Understanding paperweights is not an easy task. Over the years, we have educated our customers and helped them make the best choices in paper. The table below was designed to try and simplify the different terms you may hear in association with paperweight. The term paperweight, and number corresponding with each weight, refers to the thickness and sturdiness of the paper, not the actual weight of the sheet. This is why, sometimes, the same “weight” paper may be referred to as two different things. For instance, regular everyday copy paper is most commonly referred to as a “20 lb. bond” but is other times referred to as a “50 lb. text weight.” To eliminate as much confusion as possible, we have chosen GSM as our conversion reference point because it is a definite and universal measure of the paper. GSM stands for grams per square meter, which is the actual weight of the sheet.

*Please remember that the greater the “lb” associated with a paper not always determines that it is a thicker sheet. Notice that the 67lb Vellum Bristol has a lower gsm than a 65lb cover because they are two different categories of cardstocks and are scaled differently.
