Frequently Asked Questions
Sentences are detected by splitting on sentence-ending punctuation (. ! ?) followed by a space or end of text. Abbreviations and decimal numbers may occasionally cause slight inaccuracies.
Most style guides recommend 3–5 sentences per paragraph for readability. Academic writing may use longer paragraphs, while web writing benefits from shorter ones (2–3 sentences).
The Flesch readability formula uses words-per-sentence as a key metric. Aim for 15–20 words per sentence for general audiences. Sentences over 30 words are considered difficult.
