Walmart Marketplace product image requirements

Walmart Marketplace requires product images on a white background, with the product filling at least 75% of the frame, at minimum 1000 pixels on the longest side (2200 px recommended). Walmart's image ranking signal weighs structured metadata (alt text, captions) more heavily than other marketplaces.

Recommended

What top sellers do on top of the rules.

  • Ship 2200×2200 to enable Walmart's zoom feature.
  • Use accurate alt text — Walmart's search ranking reads it.
  • Make sure AI-generated images accurately represent the SKU; Walmart can act on listings whose images misrepresent the product.
  • Use lifestyle and scale slots for categories where size or context matters (furniture, electronics, apparel).
