Why Resize Your Facebook Ads?
Facebook runs ads across Feed, Stories, Reels, and Messenger. Each placement uses a different aspect ratio. One image rarely fits all of them well. Upload the wrong size and Facebook crops it automatically. Often badly. A correctly sized creative looks intentional and performs better across every placement.
Understanding Facebook Ad Sizes and Placements
Getting the specs right before you upload saves time. Here's what Meta actually requires.
Common Facebook ad aspect ratios
Per Meta's Ads Guide, Facebook Feed supports aspect ratios from 1.91:1 (landscape) to 4:5 (portrait). Stories and Reels use 9:16 vertical. Square (1:1) sits in the middle and translates well across multiple placements.
Recommended image dimensions by placement
| Placement | Aspect Ratio | Recommended Resolution |
|---|---|---|
| Facebook Feed (1:1) | 1:1 | 1440 × 1440 px |
| Facebook Feed (4:5) | 4:5 | 1440 × 1800 px |
| Facebook / Instagram Stories | 9:16 | 1080 × 1920 px |
| Instagram Reels | 9:16 | 1440 × 2560 px |
Minimum image requirements
Meta sets a floor at 600 × 600 px for 1:1 ads and 600 × 750 px for 4:5. Maximum file size is 30 MB. Supported formats are JPG and PNG only. Aim for the recommended resolutions above. Low-resolution images look weak on modern screens.
How to Resize Ads in Facebook Ads Manager
Ads Manager includes a built-in crop tool. No outside software required.
Step 1: Upload your image and select an objective
Open Ads Manager and create a new campaign. Pick your objective (Sales, Traffic, Awareness, or similar). Navigate to the ad level.
Step 2: Choose your ad format (single image)
Select "Single image or video" as your ad format. Upload your creative. Ads Manager accepts JPG and PNG files up to 30 MB.
Step 3: Use the crop tool to resize for different placements
After uploading, look for an "Edit" or "Crop" button next to each placement thumbnail. A crop grid appears over your image. Drag the grid to reframe the image for that placement's aspect ratio. Click "Confirm" to save. Repeat for every placement you want to customize.
Step 4: Preview your ad on different placements
Click "Preview" in the ad editor. Switch between Feed, Stories, and Reels to see how your creative actually renders. Fix any crop that cuts off your product or headline before you publish.
Step 5: Publish and monitor performance
Once every placement looks right, publish your campaign. Review delivery by placement in Meta's reporting. Cut placements that underperform. Double down on the ones that convert.
Using Automatic Placements vs. Manual Selection
Ads Manager defaults to Automatic Placements. Facebook distributes your ad across all eligible placements and optimizes delivery toward your goal. It's a solid starting point, especially with limited creative assets.
Manual placement selection gives you full control. Choose only the placements your creative is actually sized for. Narrower placement selection means tighter control over how your ad looks. The tradeoff is a smaller potential audience.
A practical approach: start with Automatic Placements, review the placement breakdown after a few days, then cut the ones that aren't delivering.
Why Manual Resizing Isn't Your Only Option
The Ads Manager crop tool works. But it's one placement at a time. Across multiple campaigns and multiple creatives, that adds up fast.
Coinis Smart Resize (inside the Revise tool) generates every placement size from one image in a single step. Feed, Stories, Reels. No dragging crop grids. No switching between placement tabs. Upload once, get every size back in seconds.
It's faster for teams juggling multiple campaigns. It's faster for solo advertisers who don't want to spend 20 minutes cropping before every launch.
Best Practices for Ad Image Sizing
- Start with 1:1 or 4:5. Both work in Feed. Square adapts more cleanly to other placements.
- Center your key visuals. Facebook's auto-crop doesn't know where your product is. Place it centrally to survive any crop.
- Hit the recommended resolution. 600 px is the minimum. Aim for 1440 px. Retina displays punish low-res assets.
- Use JPG or PNG. These are the only accepted formats for Facebook image ads.
- Preview every placement before publishing. A missed crop wastes impressions from the first hour.

Frequently Asked Questions
What image size should I use for Facebook Feed ads?
Meta recommends 1440 × 1440 px for 1:1 ads and 1440 × 1800 px for 4:5 ads. The minimum is 600 × 600 px (1:1) or 600 × 750 px (4:5). Use JPG or PNG, and keep files under 30 MB.
Can I use one image for all Facebook placements?
One image rarely fits every placement without adjustment. Facebook will crop it automatically if the ratio is off, but the crop may cut off key visuals. Use Ads Manager's crop tool to frame your image correctly per placement, or use Smart Resize to generate all sizes at once.
What aspect ratio does Facebook Stories use?
Facebook and Instagram Stories ads use a 9:16 vertical aspect ratio. Meta recommends a resolution of 1080 × 1920 px. Keep key content out of the top 14% and bottom 20% of the frame to avoid UI overlap.
Should I use Automatic Placements or choose manually?
Automatic Placements is a good starting point. Facebook optimizes delivery across all eligible placements. Once you have enough data, review performance by placement and manually cut any that underperform.
