What is a sentence counter?
A sentence counter identifies the boundaries of each sentence — usually marked by periods, exclamation marks or question marks — and reports the total. It also shows the average number of words per sentence.
Why sentence length matters
Shorter sentences are generally easier to read. Text aimed at general audiences tends to use 15–20 words per sentence on average, while complex academic writing often exceeds that. Knowing your average helps you match your audience.
