Paper Basis Weights

Basis Weight is the weight of a sheet of paper based on standard size.

Paper types are categorized by their base size in the U.S.

These base sizes are used to calculate a paper's basis weight. The basis weight equals the ream (500 sheet) weight of the base size, hence the term basis weight. Because the starting base size is not the same between paper types, the basis weights do not correspond directly (80 Text is much lighter than 80 Cover).

Neenah offers sheets in a range of weights so you can find the perfect paper for your project.

Below is a paper weight chart that provides the equivalent basis weights between paper types as well as the corresponding g/m².
