Why Sentence Length Matters

Shorter average sentence length generally makes text easier to read and understand, which is why many style guides recommend keeping average sentence length under roughly 20 words for general audiences. Very long sentences can overwhelm readers, while very short sentences used throughout can feel choppy.

This tool automatically calculates your average words per sentence, so you can quickly check whether your writing leans too long, too short, or sits in a comfortable, readable range.
