Length profile
48 sentences averaging 17 words, with a run of nine consecutive sentences between 15 and 19 words — the flattest stretch in the passage.
How the Sentence Length Variator works
- Paste several paragraphs; a single paragraph is too short to show a pattern.
- Read the length profile and look for runs where consecutive sentences sit in the same band.
- Break one long sentence in the run, or merge two short ones, and the rhythm changes immediately.
FAQ
Is there an ideal sentence length?
No. What reads badly is uniformity — a page where every sentence lands between 15 and 20 words feels monotonous regardless of how good each one is. Variation is what creates rhythm.
Does a short sentence always add emphasis?
It does when it follows long ones. A short sentence among other short sentences is just short. The effect comes from the contrast, which is why the run matters more than any single length.
Should I aim for a particular average?
The average tells you less than the spread. Two passages can share an average of 17 words while one alternates between 6 and 30 and the other never leaves the teens.
