Follow their instructions on how to crop and resize your profile picture and cover image using their template. But here are a few things to note:
- Make sure your profile image is clear when it’s shrunk to 32×32 pixels, since this is the size your profile image will appear at throughout your Facebook page (for example, next to any status updates you post).
- Your cover photo should be uploaded at a size of 851×315 pixels (which is the same size it will be displayed on your Facebook page).
- Your profile image should be uploaded at a size of 180×180 pixels (but it will be displayed as 160×160 pixels on your Facebook page).
