How is the weight of paper determined?

Answer 1

The basic weight of a paper is based on the fixed weight of 500 sheets measured in pounds. The weight is also determined by each particular paper's "basic sheet size." For example, a pack of 500 sheets of 8 ½"-x-11" letter paper at its lightest weight may be 20 pounds heavier than a heavier type of this paper, which may be up to 25 pounds. In reference to art papers, the weight will jump considerably. For example, a watercolor paper's average size is 22" x 30", reaching to 300 pounds at its heaviest weight. This weight formula can be misleading. For example, people are known to ask for a 29"-x-41" 300-lb sheet of watercolor paper. Because of the larger size the paper is actually closer to 550 pounds. Outside of the United States metric is used. The formula here is more accurate: GSM means grams per square meter.

Answer 2

Weighing paper has two functions: first, it keeps whatever you're weighing from gunking up the balance pan, and second, weighing paper is generally very non-sticky, making it easier to transfer the full weighed amount to the reaction vessel (or whatever).

Answer:

In business the weight of paper is important:

• Different weights of paper cost different amounts, spending money for high weight paper in copiers or similar equipment is a waste.
• A large document on heavy paper costs more to mail than one on lighter stock.
• In published mail outs and letters to other firms the weight of a paper is an indication of the value of the correspondence. An important letter on flimsy paper seems less important.
• Different weights of paper take different printing methods differently. You can't use wet inks on porous or thin paper.
• Heavier papers are more durable.
• Heavier papers usually contain more clay and fillers and can look better.

Answer 3

Paper comes in differing sized sheets or may be sold in big roles that only machines can lift.

There are also differing qualities of paper as discussed in the related link below.

Your question is therefore too simplistic for the provision of a simple answer.
