- Aspect ratios supported: 1.91:1 to 4:5 (1:1 and 4:5 recommended)

- Text overlay: No hard limit, but ads with less than 20% text in the image tend to deliver better
Copy specifications:
- Primary text: 125 characters visible before "...See More" truncation (up to 63,206 max)
- Headline: 27 characters before truncation (up to 255 max)
- Link description: 27 characters before truncation
Pro tip: Design for 4:5 (1080×1350px) when Feed is your primary placement — it occupies more screen real estate than 1:1 on mobile, which improves visibility and engagement.

Spec Tips for Production Teams
Always design mobile-first. 98%+ of Facebook ad views happen on mobile. If your ad looks great on desktop but the text is unreadable on phone, it fails.
Use 4:5 when Feed is primary. 4:5 takes up 20% more screen space than 1:1 on mobile — that's a significant visibility advantage.
Add captions to all video. 80%+ of Feed video is viewed with sound off. Captions aren't optional — they're essential for message delivery.
Plan for truncation. Write your most important copy in the first 125 characters of primary text. Front-load the hook — most users won't tap "See More."
Export at highest quality, then compress. Start with the highest resolution your production pipeline supports. Meta compresses on upload; giving it more to work with preserves quality.
Facebook Ad Specs FAQ
What's the best Facebook ad size for 2026?
1080×1080px (1:1) is the most versatile — it works across Feed, Marketplace, and search results. For maximum Feed impact on mobile, use 1080×1350px (4:5).
Does Facebook still penalize ads with too much text?
Meta removed the formal 20% text rule, but ads with heavy text overlay still tend to receive reduced delivery. Best practice: keep text to 15-25% of the image area.
What video resolution should I upload?
Upload the highest resolution you have (1080p minimum). Meta will compress and optimize for different placements. Starting with higher quality preserves visual clarity after compression.
Can I use the same creative for Facebook and Instagram?
Yes — the same specs generally apply across Meta placements. However, Instagram tends to favor cleaner visuals and tighter aspect ratios. Test placement-specific creative when possible.
