Readability Checker
Estimate text difficulty using average sentence length and word length.
What is a Readability Checker?
A readability checker helps estimate how easy or difficult a text may feel to read. This page uses a simple heuristic based on average sentence length and average word length. It does not use an external API or a complex academic formula, which keeps the tool fast and browser-based.
Why Use It
Readable writing helps readers understand and act. Long sentences and long words can be useful in some contexts, but they can also slow people down. A quick readability signal helps you decide whether to simplify, split sentences, or explain technical terms.
Key Features
- Easy, Moderate, or Difficult level.
- Word and sentence counts.
- Average sentence length.
- Average word length.
How to Use
Paste text into the input area and review the level. If the level is difficult, look at average sentence length first. If sentences are reasonable but the text still feels hard, check for long words or dense terminology.
Practical Examples
Use it for landing pages, support articles, school assignments, internal documentation, and email drafts. It is especially helpful before publishing text for a broad audience.
Tips
Use the result as a guide, not a rule. Technical audiences can handle harder text, but most public-facing copy benefits from shorter sentences and clear wording.
