How thick is a single, 8.5" x 11" sheet of standard printer paper?

I saw this article on Cha Chathat said it was about nine millimeters, but that CAN'T be right!

Standard printer paper is approximately .1mm thick. For paper with a basis weight of 20 lbs, which is what I use in my printer, has a thickness of .097 mm. So you are right the Cha Cha answer does appear to be way off the mark.

For fun, I did a quick check. I measured a ream of unopened paper to have a height of about 4.6 cm. The ream contains 500 sheets of paper with a paper wrapping on the top and the bottom. Lets assume the paper wrapping in the same thickness as the actual printer paper. This would mean the ream has 502 sheets of paper in it. At a height of 4.6 cm or 46 mm, this would mean each piece of paper has a height of .0916 mm. Which for seems close enough to the wikipedia value for me to accept them both.

A mil is not short for millimeter. A mil is one thousand of an inch or 0.001"

Right Slider. The article says the thickness of paper is about 9 mil, not 9 millimeters. Nine mil is correct.

Three shall be the number thou shalt count, and the number of the counting shall be three. Four shalt thou not count, neither count thou two, excepting that thou then proceed to three. Five is right out. Once the number three, being the third number, be reached, then lobbest thou thy Holy Hand Grenade of Antioch towards thy foe, who, being naughty in my sight, shall snuff it. -MP

What you do is you get a ream of paper, take note how many sheets are in the ream and then measure the thickness and divide by the number of sheets.
