Mercari photo size and rules: 12 photos, light and background

Updated · 2 min read

Short answer

Mercari's help center lets you add up to 12 photos per listing and recommends natural light and a plain background. It does not state a pixel size, file type or shape on that page, so there is no exact size to hit. Keep photos sharp and put your best one first.

The Mercari help page we read does not mention size, file format, aspect ratio, or rules on watermarks and text. Third-party guides claim a square-only rule; we could not confirm it on a Mercari page, so treat it as unverified.

What Mercari says

  • Number: up to 12 photos per listing.
  • Light: take as many photos as possible in natural light, to show the item's exact colour.
  • Background: a plain background avoids distraction.
  • Flaws and angles: show any defects and every side of the item.
  • Order: the first photo is the one shoppers see first, and you can rearrange the photos at any time.

How to prepare Mercari photos

  1. 01Photograph the item in daylight against a plain surface, from every side, and add close-ups of any flaws.
  2. 02Pick your clearest photo as the first one.
  3. 03If you edit, keep the originals large and crop only what you need. See does cropping reduce image quality.
  4. 04If you want all photos in one shape, a square is the safe choice. See how to crop a photo to a square.

SizeSpec has no Mercari preset because Mercari publishes no size to base one on. For the method that works on any photo set, see how to crop multiple photos at once.

Selling online? Do a whole batch at once

SizeSpec crops and resizes a batch of product photos to the size Mercari asks for and gives you one ZIP. It crops from the centre or pads the image on white, and it works in your browser, so your files are never uploaded. It does not offer free-hand cropping of a single picture.
