Marketplace image sizes at a glance

Every major marketplace sets a minimum and a size that lets shoppers zoom. From their own guidance:

  • Amazon — 500 to 10,000 px on the longest side; over 1,000 px is preferred so customers can zoom, and images should have no pixelation or jagged edges [1].
  • Shopify — up to 5000 × 5000 px (25 MP) and under 20 MB; 2048 × 2048 px usually displays best for square images [2].
  • eBay — at least one photo 500 px on the longest side, no added borders, text or watermarks [3]; about 1600 × 1600 px recommended, up to 24 photos of 12 MB each [4].
  • Google Merchant Center — at least 500 × 500 px for all products from 31 January 2027, about 1500 × 1500 px or larger recommended, up to 64 MP and 16 MB [5].
