Aspect ratio is the proportional relationship between an image’s width and height. It describes the shape of an image rather than its absolute size.
Common aspect ratios include square, portrait, landscape, and platform-specific formats used in ecommerce, marketplaces, ads, and social media. Different ratios affect how a product is framed and displayed within a layout.
Aspect ratio is important because the same image may need to be adapted for different placements. A product image that works on a PDP may need a different ratio for a mobile interface, social post, or marketplace listing.
Choosing the right aspect ratio helps preserve product visibility and composition. If the ratio is poorly matched to the platform, key details may be cropped out or the image may appear awkward in the interface.
In the context of visual commerce, aspect ratio connects to image cropping, image resizing, platform-native product images, and cross-platform product images because product visuals often need to be reformatted for multiple environments.
