3:2 Aspect Ratio Calculator
Calculate dimensions for 3:2 photography format, the standard for DSLR cameras and 35mm film.
Calculate dimensions for 3:2 photography format, the standard for DSLR cameras and 35mm film.
The 3:2 aspect ratio is the standard for 35mm film photography and most DSLR/mirrorless cameras. This ratio originated from the dimensions of 35mm film frames (36mm x 24mm) and provides an ideal balance for both landscape and portrait photography. It also matches the dimensions of 4x6 inch prints perfectly.

3:2 comes from 35mm film, which has frame dimensions of 36mm x 24mm (a 3:2 ratio). When digital cameras were developed, they kept this ratio for compatibility with existing lenses and to match standard print sizes like 4x6 inches.
Standard 4x6 inch prints are an exact 3:2 match. For larger prints, 6x9, 8x12, 10x15, 12x18, and 20x30 inches all maintain the 3:2 ratio without any cropping needed.
3:2 is ideal for landscape photography and matches standard print sizes. 4:3 gives you more vertical space which can be useful for portraits or social media. Most cameras default to 3:2, but you can often change this in settings.
6000 x 4000 = 24,000,000 pixels = 24 megapixels. This is a common resolution for full-frame mirrorless cameras like the Sony A7 III and Canon EOS R.
3:2 captures more of the scene vertically while 16:9 is very wide and short. For most photography, 3:2 provides a better balance. 16:9 is optimized for video content, not still photography.
