Yes indeed, we love social media just as much as the other guy and you can find us on most of the popular “must have” social channels. Images are a huge part of our social strategy, particularly as it is well known that a good image can really drive engagement. So how to optimize images (or maps) for a good social media strategy? Thanks to the good people at HootSuite, here’s a pretty handy list of the optimal dimensions for an image shared on top social networks:
Twitter – Images are forced to appear at 506×253 pixels but can be up to 1024×512 pixels.
Facebook – Images appear in the newsfeed within 470×394 pixel boxes but upload images with widths of 720, 960, or 2048 pixels for optimal quality
Google+ – the bigger the better, as long as images appear clearly at that 350px width. The maximum upload size is 2048×2048 pixels.
Pinterest images will appear at 238 pixels wide within feeds and 735 pixels wide when expanded
Photos uploaded to Instagram can be a maximum of 2048×2048 pixels
