The best size for a product image depends on your website layout, but common recommendations work well for most stores. For WooCommerce, a product image size of 800 × 800 pixels is ideal. This size keeps images sharp on desktop and mobile screens. Square images work best for consistent layouts and clean grids. Images should be high quality but not too heavy. A file size under 200 KB is recommended for faster loading. Use JPG format for photos and PNG for images needing transparency. Always use the same image size for all products.
