3:4 aspect ratio
A 4:3 frame turned upright — how a phone photo comes out when the phone is held vertically, and how a tablet reads in portrait. 4 common sizes from 768×1024 to 3024×4032, each checked to reduce to 3:4.

The math
3:4 is 0.75:1: the width is 3/4 times the height. To get a height from a width, multiply by 4 and divide by 3 — 1080 × 4 ÷ 3 = 1440. That is the 1080×1440 in the table. The calculator above does the same for any width or height, and gives the ratio of any size in the other mode.
