Key takeaways

  • Use three shapes for almost everything: 1:1 (1080×1080), 4:5 (1080×1350) for feeds, and 9:16 (1080×1920) for Stories and Reels.
  • Keep key text and logos away from the top and bottom ~14% of 9:16 creatives, where the interface sits.
  • Write short: keep primary text to roughly 125 characters so it isn't cut off.
  • Always confirm the latest specs in Meta's Ads Guide, they change.

Safe zones for 9:16 creatives

Stories and Reels overlay the profile name at the top and the call-to-action, captions and buttons at the bottom. Keep logos, prices and key words out of roughly the top and bottom 14% of the frame, and away from the right edge on Reels where action icons appear.

Text guidance

ElementGuidance
Primary textKeep to about 125 characters so it shows before “See more”
HeadlineShort, a few words that state the benefit or offer
On-image textAs little as possible; let the visual carry the message

Video tips

  • Hook in the first 1 to 3 seconds: most people decide to keep watching almost instantly.
  • Design for sound off: add captions.
  • Vertical first (9:16) for Reels and Stories; crop to 4:5 or 1:1 for feeds.
  • Keep the product or person in the centre so crops don’t cut them off.

One creative, every placement

Rather than designing six versions by hand:

  1. Design the master at 9:16 with the subject centred.
  2. Export a 4:5 and a 1:1 crop for feeds.
  3. Check each crop for cut-off text or logos.
  4. Upload all three so Meta can serve the right one in each placement.

1080×1920 pixels (9:16). Keep important text and logos out of the top and bottom ~14% of the frame so they aren't covered by the profile, captions or buttons.

1080×1080 (1:1) is the standard for carousel cards; 4:5 is also supported in many placements. Use the same ratio for every card.
