What is the best product image size for Shopify in 2026?
Shopify recommends uploading product images at 2048×2048 pixels in a square (1:1) format. This size enables Shopify's built-in image zoom feature on desktop, displays sharply on Retina screens, and keeps file sizes manageable. Use a consistent square ratio across your entire product catalogue so collection grids always look uniform. Keep files under 300 KB by compressing with WebP or JPEG at quality 80–85.
