When you add a friend to your limited profile list on Facebook, he becomes unable to see content you've restricted from members of the list. The privacy settings Facebook rolled out in August 2011 restrict all content you post from members of the limited profile list.
In choosing a profile picture, choose something that will work well at small sizes. While the one thatâs displayed with the cover photo is a reasonable size, the same profile picture is also used much smaller elsewhere on Facebook like next to any comments you post. Also remember that your profile picture is always public (as is your cover photo). Itâs always displayed as a square. You can upload a rectangular image, but it will be cropped to a square shape. It will be displayed at 170px by 170px on computers and 128px by 128px on smartphones.
