# how thick is paper in mm 0.05 to 0.10 millimeters

• ### How thick is a piece of paper?

• Paper today, doesn’t only vary in its texture, size and color, but also in its caliper or in the other words thickness of a piece of paper expressed in thousandth of an inch. Although as I have already mentioned there are various types of paper, the average thickness of a regular copy paper ranges from 0.05 to 0.10 millimeters.

• ### What is the standard size of a grade of paper?

• Each group of the grade of paper is assigned a standard size that all weights are referred to. The basics of this standard are as follows: Bond has a standard size of 17 x 22 and this is the size that is measured for 500 sheets. If 500 sheets of this size weigh 20lbs., then the paper is classified as a 20lb. bond.

• ### What is the standard bond size for paper?

• The basics of this standard are as follows: Bond has a standard size of 17 x 22 and this is the size that is measured for 500 sheets. If 500 sheets of this size weigh 20lbs., then the paper is classified as a 20lb. bond. Heavier and lighter stocks will obviously be thicker or thinner than the 20lb.

• ### Why is the thickness of A4 paper 80 g/m2?

• The ratio of sides is such that the shape does not change when cutting in half to get 2x A1 from an A0. You could then work out the dimensions of an A4 piece of paper (involving the fourth root of 2) hence the thickness at 80 g/m2. All this is extremely useful if ever you need an extremely small but accurate weight.
