> Quick answer: Use 4:5 (1080x1350px) as your master creative. It covers Facebook Feed (mobile), Instagram Feed, and Stories. Add a 1.91:1 (1200x628px) variant for desktop Feed and Messenger, plus a 9:16 (1080x1920px) version for Reels to cover every placement.
Running one ad image across every placement without resizing gets it cropped, distorted, or rejected. This guide covers exact dimensions for each placement and a clear step-by-step workflow.

Why Resize Facebook Ads Across Placements
Each Meta placement renders a different shape. One untouched image cannot serve all of them.
Single image, multiple placements
A cross-platform campaign spans four or more aspect ratios at once. Feed, Stories, Reels, Messenger, and Carousel all expect different dimensions. Your base image needs variants for each.
Avoiding cropping and distortion
Meta auto-crops images that fall outside a placement's supported ratio. That can cut your headline in half or hide your product entirely. Resize proactively and you control the frame.
Maximizing mobile engagement
Most Facebook and Instagram usage is mobile. A 4:5 portrait fills far more vertical screen space than a 1.91:1 landscape banner. More screen space earns more attention.

Facebook & Instagram Placements and Their Dimensions
Per Meta's Ads Guide, supported ratios vary by placement. Use the specs below to avoid rejection or silent cropping.
Feed (desktop & mobile): 1.91:1 and 1:1 / 4:5
Facebook Feed supports three ratios. Use 1.91:1 (1200x628px) for desktop and link-based ads. Use 1:1 (1080x1080px) for square. Use 4:5 (1080x1350px) for mobile portrait. Note. 4:5 is not available for desktop-only placements.
Stories & Reels: 9:16 or 4:5
Instagram Stories and Reels render best at 9:16, up to 1440x2560px. Facebook Stories also accept 4:5 if you prefer a shorter vertical crop.
Messenger: 1200x628 recommended
Messenger ads render optimally at 1200x628px. That is the 1.91:1 landscape ratio. The same file you create for desktop Feed works here.
Carousels: 1:1 or 4:5
All carousel cards must share the same aspect ratio within a single carousel ad. Use 1:1 (1080x1080px) or 4:5 (1080x1350px). The minimum size per card is 1080x1080px.
The most versatile ratio: 4:5 (1080x1350px)
4:5 covers Facebook Feed (mobile), Instagram Feed, and Stories in one shot. It travels further than any other single ratio. Build your master creative here first.

Step-by-Step: How to Resize Your Facebook Ad
Step 1: Choose your master aspect ratio (4:5 recommended)
Start with a 1080x1350px canvas. Place your product, headline, and CTA inside the center 80% of the frame. This protects key content across all downstream crops.
Step 2: Export or prepare your base image
Export at full resolution. Per Meta's recommended minimum pixel requirements, the platform accepts images from 600x600px. Aim for 1080px on the shortest side for sharp rendering at every size.
Step 3: Create variants for desktop and mobile
Crop a 1:1 (1080x1080px) square from your 4:5 master. Then reframe a 1.91:1 (1200x628px) landscape version for desktop Feed and Messenger. For Stories and Reels, extend the canvas to 1080x1920px and fill the exposed background.
Step 4: Verify safe zones and text placement
Meta recommends leaving 250px clear at the top and 340px at the bottom of Feed ads. UI elements overlap those edges. Keep your text and CTA inside the protected center zone.
Step 5: Upload and assign to placements
In Meta Ads Manager, upload each variant separately. Use the placement preview tool to confirm every version looks correct. Assign each image to its matching placement group.

Common Resizing Challenges & Solutions
Text getting cut off in narrow placements
Text near the edges of a 4:5 canvas disappears in a 1:1 crop. Design all text and logos inside the center 80% of the frame from the start.
Loss of detail on smaller screens
Complex backgrounds lose clarity at smaller sizes. One strong hero visual performs better than a busy composition with multiple elements competing for attention.
Maintaining brand consistency
Colors, fonts, and logos must match across every variant. A consistent Brand Profile in Coinis keeps AI-generated copy and visual context on-brand at every size, across every placement.

Frequently Asked Questions
What is the best aspect ratio for Facebook ads across all placements?
4:5 (1080x1350px) is the most versatile ratio. It works across Facebook Feed (mobile), Instagram Feed, and Stories. Add a 1.91:1 (1200x628px) variant for desktop Feed and Messenger, and a 9:16 (1080x1920px) version for Reels to cover every placement.
What happens if I don't resize my Facebook ad for each placement?
Meta auto-crops images that fall outside a placement's supported aspect ratio. This can cut off your headline, product image, or CTA without warning. Creating properly sized variants for each placement keeps you in full control of the frame.
Can I use one image for both Facebook and Instagram ads?
Yes, but only if it matches the supported ratios for both platforms. A 4:5 (1080x1350px) image works on Facebook Feed (mobile) and Instagram Feed simultaneously. For Stories and Reels, you still need a separate 9:16 (1080x1920px) version.
What are the safe zone rules for Facebook Feed ads?
Per Meta's pixel requirements guidance, leave at least 250px clear at the top and 340px clear at the bottom of Feed ad images. UI elements overlap those edges. Place all critical text and CTAs inside the protected center area.
