The maximum image size for a listing image is 5 MB and the maximum width is 732px wide and 800px tall. If the image is bigger than 732px, we proportionally reduce it to that size. If the final size is still taller than 800px then we reduce the height proportionally until it reaches 800px. In all cases, there is no cropping involved for listing images. Only JPG and PNG filetypes can be uploaded to Apartment Therapy Marketplace.
Thumbnail images are standardized at 190x190px which does require automated cropping, unless the uploaded image is a square. To crop the image, our system takes the shortest size and resizes it centered until it reaches 190px. The longer side is cropped to maintain the 190x190px size.
