Image Size Resource
*The image size/pixels requirements on your sites may have an impact on the image quality. Images that are much smaller and fail to meet the minimum image submission requirements will result in blurry look. In some cases/on some sites, if you submit the images that are larger than the requirements, the photos will also look blurry as a result of image compression. Larger images may also slow down photos opening and your viewers may be impatient to wait even if just a few more seconds.
Recommends using 2048 x 2048 pixels for square product photos
At least 1000 pixel on either height or width
The recommended size for listing images is 2000px for the shortest side of the image, and a resolution of 72PPI. File < 1MB for smooth uploading.
The ideal size for square posts is 1080px by 1080px at a 1:1 aspect ratio.
For landscape posts, use an image that is 1080px by 566px, with an aspect ratio of 1.91:1.
Vertical images should be sized at 1080px by 1350px with a 4:5 aspect ratio
The API supports a maximum image dimension of 15,000 pixels (width + height in pixels). If your image is less than 1,000 pixels (width + height in pixels), a warning is provided but the picture is not rejected.
For the best zoom-in functionality, size your images so they are between 800-1600 pixels on the longest side.
Recommend using images that are between 1500 and 2500 pixels wide
A resolution of at least 3,000px on the shortest side of your picture
Regular E-Commerce sites and websites:
1000-3000 pixels, 96 DPI, or per your developer's suggestions
Image size (pixels) will match the desired final output size. (Additional print license fee may be applicable on large size posters, newspaper/magazine prints)
