Choosing the correct basis weight for a printed piece can be challenging. The weight of the paper you choose can influence things like the thickness of your finished project, the amount of print show-through and the overall tactile feel. Because paper is available for purchase in a variety of sizes, finishes, colors, and weights, finding the perfect line can feel overwhelming!
What is Basis Weight?
The technical definition of basis weight (also known as paper weight) is the weight of a sheet of paper based on a basic size. The basis weight of paper equals the ream weight (500 sheets) of the basic size and is measured in pounds.
Let’s clarify with a simple rule of thumb: the lower the number in pounds, the lighter the paper. The higher the number in pounds, the heavier the paper.

Which Weight is the Best?
When choosing the best basis weight for your project, it’s important to think about what you’re going to be designing and printing. Lighter weight papers (like 50 lb. and 60 lb. text) are better suited for the interior pages of projects with minimal photos and mostly type. Heavier weight text papers (70 lb., 80 lb. and 100 lb.) are best for projects featuring more graphics and print coverage.
Lighter-weight cover papers (like 65 lb., 80 lb. and 100 lb.) excel when used in direct mail, small, folded brochures or as the covers of booklets. Heavier-weight cover papers (110 lb., 130 lb. and 160 lb.) convey luxury and provide stability to projects like business cards, invitations and pocket folders.
The Weight I Want Isn’t Available! What Do I Do?
Paper availability can fluctuate, so understanding and being able to compare the differences in basis weights and types of paper is often the key to selecting the best option for your project.
Did you know that if a weight isn’t available in one type of paper, there is likely an equivalent in another type? For example, 20 lb. copy paper is very similar in weight to 50 lb. text paper.
