Sentence Counter

The counter identifies sentence boundaries using periods, exclamation marks, and question marks followed by whitespace or end of text. It handles common abbreviations (Mr., Dr., etc.) and decimal numbers to avoid false splits. Ellipses (...) are treated as a single sentence terminator.

Beyond sentence count, you get paragraph count, word count, character count (with and without spaces), average words per sentence, average sentence length, and reading time estimate. These metrics help writers evaluate their content's structure and readability.

Average sentence length is the total word count divided by the total sentence count. Professional writing typically averages 15-20 words per sentence. Academic writing tends to be longer (20-25 words). Short sentences (under 10 words) improve readability but too many in a row can feel choppy.

Yes — sentence length variation is a key indicator of good writing. If most of your sentences are the same length, your writing may feel monotonous. The statistics help you identify patterns: too many long sentences reduce readability, while varied lengths create a natural rhythm.

Yes — sentences within quotation marks or parentheses that end with terminal punctuation are counted individually. The tool treats the text as a continuous stream and applies the same boundary detection rules regardless of surrounding quotes or brackets.
