This readability analyzer helps writers, editors, marketers and students estimate how demanding English text feels to a reader. It works as a readability checker, grade level checker, reading difficulty tool and Flesch score calculator in one browser-based workspace.
Use the scores as practical guidance, not as a replacement for editorial judgment. Clear writing also depends on audience, context, structure, examples and terminology.
FAQ
What is readability?
Readability describes how easy or difficult a text is to understand. It is often estimated from sentence length, word length, syllables and vocabulary complexity.
What is a good Flesch score?
A Flesch Reading Ease score from 60 to 70 is usually considered standard. Scores above 70 are easier to read, while lower scores suggest more demanding text.
What is Flesch-Kincaid Grade Level?
Flesch-Kincaid Grade Level estimates the U.S. school grade a reader may need to understand the text comfortably.
What is Gunning Fog?
The Gunning Fog Index estimates reading difficulty from average sentence length and the percentage of complex words in the text.
How can I improve readability?
Shorten long sentences, remove unnecessary words, choose simpler vocabulary where possible, and split dense paragraphs into clearer sections.
