What matters

Poshmark Listing Photo dimensions at a glance

Poshmark listings display in a square grid at 1200×1200. The cover photo competes directly with hundreds of other listings in search and feed results.

Poshmark is visual-first social commerce. A clear, bright cover photo is the single biggest factor in whether shoppers tap on your listing.

Dark, cluttered, or off-ratio photos look amateur in the grid and get scrolled past. Poshmark's algorithm may also favor better-quality images.

Best practices

Use the crop intentionally

  • Use bright, even lighting — natural daylight works best.
  • Show the full item clearly against a clean background.
  • Style flat-lays or mannequin shots perform better than hanger photos.
