Comprehensive Guide & Technical Mechanics

About Sentence Counter — Free Online Tool

Sentence Counter counts the sentences in a passage and divides the word total by that figure to give an average sentence length.

Sentences are found by splitting the text on runs of full stops, question marks and exclamation marks and discarding the empty pieces. That is a blunt rule, with one consequence worth knowing: an abbreviation such as Dr. or Inc. ends a sentence as far as the count is concerned, and so does the point in a decimal number, so citation-heavy or technical writing reads as having more sentences than it really has. On prose with ordinary punctuation the figure matches what you would arrive at by hand, and the average alongside it is the number to watch when a paragraph feels heavy.

Nothing is posted anywhere. The passage sits in the page while it is measured and goes when the tab does.

Checking that an average sentence stays near the 15 to 20 words most style guides ask for, breaking up a paragraph that reads as one long breath, comparing the pacing of a draft against a published piece, and counting sentences for a quota on a translation or subtitle job.
