Quick reference
Build each format in the intended aspect ratio whenever possible. Many readability, crop, and safe-zone issues start when one format is resized into another.
Specs are only the baseline
A technically valid file can still perform poorly as an ad. Preview the final placement with caption, CTA, and brand details before approving creative.
Check safe zones before launch
Vertical placements should always be reviewed with safe-zone overlays, especially when the video includes subtitles, prices, logos, or important lower-frame information.

Approval checklist
- Export each placement at its intended aspect ratio.
- Avoid scaling low-resolution images up to 1080px wide.
- Check vertical placements with safe zones visible.
- Use separate edits for Feed, Stories and Reels when needed.
- Keep a preview image with the final approval record.
Frequently asked questions
Are Instagram ad specs enough to approve creative?
No. Specs confirm the canvas, but a placement preview catches readability, crop and interface problems.
Which Instagram ad format should I design first?
Start with the placement that matters most for the campaign. For many mobile-first campaigns, that means a 9:16 vertical version plus a 4:5 feed version.
Does AdsOverlay replace official Meta documentation?
No. Use official Meta documentation for policy and upload requirements, and AdsOverlay for independent creative preview.
