- Minimum accepted resolution is 600×600 px (1:1) or 600×750 px (4:5) — below that, Meta rejects the upload.
- Only JPG and PNG are accepted. Max file size is 30 MB.
- Meta allows a 3% aspect ratio tolerance, so slightly off-ratio images still pass review.

Facebook feed ads live and die on creative quality. Wrong dimensions mean automatic cropping, blurry images, or rejected uploads. Here's the exact process to resize correctly, every time.
> TL;DR: Use 1440×1440 px for square (1:1) or 1440×1800 px for vertical (4:5). JPG or PNG, max 30 MB. Smart Resize in Coinis Revise handles the format automatically.
What Size Should Your Facebook Feed Ad Be?
Per Meta's Ads Guide, the recommended resolutions for Facebook feed image ads are 1440×1440 px (1:1 square) and 1440×1800 px (4:5 vertical). These sizes produce the sharpest results across desktop and mobile.
The minimum accepted resolution is 600×600 px for square and 600×750 px for vertical. Below that, Facebook rejects the image. At minimum size, quality takes a hit on high-density screens. Shoot for the recommended resolution.

Aspect Ratios Explained
The aspect ratio is the relationship between an image's width and height. Choose the wrong ratio and Facebook crops your creative automatically. That means cut-off products, chopped logos, or text that disappears off frame.
Square (1:1 aspect ratio)
Square is the most flexible format. It displays well on both desktop and mobile. The recommended size is 1440×1440 px. Use square when you want one creative that works across multiple placements without adjustment.
Vertical (4:5 aspect ratio)
Vertical ads cover more screen real estate on mobile feeds. More space means more attention. The recommended size is 1440×1800 px. If your audience skews mobile, 4:5 is worth the extra crop work.
Meta's aspect ratio tolerance is 3%. Images that fall slightly outside a clean ratio still pass review, as long as they stay within that 3% window.
How to Resize Your Image for Facebook Feed
These six steps walk through resizing from start to finish.
Step 1: Choose your image
Start with the highest-resolution version you have. Upscaling low-res images introduces blur and noise. If your source image is below 600 px on either side, use Coinis Revise's AI Upscale to fix that before resizing.
Step 2: Select your target aspect ratio
Pick 1:1 or 4:5 based on your audience and goals. Mobile-first campaigns benefit from 4:5. When in doubt, 1:1 is the safer default.
Step 3: Upload or import to a resizing tool
Open your tool of choice. Coinis Revise includes Smart Resize, which applies Facebook feed presets automatically. Upload your image and select the target placement.
Step 4: Apply the resize
Set output dimensions to 1440×1440 px or 1440×1800 px. Smart Resize crops and scales without stretching. Manual tools require you to lock the aspect ratio before resizing to avoid distortion.
Step 5: Preview the result
Check the crop. Important elements, like faces, products, and logos, should sit well within the frame. Adjust the crop anchor if anything is cut off.
Step 6: Download and use in your ad
Export as JPG or PNG. Verify the file size is under 30 MB. Upload to Ads Manager and attach to your campaign.
Common Resizing Mistakes to Avoid
Stretching the image. Stretching distorts your creative. Always maintain the original aspect ratio first, then crop to the target dimensions.
Using the minimum resolution. 600 px is the floor, not the goal. Images at minimum size look soft on high-density screens. Aim for 1440 px.
Text-heavy images. Facebook recommends keeping image text minimal. Heavy text overlays can reduce ad delivery. Put your main message in the primary text field, not baked into the image.
Skipping the crop preview. Always check the preview before downloading. One missed step can mean a cropped-out product or a broken headline.
Wrong file format. Facebook only accepts JPG or PNG for image ads. WEBP, GIF, and PSD are not supported for static image placements.

Frequently Asked Questions
What is the best image size for a Facebook feed ad?
Meta recommends 1440×1440 px for square (1:1) and 1440×1800 px for vertical (4:5). Both are accepted in the Facebook feed. The minimum is 600×600 px (1:1) or 600×750 px (4:5), but minimum-size images look soft on high-density screens.
Can I use a landscape image for a Facebook feed ad?
Facebook feed ads support aspect ratios from 1.91:1 down to 4:5, so landscape images technically fit the spec. That said, square (1:1) and vertical (4:5) take up more screen space in the feed and tend to perform better. Landscape is better suited to link previews than image ads.
What happens if my image aspect ratio is slightly off?
Meta applies a 3% aspect ratio tolerance. If your image falls within 3% of the stated ratio, it will pass review without being cropped. Anything beyond that tolerance gets auto-cropped by Meta's system, which can cut off important visuals.
What file types does Facebook accept for image ads?
Facebook accepts JPG and PNG for image ads. The maximum file size is 30 MB. Other formats like WEBP, GIF, and PSD are not supported for static image ad placements.
