Why Use an Ad Character Counter?
Every advertising platform has specific character limits for ad headlines and descriptions. Exceeding these limits means your ad copy will be truncated, resulting in incomplete messages and lower conversion rates.
Platform-Specific Character Limits (2025)
- Facebook Ads: 40 characters (headline), 125 characters (description)
- Google Ads: 30 characters (headline), 90 characters (description)
- TikTok Ads: 100 characters (headline), 1000 characters (description)
- Instagram Ads: 40 characters (headline), 125 characters (description)

Best Practices for Ad Copy Length
- Stay under the limit: Aim for 80-90% of the maximum to account for mobile display variations
- Front-load key information: Put your most important message in the first 20 characters
- Test multiple lengths: Create variations to see which performs better
- Consider multilingual ads: Some languages require more characters to convey the same message
