To achieve the best visual presentation for your product images on your app's product page, it is recommended to use images in portrait orientation.

Our aspect ratio will automatically fill the portrait orientation of a phone screen. This will ensure that the product images are optimally displayed and visually appealing to your app users - across all devices.

Consider using dimensions that align with typical phone screen ratios, such as 9:16 or 3:4, to maintain the intended display quality.
