Free Comma Counter
A comma is the most-used punctuation mark in English — and the most-misused. This counter tallies every comma in your text. Combine it with the sentence count to detect long, comma-heavy sentences that might benefit from a split.
How the Comma Counter Works
Every comma character in your text is counted. Both standard ASCII commas (,) and full-width commas (，) are recognized.
Tips & Best Practices
1More than 3 commas per sentence? Consider splitting
Sentences with 4+ commas often pack too much in. Split into shorter sentences for clarity.
2Use the Oxford comma consistently
Pick one style — Oxford (a, b, and c) or no-Oxford (a, b and c) — and apply it everywhere in your text.
3Avoid comma splices
Joining two complete sentences with only a comma ('I came, I saw') is a comma splice. Use a semicolon, period, or conjunction.
4Comma-to-sentence ratio
Divide commas by sentences. A ratio above 3 suggests overlong sentences; below 0.5 suggests choppy writing.
