The 4:3 aspect ratio, also known as "standard" or "fullscreen," was the traditional format for older televisions and computer monitors. This ratio means that for every 4 units of width, there are 3 units of height.
It was the dominant format before the widespread adoption of widescreen displays and is still used in some professional video applications and retro gaming.

To calculate dimensions for a 4:3 aspect ratio:
Formula:
Height = Width × (3 ÷ 4)
Width = Height × (4 ÷ 3)
Example: For a width of 1024px, height = 1024 × (3 ÷ 4) = 768px
