Dollar bill dimensions
A US dollar bill is 6.14 × 2.61 in (155.96 × 66.29 mm). Every current Federal Reserve note, from $1 to $100, is the same size.
Thickness (0.0043 in) is from the Bureau of Engraving and Printing FAQ as archived on 2004-10-15 by the U.S. government web archive. A loose stack of real notes can be taller than the figure here because of curl and air.

Federal Reserve notes were standardised in 1929, when the government made them about 30 percent smaller: 6.14 x 2.61 inches instead of 7.375 x 3.125 inches (uscurrency.gov). That works out to 155.96 mm by 66.29 mm.
The Bureau of Engraving and Printing gives the weight of a note as about one gram whatever the denomination, and says it takes about 4,000 double folds (forward and then backwards) before a note will tear. The denominations printed today are $1, $2, $5, $10, $20, $50 and $100. The thickness of a note is 0.0043 inch (0.109 mm) in the Bureau FAQ as archived in 2004.
