How to Use the Sentence Length Distribution Analyzer
Paste in your text and this tool measures every sentence to show how many fall into short (20 characters or fewer), medium (21-40), and long (41+) categories, along with the average length and standard deviation. A low standard deviation suggests your sentences are similar in length and may read as monotonous, while having more than 70% of sentences in a single category signals a skewed mix. Use it to review the rhythm of a blog post, essay, or marketing copy before publishing.
Writing guides generally recommend mixing short and long sentences for better flow. Run your draft through this analyzer to see the actual distribution, and if one range dominates, deliberately vary sentence length to add rhythm and keep readers engaged.
