Measure the thickness of multiple sheets (Say, ten or twenty) then divide the answer by the number of sheets to get the thickness of a single sheet.
3 Dimensions: Length, Width & Thickness
Depends on what paper you're talking about. The average sheet of 20lb copier paper is 0.0038 inches thick; whereas the average sheet of cardstock is 0.0175 inches thick. For a great resource of various thicknesses visit http://iconix.biz/info/paper-weights.htm

To measure the thickness of a thin piece of wire we have got the instrument called the wire gauge. The thickness of a thin piece of wire is measured in mm.

A thin sheet of paper is considered translucent, which means it allows some light to pass through but scatters it in the process. This is why you can see shapes and shadows through a piece of paper, but not clearly.

Extremely thin thicknesses are considered foil or leaf. The aluminum foil is a solid sheet of aluminum (or alloy rolled to a thickness of 0.0059inches or less). At a thickness of 0.006inches or more it is referred as sheet and thickness more than 6 mm (0.25 in) is considered as plate.
0.03mm is very thin, approximately equivalent to the thickness of a piece of paper.
It is a thin ,transparent sheet used to cover copies and books .
A paper sheet or a piece of thread can be used as a thin divider.
A sheet of gold can be hammered to be extremely thin, typically around 0.0001 millimeters in thickness. Gold is highly malleable and can be beaten into very thin sheets without breaking due to its softness.
