Facebook Feed Ad Sizes
Facebook Feed accepts the widest range of aspect ratios on the platform. Start here when building your base creative.
Recommended resolution and aspect ratios
Per Meta's Ads Guide, Feed images support aspect ratios from 1.91:1 (landscape) to 4:5 (portrait). The recommended resolutions are:
- 1:1 (square): 1440 × 1440 px
- 4:5 (portrait): 1440 × 1800 px
Meta applies a 3% aspect ratio tolerance for Feed placements. A creative that's slightly off ratio won't get automatically rejected, but anything outside that tolerance will.
Minimum pixel requirements
Meta's minimum accepted dimensions are 600 × 600 px for a 1:1 image and 600 × 750 px for a 4:5. Go below those and the upload fails. Minimum dimensions are fine for testing, but always aim for the recommended resolutions in production.
File format and size limits
Facebook Feed accepts JPG and PNG only. The maximum file size is 30 MB. JPG at high quality works well for photography-based ads. PNG handles graphics and text overlays better without compression artifacts.

Facebook Stories Ad Sizes
Stories run full-screen and vertical. A wrong ratio means Meta crops your creative, often cutting off your headline or CTA.
Vertical format requirements (9:16)
Stories ads require a 9:16 aspect ratio. Per Meta's Ads Guide, the recommended resolution is 1440 × 2560 px.
Safe zones to avoid UI overlap
Meta overlays UI elements at the top and bottom of every Story. Leave 250 px at the top and 340 px at the bottom completely free of text and logos. Anything placed in those zones gets obscured in delivery.
Minimum resolution specifications
Meta requires a minimum of 500 px width for Stories uploads. That said, anything below 1440 × 2560 px looks soft on modern high-density phone screens. Use the recommended resolution whenever your source image allows it.

Facebook Reels Ad Sizes
Reels ads appear between organic Reels content. They share the same vertical format as Stories, but the safe zones are stricter.
Full-screen vertical specs
Per Meta's Ads Guide, Reels image ads use a 9:16 ratio with a recommended resolution of 1440 × 2560 px. The maximum file size is 30 MB. Meta applies a 3% aspect ratio tolerance here too.
Resolution and aspect ratio requirements
The minimum accepted resolution for Reels is 600 × 600 px. In practice, anything below the full 9:16 vertical will letterbox and look out of place in the feed. Match the recommended 1440 × 2560 px whenever possible.
Safe text and logo placement zones
Reels carry the tightest safe zones of any Facebook placement. Keep these areas free of text and logos:
- Top: ~14% of the image height
- Bottom: ~35% of the image height
- Each side: ~6% of the image width
That leaves a center band as your active creative zone. Plan your composition around it from the start.

How to Resize Facebook Ads with Coinis Revise
You don't need a designer to hit every placement spec. Coinis Revise handles the resizing automatically.
Use Smart Resize for multi-placement conversion
Smart Resize takes a single creative and outputs it at every Facebook placement size in one step. Start with a 1440 × 1440 px Feed square. Smart Resize produces the Stories and Reels 9:16 versions instantly. No manual cropping. No guessing where your text lands relative to the safe zones.
Step-by-step resizing workflow
- Upload your existing ad image to Coinis Revise.
- Select Smart Resize.
- Choose your target placements, Feed, Stories, Reels, or all three.
- Coinis outputs each variant at spec, with cutting-edge AI models extending the canvas area where needed.
The AI fills extended backgrounds intelligently, it doesn't stretch pixels. Product shots and lifestyle images expand naturally.
Preview before publish
Review every resized variant before going live. Revise shows a placement preview so you can confirm text and logos sit inside the safe zones. If anything drifts into an unsafe area, use Edit text on image to move it, right inside the same tool.

Common Resizing Mistakes to Avoid
Most ad rejections and poor delivery results trace back to a short list of the same errors.
Ignoring aspect ratio tolerance
Meta's 3% tolerance sounds forgiving. It isn't much room. A ratio that's even slightly outside the accepted range for a given placement will fail on upload. Check your ratio before uploading, not after.
Placing text in safe zones
Stories crop 250 px top and 340 px bottom. Reels crop 14% top, 35% bottom, and 6% per side. A CTA or logo placed in those zones disappears in delivery. Use Revise's preview to catch placement issues before you launch.
Using low-resolution source images
Upscaling a 600 × 600 px source to 1440 × 1440 px creates visible quality loss. Start with the highest resolution original you have. If your source is already low-res, run it through AI Upscale in Revise first. Recover the detail before resizing across placements.
