Instagram is a photo and video-sharing social media application that was launched in 2010 by Kevin Systrom. The first prototype of Instagram was a web app called Burbn, which was inspired by Systrom's love of fine whiskeys and bourbons.

What size is an Instagram portrait? The ideal Instagram portrait aspect ratio is 4:5, and the ideal photo size is 1080px by 1350px. If you upload a larger portrait, say 4:6 or 9:16 (the size of a Snapchat photo), you'll be prompted to crop a portion of the photo out to fit.
