The Perfect Facebook Ad Image Size Guide (2026)

In 2026, Facebook ads appear in over 20 different places. They are in the News Feed, in the right column, in Messenger, in Reels, in Stories, and even in games. If you try to upload just one square image for all of these, your ad is going to look terrible in half of them. To look professional, you need to command the screen real estate properly.

7 Proven Copywriting Frameworks That Turn Browsers Into Buyers

You don't need to make 20 different images. You really only need two core sizes to cover 95% of placements.

1. The Square (1:1 Ratio)

Dimensions: 1080 x 1080 pixels.
Where it goes: Facebook News Feed, Instagram Feed, Facebook Marketplace, Right Column.
Why it works: The square is the universal soldier. It takes up more vertical space on a phone than a landscape (widescreen) photo, giving you more room to sell. Never use landscape photos for ads on mobile; they look tiny.

2. The Vertical Full-Screen (9:16 Ratio)

Dimensions: 1080 x 1920 pixels.
Where it goes: Instagram Stories, Facebook Stories, Instagram Reels, Facebook Reels.
Why it works: This is the most immersive placement. It fills the entire phone screen. If you put a small square image here, it leaves ugly black bars at the top and bottom. You must design specifically for this tall format.

What About Landscape? (1.91:1)

You might see advice to make landscape images (1200 x 628). Honestly? You can usually skip this. Landscape images are mostly for desktop right-column ads, which get very little traffic compared to mobile. Focus your energy on Square and Vertical.

The 'Safe Zone'

For Vertical (9:16) ads, be careful not to put text at the very top or very bottom. The top is covered by the user's profile icon, and the bottom is covered by the 'Send Message' bar. Keep your text in the middle center of the screen to be safe.

Resizing Made Easy

Taking a square design and turning it into a tall Story design usually involves a lot of annoying dragging and resizing in Photoshop. Stirling does this with one click. You create the ad once, and it automatically generates the 1:1 and 9:16 versions for you.
