> Quick answer: Use 1080×1080 px for square or 1080×1350 px for vertical. Keep text in the center safe zone. Resize with Smart Resize in Coinis Revise to protect focal points automatically.

Facebook Feed Ad Image Dimensions at a Glance
Get these specs right and your ad shows up sharp on every device.
Recommended resolution: 1080×1080 pixels (1:1 ratio)
Per Meta's Ads Guide, the design recommendation for 1:1 is 1440×1440 pixels. For web delivery, 1080×1080 is the widely-used standard and performs well across most campaigns.
Preferred for mobile: 1080×1350 pixels (4:5 ratio)
The 4:5 vertical format gives your ad more screen space on mobile. Meta's design recommendation at this ratio is 1440×1800 pixels. At web delivery size, 1080×1350 is what most advertisers use.
Accepted range: 1.91:1 to 4:5 aspect ratio
Meta accepts any aspect ratio from 1.91:1 to 4:5, with a 3% tolerance. Landscape ratios are allowed but rarely optimal on mobile feeds.
Minimum requirements: 600px width, 600px height (1:1) or 750px height (4:5)
Going below these minimums makes ads look blurry. File format must be JPG or PNG. Maximum file size is 30MB.

Why Aspect Ratio Matters for Feed Ads
The right ratio stops the scroll. The wrong one shrinks your ad into the background.
1:1 (square) occupies standard mobile feed space
Square ads are the safe default. They display consistently across placements and devices.
4:5 (vertical) captures more screen real estate and typically outperforms square
A taller ad pushes organic content further down the feed. More screen space means more attention on your creative.
Wider ratios (1.91:1) work but reduce engagement on mobile
Landscape images show noticeably smaller on mobile feeds. They lose the visual punch that square and vertical formats deliver.
Platform allows flexibility but 1:1 and 4:5 are optimal for most campaigns
Per the Meta Business Help Center, choosing the right aspect ratio for mobile placements is a core best practice. Start with 1:1. Test 4:5 for product-focused campaigns.

Safe Zones: Protecting Text and Logos During Resize
Poor placement hides your message behind Facebook's own UI.
Keep text and logos in the center 1080×1080 pixel core
Even on a 4:5 image, your key content belongs in the center square. This prevents cropping across different screen sizes and devices.
Leave ~250 pixels (14%) free at the top (profile icon overlay)
The advertiser profile icon sits at the top of your ad. Text placed in that zone gets covered automatically.
Leave ~340 pixels (20%) free at the bottom (CTA button overlay)
The call-to-action button overlays the bottom portion of the image. Keep that zone clear of logos and important text.
Avoid edges to prevent cropping on different devices
Devices vary in screen size and pixel density. Padding the edges protects against unexpected cropping you won't catch on desktop.

Step-by-Step: Resizing an Existing Image for Facebook Feed
Follow these five steps and a good creative won't go to waste on bad specs.
Step 1: Determine your target ratio (1:1 or 4:5)
Decide before you touch anything. Switching ratios halfway through forces you to redo the crop.
Step 2: Choose a resizing method (manual tools, online editors, or Smart Resize)
Manual tools give you control. AI-powered tools do the heavy lifting.
Step 3: Set the correct pixel dimensions (1080×1080 or 1080×1350)
Enter these exact dimensions in your editing tool. Don't scale by percentage alone.
Step 4: Preview on mobile to check for cropping
Ads Manager has a built-in preview. Use it before you publish.
Step 5: Verify text is in the safe zone before uploading
Zoom in on the top and bottom of your resized image. If key text is there, move it.

Resizing Methods: Tools and Approaches
Pick the method that fits your workflow and skill level.
Online tools: Canva, Photoshop, free resizers
These work fine for simple resizes. They require manual cropping decisions. One wrong move and you cut off a face or a logo.
Manual cropping: preserve key content, avoid distortion
Crop, don't stretch. Stretching an image to hit a new ratio distorts everything in it.
AI-powered resize: automatically detects key elements and adjusts intelligently
AI resizing reads your image before it changes anything. It finds focal points and adjusts the frame around them instead of blindly cropping.
Why Smart Resize is faster: Coinis Revise analyzes your image and adjusts dimensions while keeping focal points intact
Smart Resize in Coinis Revise handles the whole process in one step. Upload your image, pick the target ratio, and the tool repositions the frame around what matters. No guessing. No manual crop handles to drag.

Common Mistakes to Avoid When Resizing
One mistake here can make a polished ad look amateur.
Stretching images to fit (causes distortion)
Never stretch. Always crop or resize with proportional scaling as the base.
Ignoring safe zones (text gets covered by UI)
Facebook's UI elements overlay your image automatically. Design around them from the start.
Using low-resolution source images (results in blurry output)
Start with the highest-resolution file you have. If your source image is low-res, use AI Upscale in Coinis Revise to recover quality before resizing.
Not testing on actual mobile devices or the Ads Manager preview
Desktop previews can mislead you. Always check on mobile before going live.

When to Use 1:1 vs. 4:5 for Your Campaign
Both formats work. Knowing when to pick each one saves budget.
1:1 (square): safe default, works across most placements
Square runs across Feed, Marketplace, right column, and Stories. It's the lowest-risk starting point for any campaign.
4:5 (vertical): higher engagement on mobile, more screen coverage, better for product-focused creatives
If your campaign lives in the mobile feed, 4:5 is worth testing. The extra height works well for product shots, lifestyle images, and creatives with a lot of visual story to tell.
Test both: A/B test square vs. vertical in the same campaign
Run them side by side with the same copy. Let performance data tell you which format wins for your audience.

Frequently Asked Questions
What is the best image size for a Facebook Feed ad?
For most campaigns, use 1080×1080 pixels (1:1 square) or 1080×1350 pixels (4:5 vertical). Meta's design recommendations go up to 1440×1440 and 1440×1800 at those ratios, but 1080px is the standard web delivery size. The 4:5 vertical format typically performs better on mobile because it takes up more screen space.
What happens if I use the wrong aspect ratio on Facebook Feed ads?
Meta accepts ratios from 1.91:1 to 4:5 with a 3% tolerance, so slightly off-spec images often still run. However, images outside that range get cropped automatically, which can cut off text, logos, or key visual elements. Always confirm your ratio before uploading.
How do I resize a Facebook ad image without cropping out important content?
The safest approach is to keep all text and logos within the center 1080×1080 pixel safe zone before resizing. AI-powered tools like Smart Resize in Coinis Revise detect focal points automatically and adjust the frame around them, which avoids accidental cropping of faces, products, or headlines.
What is the safe zone for Facebook Feed ad images?
Leave roughly 250 pixels (14%) free at the top and 340 pixels (20%) free at the bottom of your image. The profile icon overlays the top and the call-to-action button overlays the bottom. Text or logos placed in those zones will be covered when the ad displays.
