Why Count Sentences?
Sentence count is a fundamental metric for evaluating readability and writing structure. Varying your sentence lengths creates rhythm and keeps readers engaged. Academic style guides recommend an average of 15 to 20 words per sentence for maximum clarity, while legal and technical documents often exceed 30 words per sentence, reducing accessibility.
Ideal Sentence Length by Context
12–18 words per sentence. Short sentences improve scanning and mobile readability.
20–30 words per sentence. Complex arguments need longer structures but should vary in length.
Variable length. Mix short punchy sentences with longer flowing ones for rhythm and tension.
