What 4:3 means
A 4:3 picture is four units wide for every three units high, so the width is one and a third times the height. 800 x 600 and 1600 x 1200 pixels are both 4:3. Turned on its side it is 3:4, which suits portrait pictures. Use Swap orientation to switch.

Cropping from other shapes
Going from 3:2, the shape of most DSLR photos, to 4:3 keeps the height and removes about 11 percent of the width. Going from 16:9 to 4:3 removes about 25 percent of the width. Choose the 4:3 box and place it over the part of the picture that matters most.
