Writing Style Consistency — Turning Patterns into Numbers
Style consistency can be measured in two main ways: how regular your sentence lengths are, and how varied your vocabulary is without excessive repetition. This tool splits your text into sentences, calculates the standard deviation of their lengths, and computes the ratio of unique words to total words for vocabulary diversity, presenting both as a 0-100 score.
What's measured:
- Sentence length consistency: a smaller standard deviation scores higher
- Vocabulary diversity: a higher unique-word ratio scores higher
- Overall score: the average of the two
Use cases:
- Checking the style of a blog post or article
- Verifying stylistic consistency across a collaboratively written document
- Reviewing sentence patterns in a cover letter or essay
- Spotting text with excessive word repetition
A low score doesn't mean the writing is bad. Prose that deliberately mixes short and long sentences for rhythm can be excellent literature despite a lower score. Treat this as a reference metric only.
FAQ
Sentence length consistency comes from how small the standard deviation of sentence lengths is relative to the average. Vocabulary diversity comes from the ratio of unique words to total words. The final score is the average of the two.
No. This score only measures stylistic consistency and has nothing to do with quality or how engaging the writing is. Prose that deliberately mixes short and long sentences for rhythm can score lower.
You need at least two sentences for a meaningful analysis. With too few sentences, the standard deviation calculation becomes meaningless.
