Calculate dimensions and areas using the standard 4:3 aspect ratio, commonly used in video, displays, and traditional media formats
Learn how to use the 4:3 ratio calculator and its applications
The 4:3 ratio (also known as 1.33:1) is an aspect ratio where the width is 4 units and the height is 3 units. It was the standard for television screens and computer monitors before the adoption of widescreen formats.
If you need to calculate the area of a traditional TV screen that has dimensions of 32 inches in length and 24 inches in width, enter 32 in the length field and 24 in the width field to determine that the area is 768 square inches.
