Ads character counter

Ad platforms enforce character limits so headlines and descriptions render cleanly across devices and placements. Google, Meta, LinkedIn, and Microsoft each define their own limits per field, and copy that exceeds them either gets rejected at upload or truncated with an ellipsis in the live ad.

A Google Search Ads responsive search ad can include up to 15 headlines (30 characters each) and 4 descriptions (90 characters each). Google's system mixes and matches these to assemble the best-performing combination for each auction.

Meta doesn't enforce a hard limit on primary text, but around 125 characters is where it typically truncates behind a "See more" link in feed placements. Staying under that threshold keeps your full message visible without a click.

It's a close approximation. Google Ads ultimately truncates by rendered pixel width in the live auction preview, not a strict character count — some characters are wider than others, so copy right at the limit can still wrap or truncate slightly differently than shown here.

Yes — paste one line at a time and check it against every field below. Since headlines, descriptions, and primary text all have different limits per platform, checking each field separately is the safest way to avoid truncation before you launch a campaign.
