Google Ads Character Counter
Check responsive search ad headlines and descriptions against common limits.
Keep ad copy inside limits
Responsive search ads need multiple headlines and descriptions, each with strict character limits. Overlong lines slow down campaign setup and create avoidable back-and-forth.
Responsive search ads cap headlines at 30 characters and descriptions at 90, and anything over is truncated mid-phrase in the live ad, so counting before you paste avoids awkward cut-offs.
This counter checks every pasted headline against a 30-character limit and every description against a 90-character limit, then summarizes how many assets are ready.

The counts run locally and are meant for drafting. Always confirm final limits in the current ad platform before launch.
Frequently asked questions
What does the google ads character counter do?
It checks pasted ad headlines and descriptions against common responsive search ad limits.
What are the responsive search ad limits?
Headlines are capped at 30 characters and descriptions at 90. Each line you paste is counted and marked OK or Too long.
How many headlines and descriptions should I write?
An RSA accepts up to 15 headlines and 4 descriptions and needs at least 3 and 2. Filling more slots gives Google more combinations to test.
Do all characters count as one?
The tool counts each character as one. Google Ads counts double-width characters such as Chinese, Japanese, and Korean as two, so leave extra room for those languages.
