Reading Time Calculator — WPM, Flesch score & read time

Blog posts, articles, and documentation all benefit from a reading time estimate — readers decide whether to engage based on how long something will take. The "5 min read" badge on a blog post comes from a simple calculation: word count divided by average reading speed (around 200-250 words per minute for adult readers). This calculator gives you that number along with readability scores that tell you whether the text is accessible to your target audience.

Paste any text and the calculator shows estimated reading time at three speeds (slow: 150 wpm, average: 238 wpm, fast: 350 wpm), word count, sentence count, paragraph count, average sentence length, average word length, and syllable count. The Flesch Reading Ease score (0-100) and Flesch-Kincaid Grade Level estimate how easy the text is to read — scores above 70 are considered easy for most adults, below 50 requires a college reading level.

Writing feedback loop. After drafting content, paste it here to check whether the grade level matches your audience. A technical blog post for developers can tolerate a higher grade level than a marketing landing page aimed at general consumers. Short sentences, common words, and active voice all improve the score.

Calibrate reading time badges. "5 min read" estimates vary by publication. Medium uses 275 wpm. This tool lets you choose your own speed benchmark and see the exact minutes and seconds.

Improving your readability score. The most effective ways to raise your Flesch Reading Ease score are to shorten your average sentence length and choose common words over technical jargon. Long compound sentences can usually be split into two simpler sentences. Passive voice adds words and syllables without adding meaning — prefer active constructions. After editing, paste the revised text back to see the numerical improvement instantly.

Use cases beyond blogging. Technical writers use grade level to verify documentation is accessible to the intended skill level. Email marketers check reading difficulty to match their subscriber audience. SEO content teams verify minimum word counts and readability thresholds before publishing. Product teams check help article clarity before shipping to users. The tool handles any text length, from a short email to a 5,000-word article, and the statistics update instantly without any submission step.
