## About

Paste any text and see the word count of every sentence, the average and median sentence length, and a distribution chart that shows how your sentences stack up against the recommended 15–20 word range.

Sentences over 35 words are flagged for easy editing. The most common readability advice is "vary your sentence length," and this tool shows you whether you are doing that or not.

## How to use

1. **Paste your text** — Drop in an article, essay, email, or any block of prose you want to check.
2. **Read the headline numbers** — Total sentences, average, median, and longest. If the average is over 25 words, your prose is dense; under 14, it may feel choppy.
3. **Fix any sentence over 35 words** — The tool flags run-on candidates. Each one is shown in full so you can split it without losing context.

## FAQ

### What is a good average sentence length?

For general-audience writing, 15–20 words is the sweet spot. For academic and professional writing, 20–25 words is normal. The Hemingway editor aims for under 14 words average. Above 25 words, readability drops sharply for most readers.

### How long is too long for a sentence?

Anything over 35 words is hard to parse on the first read. Anything over 50 words is almost certainly a run-on that should be split. The Uttir Sentence Length Checker flags any sentence over 35 words so you can decide.

### Should every sentence be short?

No — short sentences in a row become monotonous. Good writing varies sentence length deliberately: short sentences for emphasis, longer ones for nuance. Aim for a mix where the average is 15–20 words.

### Does this count syllables?

No — this counts words per sentence, which is the readability metric most style guides (Strunk, Plain English Campaign) recommend. Syllable counting is a different (and much more complex) analysis used in Flesch-Kincaid scoring.
