Notes

Formula for inch to cm conversion

The measurements above are an approximate of the final sizes in cm.

If you want an accurate measurement, multiply the inches by 25.4 to get the precise size in cm.

For example:
12 inches = 12 * 25.4 = 305 mm

Formula for resolution requirements

The resolution requirements quoted are the minimum requirements needed. They are calculated at 72DPI.

If you want the best result, or if you are a professional photographer, we'd recommend at least 200 and ideally 300 DPI.

To calculate the accurate resolution requirement, multiply the inches by the DPI.

For example: 12 inches at 300 DPI = 12 * 300 = 3600px
