Quick Answer
Divide the stack thickness by the number of sheets to get one-sheet thickness, or multiply a sheet thickness by the sheet count to get a stack.
How to Calculate Paper Thickness
- Choose whether you want a sheet thickness or a stack thickness.
- Enter the measured thickness value and select its unit.
- Enter the number of sheets in the stack.
- Read the result in millimeters, inches, and points.
Formula
Sheet thickness = stack thickness / sheet count
Stack thickness = sheet thickness x sheet count
Worked Examples
Example 1: 10 mm stack / 100 sheets = 0.10 mm per sheet.
Example 2: 0.004 in per sheet x 250 sheets = 1.0 in stack.
Example 3: 12 points per sheet x 50 sheets = 600 points, or 0.6 in.
