Product-media limits and the square recommendation
Shopify product images should remain under 20 MB, no larger than 5,000 × 5,000, and no more than 25 megapixels. The familiar 2,048 × 2,048 recommendation applies to square product imagery, not every proportional photograph.
- A 2,048 × 1,365 proportional image is valid when it meets upload limits.
- A square canvas remains an optional catalog choice.
Consistency across a storefront
Matching aspect ratios can make product grids feel more consistent, but that is a merchandising decision rather than a universal upload rule. Shopify may optimize delivery format and size for shoppers after upload.
- Watch file size as well as dimensions.
- Review theme crops before standardizing an entire catalog.
