How to Calculate 3:2 Dimensions?

To maintain the 3:2 ratio manually, use the following formulas:

  • Height = Width × 0.6667
  • Width = Height × 1.5

Example: If your width is 1500 pixels → height = 1500 × 0.6667 = 1000 pixels.

Why Use the 3:2 Ratio?

The 3:2 aspect ratio is popular in photography as it matches the native format of many DSLR and mirrorless cameras. It provides a balanced composition and prints well on standard paper sizes like 6×4 inches or 12×8 inches.
