What is Sentence Counter — Count Sentences & Analyze Sentence Length?
A sentence counter counts the total number of sentences in a block of text, calculates the average sentence length in words, and identifies very long sentences that may hurt readability. Search engines and readability formulas both factor in sentence length — shorter sentences (15—20 words on average) are easier to read and score better on readability indexes.
