Sentence Counter
Count sentences, words and average sentence length, abbreviation-aware. Your work stays on this device whenever possible.

- Scroll the numbered list to see exactly where each sentence was split.
What Sentence Counter does
Count sentences, words and average sentence length, abbreviation-aware.
The page reads Unicode text in memory and applies the selected text rule directly. It does not create a server-side copy. For Sentence Counter, the operation is specifically to count sentences, words and average sentence length, abbreviation-aware.
Worked example
The sample text "Dr. Smith arrived at 9.30 a.m. on Monday. She checked the results twice! Were they correct? Yes, and the report was sent at 10 a.m." is counted as 4 sentences and 25 words, with 6.3 words per sentence.
When Sentence Counter is the right tool
- Checking an essay or article for overly long sentences.
- Meeting a sentence-count requirement in an assignment or form.
How to verify the result
Read the beginning, middle, and end of the result. Punctuation, blank lines, and non-English characters are the most useful things to spot-check. The final Sentence Counter output should visibly match this goal: Count sentences, words and average sentence length, abbreviation-aware.
Important limitations
Sentence ends are detected from punctuation followed by a capital letter or number; unusual abbreviations not in the built-in list can split a sentence early.

Frequently asked questions
How does it decide where a sentence ends?
A sentence ends at a period, exclamation mark or question mark followed by a space and a capital letter or number, or at the end of the text. The numbered list shows each sentence so you can check the split.
Will Dr. or e.g. break a sentence?
No. Common abbreviations such as Mr., Mrs., Dr., Prof., e.g., i.e., a.m., p.m., etc. and Inc. are not treated as sentence ends, and decimals like 9.30 stay together.
What is a good average sentence length?
Plain-English guides often aim for about 15-20 words per sentence on average. Much longer averages are harder to read, especially on phones; use the longest-sentence figure to find candidates to split.
How is this different from the word counter?
The word counter focuses on words, characters and reading time. This tool lists every sentence it found, so you can see and fix the splits, and it reports sentence length statistics.
Does it handle quotes and brackets?
Yes. A closing quote or bracket right after the punctuation stays with the sentence, and a new sentence may start with an opening quote.
