Target: 3:2Understanding the 3:2 Aspect Ratio Format
The 3:2 aspect ratio (1.5:1) was introduced by Oskar Barnack for 35mm film negatives and remains the physical native aspect ratio of Full Frame and APS-C DSLR & mirrorless digital camera sensors.
Mathematical Formula & Calculation Mechanics
To calculate 3:2 dimensions, multiply height by 1.5 to solve width, or divide width by 1.5 to solve height. E.g., for 6000x4000, GCD is 2000 (6000/2000 = 3, 4000/2000 = 2).
