The first thing your followers see when they visit your Pinterest page is your collection of boards. This means Pinterest allows you to upload longer images since only the width is fixed.

The optimal image dimension is 735 x 1102 px pixels, however, pins will be displayed with a width of 238 pixels with scaled height. Pinterest’s interface is portrait-oriented so vertical pins with a 2:3 ratio are best. The recommended size for your image should be a 280 x 280 pixels square which will be cropped and displayed as a circle. Therefore your profile photo is the primary means for your followers to identify and recognize you. The profile photo you use is particularly important because Pinterest has no header image. As a social platform, Pinterest is primarily a visual one, so it’s important that the images you use for your profile and for your posts are of the best possible quality. It’s as simple as typing in search queries and discovering images to “pin” and collect as a Pinterest “board” specific to that theme or subject. Users flock to Pinterest to find and share inspiration for a wide variety of topics such fashion, design, food and events.
