Facebook ad sizes in 2026 and what each placement takes

Three ratios cover most Facebook and Instagram ad placements: 4:5 for the feeds, 9:16 for Stories and Reels, and 1:1 for Marketplace. Meta asks for 1440 x 1800 pixels at 4:5 and 1440 x 2560 pixels at 9:16.

Below are each placement's ratio and size, the places where Meta's own pages contradict each other, and what Ads Manager cuts when one picture has to fill them all.

Facebook ad image size by placement

For a single image, make it 4:5 at 1440 x 1800 pixels for Facebook Feed and Instagram Feed, and 9:16 at 1440 x 2560 pixels for Facebook Stories, Instagram Stories and Instagram Reels, which are the sizes Meta's ads guide gives for those five placements.

Each row is one page of the guide, read on 13 October 2026.

Facebook Reels, Instagram Explore, Messenger Stories, WhatsApp Status, Threads and Audience Network are left out, because their sizes were not on the Meta pages this post was written from. Confirm them in Ads Manager before you build for them.

File type, file size and tolerance

The guide lists JPG or PNG files of up to 30 MB for the feeds, Stories, Reels, Marketplace and Search Results. The smallest width is 600 pixels on Facebook Feed and Search Results, and 500 on Instagram Feed and the vertical placements.

It also lists an aspect ratio tolerance, 3% on Facebook Feed and Search Results and 1% on Instagram Feed and the vertical placements, so export to the exact ratio.

Where to keep text in a vertical ad

The profile icon and the call-to-action button sit on top of a Story or a Reel. For image ads there, Meta's ads guide suggests leaving roughly 14% of the top, 35% of the bottom and 6% on each side free of text, logos and other key elements. On a 1440 x 2560 file that leaves a box about 1267 pixels wide and 1306 tall, close to a square, and the product and the words have to fit inside it.

Meta's safe zone article adds three cases. On screens taller than 9:16 the ad may be zoomed to fill the screen, which can crop what sits outside the safe zone, or shown at 9:16 on a black background. A Reels ad with a disclaimer should keep the bottom 40% clear. And Instagram Feed ads at 1:1 or 4:5 should keep the bottom and side edges clear.

In Ads Manager you can switch on a Safe zone guardrail. The safe zone is the area inside the yellow overlay it draws on your ad.

Carousel and video shapes

Facebook Feed carousels ask for 1:1. Instagram Feed carousels ask for 4:5 when every card is an image and 1:1 when any card is a video, both at 1080 x 1080 pixels or more. Instagram Stories carousels ask for 9:16 at 1080 x 1920 or more.

Video follows the same shapes, with one difference. Instagram Feed video is 9:16 at 1080 x 1920 pixels, where its images are 4:5. Facebook Feed video is 4:5 at 1440 x 1800, and video in Stories and Instagram Reels is 9:16 at 1440 x 2560. On desktop Facebook Feed, Meta's table of supported ratios says video is shown at 1:1, which may leave black bars either side.

What gets cut when one picture goes everywhere

Upload one shape and Ads Manager fits it to the rest. Meta's article on aspect ratios says your media is adjusted automatically to fit more placements, and that when you do not supply every shape the system helps fill the gaps with options such as padding, media expansion, cropping and AI-enabled features.

If it crops, the arithmetic is plain. A 4:5 picture cut to 9:16 loses about 30% of its width, and a square one about 44%. A 9:16 picture cut to 4:5 loses about 30% of its height, the top and bottom of your Story. Those sums come from the ratios, not from Meta, whose pages do not say which adjustment a given picture gets.

So make the shapes yourself where a placement matters. Meta's advice is to upload a 9:16 asset if Stories matters to the campaign, to review the auto-generated crops before publishing, and to switch off any adjustment you don't want. Meta notes that media customisation may not be available to you at this time, so what you see in Ads Manager can differ.

Looking at the ad in each size you plan to run is the last of the five checks before an AI ad runs.

A picture in four sizes is still one ad. Meta asks for ads that differ in reason to buy and in picture, so sizes serve the placements and add no variety.

Where Meta's own pages disagree

Meta's pages do not always agree. Each item below says which number to use.

• Instagram Feed images: the ads guide and Meta's table of supported ratios recommend 4:5, and the aspect ratio article recommends 1:1. All three accept 4:5.
• Stories size: the ads guide says 1440 x 2560 for images, and the Instagram Stories design requirements recommend 1080 x 1920. Both are 9:16, and Instagram Stories accepts every feed shape.
• The bottom band: the image pages for Stories and Reels say 35%, and the Facebook Stories video page says 20%. Keep 35%.
• Right column: the guide says 1:1, and the table of supported ratios recommends 1.91:1 and accepts 1:1. The format is desktop-only, so 1:1 is the safe pick.
• Carousel cards: the aspect ratio article says 4:5 is only available for Advantage+ catalog ads, and the guide lists 4:5 for Instagram Feed image carousels. For a feed carousel, 1:1 is the one ratio no page argues with.

Getting every size without redrawing

Making one ad in 4:5, 9:16 and 1:1 by hand means three exports, each checked against the safe zone. Nomi resizes an ad into the shapes you run. A resize keeps the words and changes the frame, and it arrives beside the original, so the version you approved is still there. A tall story or reel keeps the text and the call to action out of the bands the platform covers with its own buttons.
