USA Currency Bills
This web page gives the basic information about U.S. currency and various bills in circulation. U.S. currency is produced at U.S. Treasury locations in Washington, D.C., and Fort Worth, Texas.

All bills are the same size, irrespective of denomination.
Dimensions: Width 2.61 inches x length 6.14 inches.
Thickness: 0.0043 inches.
Paper: 25 percent linen, 75 percent cotton.
Red and blue synthetic fibers of various lengths are distributed evenly throughout the paper.

Although all denominations are the same size and same green color, the amounts are clearly printed on the bills (currency notes are called bills in the U.S.). The designs are also similar. Pay careful attention when counting out paper money. It is easy to confuse the denominations and to make a mistake, giving a $10 bill, for example, when you intended to give $1.
