Readability Score Checker – ToolPremier

Aim for Flesch score 60–70 for general web content · Grade 8 is ideal for most audiences

How it works
Convert in three steps

1. Paste your content

Drop in a blog post, article, product description, or any block of text. The tool works on any length - longer texts produce more accurate scoring.

2. Review your scores

Get the Flesch Reading Ease score (0-100), Flesch-Kincaid Grade Level, and a plain-language summary of what the numbers mean for your audience.

3. Improve your copy

Use the word and sentence-level breakdown to find passages that are too dense - long sentences, high syllable counts, or complex vocabulary - and simplify them.

FAQ
Common questions
The Flesch Reading Ease score rates text on a 0-100 scale. Higher scores mean the text is easier to read. Scores between 60-70 are considered standard and readable by most adults. Scores below 30 are very difficult – appropriate for academic or legal documents. Scores above 70 are easy – suitable for a general audience or consumer-facing content.
It depends on your audience. For general web content and blog posts, aim for 60-70 (standard). For consumer-facing copy, landing pages, or email, aim above 70 (easy). For technical documentation or professional audiences, 40-60 is acceptable. Academic papers and legal content often score below 30 intentionally.
Readability is a content quality signal. Pages with very low readability scores often have high bounce rates – readers leave when content is too dense. While Google doesn’t directly use a readability formula, content that’s difficult to read tends to underperform on engagement metrics that do influence rankings. Clear, readable content also tends to earn more natural links and shares.
Flesch Reading Ease gives a score from 0-100 (higher = easier). Flesch-Kincaid Grade Level translates that into a US school grade (e.g., Grade 8 means the text is readable by a typical 8th grader). Both are calculated from the same inputs – sentence length and syllable count – but expressed differently. Grade Level is often more intuitive for content teams to work with.

About the Readability Score Checker
Readability affects whether people actually read what you write. Content that scores well on the Flesch scale isn’t dumbed-down – it’s clear. Short sentences, common vocabulary, and active voice produce readable content without sacrificing depth or authority. This tool runs the standard Flesch-Kincaid analysis on any block of text and returns the core readability metrics: Reading Ease score, Grade Level, sentence count, average sentence length, and average syllables per word. Use the results to identify paragraphs that need breaking up, sections with unusually dense vocabulary, or an overall tone mismatch with your target audience.
