Here’s the ultimate guide to creating social media imagery effectively in 2016, all in the same place.
Opengraph — why so many images?
Firstly, a great post by Garrett Heath at Rackspace that I’ve been using for a long time. It proposes a single 1600 x 800 image with safe areas that will work as opengraph images for unfurling on all the major social media channels — Facebook, LinkedIn, Twitter, and Google+. One image to rule them all, indeed (correct me if I’m wrong here, please).
Dimensions — how wide, how high
Next up, the ultimate cheat sheet infographic from Jamie Spencer for image dimensions across Facebook, Twitter, Google+, Instagram, Pinterest, Tumblr, LinkedIn and YouTube. If you’re creating a profile on any of these, this should be your first port of call. Until they change, of course.
PSD Approval Mockups
This leads me onto the last (but by no means least) link, you’ll be wanting some mockup PSD templates to demonstrate your great images. There are a bunch of sites out there with downloadable PSDs (this one from everyinteraction.com is pretty good), but the best one I’ve found is actually a plugin for Photoshop called Social Kit Pro. It downloads new versions when a template (Facebook, Twitter, Google+, LinkedIn, VKontakte, Instagram, YouTube and Dribbble) is updated, for a single fee of $39.99 (£28).
