Reading Time & Readability Calculator
See how long your text takes to read and how easy it is to read — reading time plus Flesch Reading Ease and grade level, updated as you edit.
1 min read — Very easy
Higher reading-ease scores are easier to read; most web copy aims for 60+ (plain English, around a 7th–8th grade level). Shorter sentences and fewer long words raise the score.
Writing for the reader who skims
Two numbers tell you most of what you need to know about a piece of copy: how long it takes to read, and how hard it is. Reading time sets expectations — a labelled “4 min read” is itself a small promise to the reader. Readability tells you whether the writing is doing the work or making the reader do it.
The Flesch formulas reward the two habits that make copy land: shorter sentences and plainer words. You do not have to chase a target score, but if the grade level climbs while you edit, it is usually a sign a sentence has run on or a simpler word was available. Aim for plain English — around a 7th-to-8th-grade level — and the writing will reach more people with less effort from them.
Frequently Asked Questions
How is reading time calculated?
Reading time is the word count divided by a reading speed. Adults read general text at roughly 200 to 265 words per minute, so the tool shows the range and a middle estimate. Dense or technical material reads slower, and skimming reads faster, so treat the figure as a realistic guide rather than a stopwatch.
What is the Flesch Reading Ease score?
It is a readability formula that combines average sentence length and average syllables per word into a score from roughly 0 to 100. Higher is easier: 90-plus is very easy, 60 to 70 is plain English suitable for most web audiences, and below 30 is difficult, academic-style prose. Shorter sentences and simpler words raise the score.
What is the Flesch–Kincaid grade level?
It translates the same sentence-length and syllable inputs into a US school grade. A grade level of 8 means the text should be comfortable for an average eighth-grade reader. Most web writing aims for around grade 7 to 8; lower grade levels reach a broader audience.
How are syllables counted?
Syllables are estimated with a well-known heuristic that counts groups of vowels in each word and adjusts for common endings such as a silent 'e' or trailing '-es' and '-ed'. It is fast and consistent, but it is an approximation — a handful of unusual words will be off by one — so the readability scores are best read as close estimates.
Why does readability matter for copy?
Most readers skim, on small screens, in a hurry. Copy that is easy to read holds attention longer and gets its point across before the reader gives up. Watching the grade level and reading ease as you edit is a simple way to catch sentences that have grown too long or words that have grown too fancy.
Educational estimate only. Reading speed varies by reader and material, and syllable counts are approximate, so readability scores are close estimates rather than exact measurements.
