Ads appear inside a square browse grid, so 1:1 sits most naturally; 4:5 is accepted. This placement is bundled into most Advantage+ and automatic-placement setups.

How to get Facebook Marketplace right

Design it right

Facebook Marketplace ads appear inside a square browse grid, so a 1:1 creative at 1080 x 1080 sits most naturally there - it fills its grid cell without odd cropping. A 4:5 file is accepted too, and because Marketplace is almost always delivered as part of an automatic or Advantage+ placement set rather than selected on its own, the practical move is to make sure your set includes a square or portrait cut so Marketplace has something clean to show.

⚠️

The common mistake

The common issue with Marketplace is not a dedicated design problem but neglect: teams optimize the 4:5 Feed and 9:16 Stories cuts and forget that automatic placements will also drop the ad into this square grid. If your only files are 9:16, Marketplace shows a cropped or padded version. Including a 1:1 (or letting a 4:5 stand in) keeps this placement looking intentional. Both image and video run here, up to the standard Meta limits - 30 MB images, 4 GB video.

Check your creative against Facebook Marketplace

Drop your files into the free creative validator - it reads each file's dimensions in your browser, tells you which placements it covers, and flags the aspect ratio your set is missing. For a single file, the aspect ratio checker gives a per-placement verdict.

Facebook Marketplace FAQ

What is the best aspect ratio for Marketplace ads?
1:1 (1080 x 1080). Marketplace is a square browse grid, so a square creative fills its cell cleanly. 4:5 is also accepted and works if that is the master you already have.
Do I need a separate creative for Marketplace?
Usually not a dedicated one, but you do need a square or portrait cut in your set. Marketplace comes bundled in automatic and Advantage+ placements, so if you only supply 9:16, it shows a cropped version.
Can I run video on Marketplace?
Yes. Marketplace accepts both image and video up to the standard Meta limits - 30 MB for images, 4 GB for video in MP4 or MOV. A 1:1 video fills the grid cell best.
Why does my Marketplace ad look cropped?
Because your set has no square or 4:5 file and Meta is squeezing a vertical cut into a square slot. Add a 1:1 (1080 x 1080) so Marketplace has a creative built for its shape.

Other placement specs

One concept, every ratio, one ad

Once each concept has its 4:5 and 9:16 cuts, uplads reads the placement in every filename and merges them into a single multi-placement ad - the right cut in each surface - across a whole bulk launch.
