GSM to Thickness Calculator
Provides an approximate paper thickness estimate from its GSM rating.
Lilu Baba's GSM to Thickness Calculator estimates paper caliper (thickness) from GSM and an assumed density, since GSM alone measures weight, not thickness.
How to use this calculator
- Enter the paper's GSM rating.
- Enter its density (0.7-0.9 g/cm³ is typical for office paper).
- Estimated thickness updates instantly.

GSM to Thickness Calculator — frequently asked questions
Two papers with the same GSM can have different thicknesses if their density (fiber composition and compression) differs — this estimate assumes a typical density.
Standard office/printer paper is typically around 0.7-0.9 g/cm³; check your paper's specification sheet for an exact value if available.
