> Quick answer: Facebook feed image ads need a minimum of 600 x 600 px (1:1) or 600 x 750 px (4:5), with a recommended resolution of 1440 x 1440 px or 1440 x 1800 px. Stories require 9:16. Max file size is 30 MB. JPG or PNG only.
Upload the wrong image size and Facebook crops it automatically. Sometimes badly. This guide covers every placement spec and the fastest way to resize without losing quality.

Why Image Size Matters for Facebook Ads
Incorrect dimensions trigger automatic cropping or outright rejection. Either way, your ad underperforms before a single person sees it.
How incorrect sizes affect ad quality and performance
Wrong dimensions mean Facebook makes a decision for you. It might crop your headline out of frame. It might stretch a low-res image until it looks blurry. Both hurt CTR. Neither is recoverable after launch.
Platform-specific cropping and display logic
Facebook applies different display logic per placement. Feed, Stories, Carousel, and Instagram all pull from the same creative but display it differently. An image sized for Feed gets cropped when Facebook forces it into a Stories frame. That can mean a product cut in half or a CTA completely hidden.

Facebook Feed Image Dimensions
Per Meta's Ads Guide, feed image ads accept aspect ratios from 1.91:1 to 4:5. That range covers most use cases, but two ratios do most of the work.
Minimum vs. recommended pixel sizes
The minimum resolution is 600 x 600 px for 1:1 or 600 x 750 px for 4:5. Facebook accepts these, but they look soft on modern screens. The recommended resolution is 1440 x 1440 px (1:1) or 1440 x 1800 px (4:5). Start at the recommended size every time.
Optimal aspect ratios (1:1 and 4:5)
1:1 is the safest default. It works across Feed, Carousel, and most cross-platform placements. 4:5 takes up more vertical space in Feed. More screen space generally earns more attention.
File size and format requirements
Facebook accepts JPG and PNG only. Maximum file size is 30 MB. Compressed JPGs at high quality work well for most ad creatives. PNG is better when you need transparency or sharp text edges.

Size Requirements Across Facebook Placements
Each Facebook placement has its own rules. Getting them right prevents automatic cropping at delivery.
Stories ads (9:16 ratio)
Stories require a 9:16 or 4:5 aspect ratio. The full-screen 9:16 format fills the entire display. If you go with 9:16, protect a safe zone. Leave 250 px clear at the top and 340 px clear at the bottom. Facebook's UI overlays sit in those areas. Any text or visual element placed there will be hidden.
Carousel ads (1:1 and 4:5)
Each Carousel card needs a minimum of 1080 x 1080 px for 1:1. Keep all cards the same ratio. Mixed ratios in a single Carousel create an inconsistent, jarring scroll experience.
Instagram integration (cross-platform specs)
Instagram feed ads in a Meta campaign require a minimum of 1080 x 1080 px. If you're running on both Facebook and Instagram, size up to the higher requirement. One resized asset covers both.

Step-by-Step. How to Resize Your Image
You have three options. Use Ads Manager's built-in crop tool, prepare your image before upload, or use Revise to handle everything automatically.
Using native Ads Manager tools
When you upload an image in Ads Manager, a crop tool appears for each placement. Select your placement, click "Edit Image", and drag the crop frame. This works for one image at one size. It gets slow fast when you have multiple placements or multiple creatives.
Preparing an image before upload
The faster manual approach. Start with a 1440 x 1440 px canvas for 1:1. Export as JPG or PNG under 30 MB. That covers Feed and Carousel. For Stories, build a separate 1080 x 1920 px asset with your safe zones marked out before you place any text.
Checking and adjusting with Revise
Upload your image to Coinis Revise. Select Smart Resize. Choose your target placements. Revise outputs correctly sized versions in seconds. No manual cropping and no quality guesswork.

Common Mistakes to Avoid
Small sizing errors cost real money in wasted impressions. These are the ones that come up most often.
Ignoring the safe zone for overlays
In Stories ads, the top 250 px and bottom 340 px are covered by Facebook's UI elements. Put your CTA or product shot in those zones and no one sees it. Build your Stories creatives with those boundaries in mind from the start.
Uploading low-resolution images
Images below 600 x 600 px get rejected at upload. Images that pass the minimum but fall short of the recommended resolution look blurry on retina displays. Always start at the recommended size.
Mismatching aspect ratios across placements
Facebook allows a 3% aspect ratio tolerance. Anything outside that range gets auto-cropped. A horizontal 1.91:1 image placed in a 4:5 slot will lose the top and bottom. Check every placement's aspect ratio before you publish.

Frequently Asked Questions
What is the best image size for a Facebook ad?
The recommended size for Facebook feed image ads is 1440 x 1440 px (1:1 ratio) or 1440 x 1800 px (4:5 ratio). These dimensions display sharply across devices. The minimum accepted is 600 x 600 px (1:1) or 600 x 750 px (4:5), but starting at the recommended resolution prevents blurry output on modern screens.
Can I use the same image for Facebook Feed and Stories?
Not without resizing. Feed ads use 1:1 or 4:5 ratios. Stories require 9:16 or 4:5. If you use a Feed image in a Stories placement without adjusting, Facebook will crop it automatically. Use Coinis Revise Smart Resize to generate both versions from one source image.
What file formats does Facebook accept for image ads?
Facebook accepts JPG and PNG for image ads. Maximum file size is 30 MB. PNG works best when you need sharp text edges or transparency. JPG at high quality is fine for most photo-based ad creatives.
What is the safe zone for Facebook Stories ads?
Facebook recommends keeping 250 px clear at the top and 340 px clear at the bottom of Stories ads. Facebook's UI elements, including profile names and CTA buttons, overlay those areas. Any text or key visuals placed there will be hidden from viewers.
