Count the sentences in any text and see how long each one is. Long sentences are flagged so you can tighten them.
Your sentences will be listed here as you type.
This sentence counter shows how many sentences your text contains and how long each one is. Besides the total, you get the average, longest and shortest sentence, all measured in words, plus a list of every sentence with a length bar so uneven or overlong sentences stand out immediately.
Sentence length is one of the quickest ways to judge how readable a text is. Readability formulas such as Flesch–Kincaid use average sentence length as one of their two main inputs, and editors routinely hunt for run-on sentences when tightening a draft.
A sentence ends at a period, exclamation mark or question mark, or at the end of the text. Decimal numbers such as 3.5 are not split. Abbreviations like "Dr." or "e.g." can still be counted as an early end, so treat the total as a close estimate.
They measure the number of words in the longest and shortest sentence. The average is the total number of words divided by the number of sentences.
It depends on the audience. General web content usually reads best at roughly 15 to 20 words per sentence, while legal or academic text often runs longer. Use the flag limit to match your own target.
It works for any language that ends sentences with a period, exclamation mark or question mark. Languages that use other end marks, such as the Chinese full stop 。, are not split.
