Meta Image & Video Ads · Specs, Formats & Best Practices

Single image and single video are the foundational Meta ad formats — the simplest, most widely used, and most compatible with all placements. Getting the specs right ensures your creative renders correctly across Feed, Stories, Reels, Marketplace, and the Audience Network. This guide covers every specification for image and video ads across all placements, the text limits that vary by placement, and the creative principles that drive performance.

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

SpecificationRequirement
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)

CaptionsSRT file or auto-generated; required for accessibility; most mobile video plays muted

Text Element Specifications

ElementCharacter LimitTruncation
Primary text125 characters before "see more" (2,200 max)Truncated after 125 chars on most placements; front-load key message
Headline27 characters recommended (40 max)Truncated after ~27 chars in some placements; keep tight
Description27 characters recommended (30 max)Not always shown; supplemental to headline
Call to action buttonPredefined options onlySelected 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

PlacementBest Image RatioBest Video RatioNotes
Facebook Feed1:1 or 4:51:1 or 4:54:5 takes more screen real estate than 1:1
Instagram Feed1:1 or 4:51:1 or 4:5Same as Facebook Feed
Facebook/Instagram Stories9:169:16Full-screen vertical; safe zone critical
Instagram Reels9:169:16Maximum 60 seconds; first 3 seconds critical
Facebook Marketplace1:11:1Square format dominant; product-focused imagery
Audience Network (in-app)1:1 or 9:169:16 or 16:9Varies 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.
