Paper Weight

Paper weight indicates the thickness of the paper stock used. Our papers are divided into two weight categories:

Text stock: Measured in pounds (usually noted lb. or #), these papers are most often used for inside pages.

Cover stock: Measured in points (usually noted pt.), these papers are most often used for cover pages.



Here are the paper weights PrintNinja offers, along with their common uses:

There are many different paper weight classifications beyond text and cover, such as bond, index, tag, and more, however text and cover are the ones PrintNinja uses.  When comparing domestic and international paper stocks, make sure you’re comparing both weight and type.  For example, 80# text is a very different paper than 80# cover.
