Profile photo
If you want your followers to easily identify your brand, you should adopt a high-quality representative photo for your profile picture, so people can easily recognize you. Even though the size is 280 pixels x 280 pixels, keep in mind that Pinterest will crop your profile picture and display it as a circle.
Pins
The best visuals you can use on Pinterest are the 2:3 ratio vertical ones. Visuals like stories or infographics are the rockstars of Pinterest.
Board cover
Your Pinterest board cover is very important. Make sure you’re designing good looking board covers using the right size: 600 pixels x 600 pixels, so people will pin your boards and start following you.
