Their new massively useful cheat sheet shows the pixel dimensions of just about every component on the major social networking sites. If you want your photos to look their best on your LinkedIn page or when reposting to Twitter, you might want to print this out and keep it by your desk.
I often cringe at the results Facebook comes up with by the time it is done compressing and resizing my photos, especially for profile pictures. I’m curious how much of a difference following these size guidelines will make.
