What is the 4:3 aspect ratio?

4:3 is 4 units wide for every 3 units tall, a decimal ratio of 1.333. It was the shape of standard-definition television and early computer monitors, and it is still used by most smartphone camera sensors, many compact cameras and iPad screens.

height = width × 3 ÷ 4
width = height × 4 ÷ 3
