How to use this tool

  1. Enter width, height, print width, print height.
  2. Use consistent units shown beside each input. Run the calculation and review the assumptions below.

Try this example

{
  "width": 6000,
  "height": 4000,
  "print_width": 8,
  "print_height": 10
}

Accuracy and scope

Orientation used exactly as entered; crops only, no resampling. Different from fit-with-padding output sizing.
