Safe zone for Stories
Stories ads have interactive elements (CTAs, swipe-up prompts, profile icons) that overlay the bottom and top of the image. The safe zone — the area guaranteed to be unobstructed — is approximately the central 1080 x 1420 px of a 1080 x 1920 px image. Keep critical content (product, face, key message) within this zone.
Text in images
Meta previously had a "20% text rule" (rejecting images where text covered more than 20% of the image area). This rule was officially retired but the principle remains valid for performance: images with heavy text overlays consistently receive lower delivery and higher CPMs than image-forward creative. Keep text overlays minimal — use the primary text field for copy, not the image itself.
Video Ad Specifications
| Specification | Requirement |
|---|---|
| Recommended dimensions (Feed) | 1080 x 1080 px (1:1) or 1080 x 1350 px (4:5) |
| Recommended dimensions (Stories/Reels) | 1080 x 1920 px (9:16) |
| Supported aspect ratios (Feed) | 16:9 to 9:16; 1:1 and 4:5 recommended |
| File formats | MP4, MOV, GIF (MP4 recommended) |
| Maximum file size | 4 GB |
| Minimum length | 1 second |
| Maximum length (Feed) | 241 minutes (most effective under 15 seconds for performance ads) |
| Maximum length (Stories/Reels) | 60 seconds for Stories; 60 seconds for Reels ads |
| Frame rate | Minimum 30fps recommended; maximum 60fps supported |
| Bit rate | Minimum 1 Mbps (4 Mbps+ recommended) |
| Audio | Stereo AAC audio recommended at 128kbps+ |
| Thumbnail | Automatically generated from first frame; custom thumbnail recommended — avoid text-heavy thumbnails |
| Captions | SRT file or auto-generated; required for accessibility; most mobile video plays muted |
Text Element Specifications
| Element | Character Limit | Truncation |
|---|---|---|
| Primary text | 125 characters before "see more" (2,200 max) | Truncated after 125 chars on most placements; front-load key message |
| Headline | 27 characters recommended (40 max) | Truncated after ~27 chars in some placements; keep tight |
| Description | 27 characters recommended (30 max) | Not always shown; supplemental to headline |
| Call to action button | Predefined options only | Selected from Meta's list — no custom text |
Primary text is your main copy area — the only element with significant space for messaging. Write the first 125 characters as a complete, compelling statement that works without the "see more" expansion. The headline (below the creative) should reinforce or complement the primary text with a specific, direct value statement.
Specifications by Placement
| Placement | Best Image Ratio | Best Video Ratio | Notes |
|---|---|---|---|
| Facebook Feed | 1:1 or 4:5 | 1:1 or 4:5 | 4:5 takes more screen real estate than 1:1 |
| Instagram Feed | 1:1 or 4:5 | 1:1 or 4:5 | Same as Facebook Feed |
| Facebook/Instagram Stories | 9:16 | 9:16 | Full-screen vertical; safe zone critical |
| Instagram Reels | 9:16 | 9:16 | Maximum 60 seconds; first 3 seconds critical |
| Facebook Marketplace | 1:1 | 1:1 | Square format dominant; product-focused imagery |
| Audience Network (in-app) | 1:1 or 9:16 | 9:16 or 16:9 | Varies by app; interstitial and native formats |
When using Advantage+ Placements (Meta's recommended default), providing both 1:1 and 9:16 assets covers all major placements. Meta will select the appropriate asset for each placement automatically.
Image Creative Principles
- Thumb-stopping visual in the first moment. Feed ads compete with organic content from friends and family. The image must earn attention in under 1 second. High-contrast images with a clear, prominent subject outperform complex compositions.
- Show the product clearly. For e-commerce, the product should be immediately identifiable — white background or minimal background product shots often outperform lifestyle photography for direct response.
- People perform well. Images featuring human faces and direct eye contact capture attention and create emotional connection. Genuine, natural-looking people outperform stock photography models.
- Minimise text in the image. Text in images reduces delivery and competes with the primary text field. Reserve image space for visual communication; use primary text for copy.
- Match the feed aesthetic. Ads that blend naturally with organic content (authentic photography, user-generated style) often outperform highly polished commercial imagery — they are less likely to be skipped as obvious ads.
Video Creative Principles
- Hook in the first 3 seconds. The average Meta video ad loses 47% of viewers in the first 3 seconds. The opening frames must immediately communicate relevance — start with the product, the problem being solved, or a visually arresting moment. Do not open with a logo or brand introduction.
- Design for silent viewing. The majority of mobile video plays on mute. Key messages must be communicable without sound — use captions, on-screen text for key points, and visual storytelling that works without audio. Enable captions on all videos.
- Vertical or square first. Over 90% of Meta users are on mobile. Design video in 9:16 (Stories/Reels) or 1:1 (Feed) aspect ratios. Landscape 16:9 video — designed for television and desktop — uses only 25% of a mobile screen.
- Short for performance; longer for consideration. Direct response video ads perform best at 6–15 seconds — long enough to communicate value, short enough to hold attention. Consideration and brand storytelling can use 30–90 seconds effectively with the right audience and objective.
- Place brand and CTA early for awareness. If brand awareness is the goal, show your brand name and product within the first 3 seconds — many viewers never reach the end of the video.
