Meta Ads
The Ad Copy Length Checker validates your paid-ad text against the real character limits for Google Ads and Meta (Facebook & Instagram) Ads as you type. It shows a live count for every field — headlines, descriptions, primary text, display paths — and flags anything that runs over before you ever paste it into Ads Manager. No sign-up, all in your browser.

Frequently asked questions
What is the character limit for a Google Ads headline?+
Google Ads responsive search ad headlines are limited to 30 characters each, with up to 15 headlines per ad. Descriptions allow 90 characters.
How long can Facebook and Instagram ad text be?+
Meta recommends primary text around 125 characters before it truncates, headlines up to 40 characters, and link descriptions up to 30 characters.
Does this tool send my ad copy anywhere?+
No. Everything is counted in your browser as you type — nothing is uploaded or stored.
Why do my ads get rejected for length?+
Most platforms reject or auto-truncate fields that exceed the limit. Checking length before you upload avoids disapprovals and cut-off copy.
