3:2 Aspect Ratio & Photography Guide
The 3:2 aspect ratio (1.5:1) has been the gold standard of still photography since Oskar Barnack invented the 35mm format. It is the native sensor ratio for full-frame and APS-C mirrorless and DSLR cameras from Sony, Canon, Nikon, and Fujifilm.

Why 3:2 is the Photographer's Favorite Canvas
3:2 strikes a harmonious balance between the boxiness of 4:3 and the elongation of 16:9. It provides enough breathing room for portraits and landscapes while conforming directly to standard 4×6 inch darkroom print sizes without edge cropping.
Frequently Asked Questions about 3:2
