does it show several different scores?
Each formula weighs sentence length and word complexity differently, and some target US grade levels while others estimate ease. Looking at all six together gives a more reliable picture than any single formula, which can be thrown off by unusual text.
How can I make my text more readable?
Shorten long sentences, prefer common words over jargon, break content into shorter paragraphs, and use active voice. The checker's suggestions point to the specific issues in your text, and re-analyzing shows the scores improve as you edit.
Is the syllable count exact?
Syllable counting uses an approximation algorithm, since English syllables are irregular and hard to count perfectly by rule. It is accurate enough for reliable readability scoring, but treat the scores as well-grounded estimates rather than precise measurements.
