With all the recent changes to our favorite (or not so favorite) social networks with Facebook covers, Twitter header images and YouTube branded channels, businesses have had to redesign their images and rethink of how they represent themselves visually online.

This gave way to a lot of new creative campaigns on Facebook, Google+ and Pinterest but is has led to a lot of social media managers scrambling to get the images just right.

Earlier this month LunaMetrics released an updated version of their widely popular Social Media Sizing cheat sheet with image and video sizes for Facebook, Twitter, Google+, YouTube, LinkedIn and Pinterest. Though I bookmarked it, I thought it was actually too valuable a resource to keep to myself.

So before you post your next picture or change up your profile image, take a look at this handy cheat sheet and bookmark it for yourself.
