Instagram just announced that it will go from 640×640 picture posts now to 1080 x 1080 picture posts.
This is most likely attributed to mobile hardware improvements since 2010 and camera phones now take excellent pictures. So to meet the new uploads and higher quality standards, Instagram changed their programming to allow users to include more.
So what does all that gobbledygook actually mean for the Instagrammer?
Before you could only post this type of image with marginal clarity (640 resolution).
Now, you can post this with better quality and better clarity (1080 resolution).
Bigger picture at a standard 1080 resolution, better clarity, and a much better story platform for your audience.
Picture border? Still square.
Time is short, so Gram good stuff.
