I spotted this surprisingly useful infographic yesterday, over at Visually. It should come in handy for anybody who creates image-based content to add to their social profiles.
Five of the biggest social media platforms are covered, and it will help you to understand the various sizes needed for your profile pictures, cover images, backgrounds, and so on.
if you're anything like me you'll be yearning for some kind of cross-site standardisation in the future. For example, all of the profile pictures are different sizes, and one is a different shape. We can but dream!
Anyhow, it should make for a handy cut-out-and-keep guide for you...
