How thick is a dollar bill?
A dollar bill is 0.0043 inch (0.109 mm) thick, the same as every US note, according to the Bureau of Engraving and Printing.
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.

| 10 | $10 | 0.043 in (1.1 mm) | 10 g (0.35 oz, 0.022 lb) |
| 100 | $100 | 0.43 in (10.9 mm) | 100 g (3.53 oz, 0.22 lb) |
| 500 | $500 | 2.15 in (54.6 mm) | 500 g (17.64 oz, 1.102 lb) |
| 1,000 | $1,000 | 4.3 in (109 mm) | 1,000 g (35.27 oz, 2.205 lb) |

The Bureau of Engraving and Printing FAQ says current notes measure 2.61 inches wide by 6.14 inches long, and the thickness is 0.0043 inch. That is 0.109 mm, so about 233 notes make an inch of stack. The same thickness applies to every denomination, from $1 to $100.
Stack height is the number of notes times 0.0043 inch. 100 $1 bills ($100) are 0.43 in (10.9 mm) tall; 10,000 bills ($10,000) are 43 in (3.58 ft, 1.09 m). Real stacks can be taller because paper curls and traps air, and the figure comes from an archived 2004 version of the Bureau FAQ, so treat it as a close estimate, not a measurement of the bill in your hand.
