Facebook ad sizes

A Facebook ad can show in several places, and each has its own shape. Meta’s ads guide gives exact figures for feed and Stories images; for the other placements, the sizes below come from Hootsuite’s and Sprout Social’s guides.

Every image can be a JPG or PNG of up to 30 MB. Meta lists an aspect ratio tolerance of 3% for feed images and 1% for Stories, so export at the exact shape rather than one that is merely close.

On a phone, a feed ad spans the width of the screen, so its shape decides how much of the screen it takes. At the same width, a 4:5 image is 25% taller than a square one and more than twice as tall as a 1.91:1 landscape. Meta’s feed guide names only 4:5, while third-party guides still offer square as well.

1440 × 1800 is the same shape as Instagram’s 1080 × 1350 portrait post, a third larger each way. One master file at the ad size scales down to 1080 × 1350 for organic posts without any cropping.

In the feed, the primary text sits above the image and the headline below it, next to the button. The picture doesn’t need to repeat either one; it needs one clear subject that reads at a glance.

Stories and Reels ads fill the screen at 9:16, with Facebook’s own labels and buttons laid over them. For Stories images, Meta’s ads guide says to leave roughly 14% of the top, 35% of the bottom and 6% of each side free of text, logos and other key elements.

On a 1440 × 2560 image, that is about 360 pixels at the top, 900 at the bottom and 86 at each side, leaving a clear area of roughly 1,270 × 1,300 pixels. Put the product, the headline and the logo there, and let the background run to the edges.

Tip: Running one campaign in the feed and in Stories? Make a separate 9:16 version for Stories and Reels instead of relying on one 4:5 image to fill a tall frame.

Meta’s ads guide pairs each placement with suggested text lengths. The text isn’t part of the image, but it decides how much the picture has to say by itself.

With the message carried by the text, the image can stick to one idea: the product, a face or a short line. Any words inside the image have to survive being shown at phone size, which is much smaller than they look on a design screen.

1. Start on the exact canvas: 1440 × 1800 for the feed, 1440 × 2560 for Stories and Reels, 1440 × 1440 for square placements.
2. Hold each file to its precise ratio, since Meta’s tolerance is 3% for the feed and 1% for Stories.
3. Save photos as high-quality JPGs and graphics with lettering as PNGs, each under 30 MB.
4. Export in sRGB, the standard colour space for the web.
5. Check every placement in the ad preview at phone size before publishing.

Treat the minimums, 600 pixels wide for the feed and 500 for Stories, as a floor rather than a target. Meta recommends 1,440-pixel-wide files, which leave detail to spare on sharp phone screens.
