About the 4:5 Aspect Ratio

The 4:5 ratio (0.8:1) is a tall portrait orientation that gives images slightly more vertical space than a square. It is Instagram's preferred ratio for portrait-oriented feed posts, displaying at 1080 x 1350 pixels.

In print photography, 4:5 corresponds to the classic 8x10 inch print size, one of the most popular formats for portraits, headshots, and wall art. Large format cameras (4x5 inch film) also use this ratio.
