Paper Thickness Calculator

Paper Thickness Calculator

Whether you are a print designer, packaging engineer, or hobbyist, knowing the thickness of a single sheet of paper is essential for choosing the right stock. This paper thickness calculator works two ways: enter a stack thickness and sheet count to find the thickness per sheet, or enter a per-sheet thickness and sheet count to find the total stack thickness. Results are displayed in millimetres, inches, and typographic points simultaneously, so you always have the unit you need.

Use "Sheet thickness from stack" mode when you have a ream or stack of paper and want to know how thick each individual sheet is — simply measure the stack height and enter the number of sheets. Use "Stack thickness from sheet" mode when you know the caliper of a single sheet and need to estimate the total height for a print run or binding project. All conversions between mm, inches, and points are handled automatically.
