Ad Copy Character Counter

Every ad platform has different character limits for headlines, descriptions, and primary text. Exceeding these limits means your copy gets truncated — the most important part of your message cut off mid-sentence. This tool shows live character counts for your ad copy across all major platforms simultaneously so you can write once and check everywhere.

Meta Ads allow 125 characters of primary text before truncation (though up to 1,000 are technically supported, only 125 show without clicking "see more"), 40 characters for headlines, and 30 for link descriptions. Google Responsive Search Ads allow 30 characters per headline and 90 per description. TikTok allows 100 characters for ad text and 40 for display name.

The most common mistake is writing for one platform and copying to another without checking limits. A 50-character Meta headline gets cut in half on Google. A 200-word Meta primary text shows as three lines on mobile before the fold. This tool prevents those errors by showing exactly where you stand on every platform as you type.

Best practice for ad copywriters: write your headline within 30 characters first (the strictest limit), then expand for platforms that allow more. Front-load the most important information — benefit, offer, or hook — within the first 40 characters so it shows even when truncated. Use this tool every time you write ad copy to catch limit issues before you publish.
