> Quick answer: Facebook Feed ads work best at 1200 x 628 px (1.91:1) or 1080 x 1080 px (1:1). Stories and Reels need 1080 x 1920 px at 9:16. Keep text under 20% of the image area. Coinis Revise resizes any image for any placement with one click.
Getting image sizes wrong costs you reach. Meta crops or stretches off-spec images, and your ad looks broken before anyone clicks.
Why Image Resizing Matters for Facebook Ads
Correct dimensions keep your creative sharp across every placement.
Placement compatibility and rendering
Meta serves ads across Feed, Stories, Reels, and more. Each placement has a specific aspect ratio. Upload the wrong size and Meta auto-crops the image. Key elements get cut without warning.
Avoiding cropping and distortion
A stretched or squished image signals low quality instantly. A cropped logo or a face cut in half kills trust before the viewer reads your headline. Getting dimensions right is the cheapest creative fix you can make.
Best practice performance (aspect ratio standards)
Per Meta's Ads Guide, supported aspect ratios range from 1.91:1 to 4:5. Meta applies a 3% tolerance, so images don't need to be pixel-perfect. But the closer you stay to the target ratio, the cleaner the render.
Recommended Image Sizes for Facebook Placements
These specs cover every major Meta placement.
Facebook Feed dimensions (1200 x 628 px, 1080 x 1080 px)
Facebook Feed works best at 1200 x 628 pixels (1.91:1 landscape) or 1080 x 1080 pixels (1:1 square). Square tends to take up more vertical space in the feed. That usually means more visibility.
Instagram Stories dimensions (1080 x 1920 px, 9:16 ratio)
Per the Meta Business Help Center, Stories ads should use 1080 x 1920 pixels at a 9:16 ratio. This fills the full screen. Feed-sized images render with black bars, which hurts the viewing experience.
Instagram Reels dimensions (9:16 or 1:1 variants)
Reels ads support 9:16 vertical (1080 x 1920 px) and 1:1 square. Vertical fills the screen completely. For most products, vertical outperforms square in Reels placements.
Minimum requirements (600px width, file size/type)
Minimum image width is 600 pixels. Minimum height is 600 px for a 1:1 ratio or 750 px for a 4:5 ratio. Max file size is 30MB. Meta accepts JPG and PNG files only.
How to Resize Images for Facebook Ads
Five steps cover the full process from source image to ready-to-upload creative.
Step 1: Determine your target placement
Pick the placement before you resize anything. Feed, Stories, and Reels each need different dimensions. Skipping this step means resizing twice.
Step 2: Calculate or select the right aspect ratio
Match the image to the placement's aspect ratio. For Feed, target 1.91:1 or 1:1. For Stories and Reels, target 9:16. The 3% tolerance gives a small buffer, but don't rely on it.
Step 3: Use a resizing tool (browser, design software, or AI-powered editor)
Any image editor can crop and resize. AI-powered tools go further. Coinis Revise's Smart Resize identifies the focal point in your image and crops intelligently. No manual crop handles to drag.
Step 4: Check text overlay coverage (max 20%)
Per the Meta Business Help Center, images with more than 20% text coverage may face delivery penalties. Meta can limit reach on text-heavy creatives. Keep text tight and purposeful.
Step 5: Export in correct format (JPG or PNG)
Save as JPG or PNG. Stay under 30MB. JPG produces smaller file sizes. PNG preserves transparency for designs that need it.
Common Resizing Mistakes to Avoid
Each of these mistakes appears in live campaigns more often than it should.
Over-stretching or squishing the image
Never force a landscape image into a square slot by stretching. Always crop. Stretched images look distorted and unprofessional.
Ignoring text overlay guidelines
Text covering more than 20% of the image area can limit ad delivery. Meta may reduce reach without any notification.
Using low-resolution source images
Starting from a 400 px source and scaling up produces blurry ads. Always work from the highest-resolution file you have. Coinis Revise's AI Upscale can recover detail from lower-resolution sources.
Not accounting for aspect ratio tolerance (3%)
The 3% tolerance is not a free pass. An image at 1.5:1 won't render cleanly in a 1.91:1 placement. Stay as close to the target ratio as possible.
Smart Resize: Automate Your Image Resizing
Manual resizing works. Doing it for five placements at once takes real time.
How Revise's Smart Resize works
Upload your source image in Coinis Revise. Select your target placement or aspect ratio. Smart Resize adapts the crop automatically, keeping the focal point centered and the composition intact.
Benefits of AI-powered resizing over manual tools
You skip the back-and-forth of dragging crop handles in a design tool. Smart Resize produces Feed, Stories, and Reels versions in seconds. Same source image, multiple ready placements.
Generating fresh creatives with Image Ads
If your source image isn't strong, skip the resizing problem entirely. Coinis's Image Ads workflow generates placement-ready creatives from a product URL. Every output is correctly sized from the start. No resizing needed.

Frequently Asked Questions
What is the best image size for a Facebook Feed ad?
The best sizes for Facebook Feed ads are 1200 x 628 pixels (1.91:1 landscape) or 1080 x 1080 pixels (1:1 square). Square often gets more vertical screen space in the feed. Both are supported per Meta's Ads Guide.
Can I use the same image for Facebook Feed and Instagram Stories?
Not without resizing. Feed uses a 1.91:1 or 1:1 ratio. Stories require a 9:16 ratio (1080 x 1920 px). Using a Feed image in Stories will show black bars. You need a separate resized version for each placement.
How much text can I put on a Facebook ad image?
Per the Meta Business Help Center, text should cover no more than 20% of the image area. Images with more text may see reduced delivery and limited reach.
What file formats does Meta accept for image ads?
Meta accepts JPG and PNG files for image ads. Maximum file size is 30MB. JPG is recommended for smaller file sizes. PNG works best when your design requires transparency.
