These scores are designed for English
Your text includes words in other scripts, so the scores may not mean much for it. The counts still apply.
Long sentences (over 25 words)
None. Every sentence has 25 words or fewer.
How the scores work
Standard formulas, applied the same way every time. They are estimates, not a judgement of quality.
- Flesch Reading Ease
- 206.835 − 1.015 × (words ÷ sentences) − 84.6 × (syllables ÷ words). Higher means easier.
- Flesch–Kincaid Grade
- 0.39 × (words ÷ sentences) + 11.8 × (syllables ÷ words) − 15.59. An estimated US school grade; lower means easier.
- Syllables
- Estimated for each word: a silent “e” at the end is dropped (but not “-le”), then each group of vowels (a, e, i, o, u, y) counts once, with at least one per word.
- Enough text
- Scores need at least 30 words. Shorter texts show the counts only.
- Sentence length
- Average words per sentence: 18 or fewer is Easy, up to 25 is Medium, more than 25 is Hard. Sentences over 25 words are listed so you can shorten them.
- Counting
- Words, sentences and characters are counted the same way as the Word Counter. Decimals, web addresses and abbreviations such as “e.g.”, “Dr.” and “U.S.” don’t end a sentence, and a line without end punctuation (like a greeting) counts as its own sentence.
- Reading time
- Words ÷ 200 words per minute: “Under 1 min” below 200 words, otherwise rounded to the nearest minute.
- Limits
- The formulas were built for English. Other languages, and text such as lists or code, can get misleading scores.
Questions
What’s a good Flesch Reading Ease score?
Higher scores mean easier reading. The score falls as sentences get longer and words get more syllables, so the quickest way to raise it is to split long sentences and choose shorter words. There is no single pass mark: compare drafts of the same text, and keep your readers in mind.
What grade should I aim for?
The Flesch–Kincaid Grade estimates the US school grade a reader needs to follow the text, so a lower grade means easier text. The right level depends on your readers, so use it to compare drafts rather than as a fixed target. Like the reading ease score, it is an estimate from sentence length and syllables, not a judgement of meaning or quality.
Why is this for English text only?
Both formulas were designed for English, and the syllable count relies on English vowel patterns. Text in other languages or scripts gets numbers that don’t mean much, so the scores are best read for English. Word, sentence and character counts work for any language.
How is reading time estimated?
Reading time divides the number of words by 200 words per minute. Texts under 200 words show “Under 1 min”; longer texts are rounded to the nearest minute, shown with “~” because reading speeds vary.
Is my text stored or sent anywhere?
