Check your Facebook ad copy against recommended character limits for each field. Avoid truncation in placements that could cut off your key message or CTA.
Facebook Ad Text Limits
| Field | Recommended | Maximum | |-------|-------------|---------| | Primary Text | 125 characters | 500 | | Headline | 40 characters | 255 | | Description | 30 characters | 255 | | CTA Button | — | Built-in |
Why These Limits Matter
Facebook ads appear across many placements: News Feed, Stories, Audience Network, Instagram (if cross-posted), and more. Each placement shows different amounts of text. Staying within recommended limits ensures your full message shows everywhere.
Writing Effective Ad Copy
- **Primary text hook:** Lead with the pain point or benefit
- **Headline:** Clear, specific, and action-oriented
- **Description:** Reinforce the headline with a second benefit
Mobile-First Consideration
Over 94% of Facebook ad impressions happen on mobile. Test your ad text in mobile preview before publishing, as mobile shows even less text than desktop.
