Need a ruler-friendly number? The size of a dollar bill is close to 6⅛ by 2⅝ inches. The bill covers about 16 square inches.
The bill isn’t really paper. It’s a blend of 75% cotton and 25% linen, according to Wikipedia’s one-dollar bill entry. That cotton-linen blend makes it hard to counterfeit. It also helps a bill survive a trip through the wash. Dollar Bill Dimensions Guide
Dollar Bill Size Ratio and Thickness
What is the dimension ratio of a US dollar bill? The length-to-width ratio is about 2.35 to 1. Divide 6.14 by 2.61 and you get 2.35. In plain terms, the bill is a bit more than twice as long as it is wide.
Thickness is tiny. A single note is 0.0043 inches thick. Stack 100 bills and you get a pile under half an inch tall (about 0.43 inches). Stack 1,000 and it reaches roughly 4.3 inches.
A dollar bill provides a handy reference for understanding everyday measurements, but familiar household items can make size comparisons even easier. For another practical example, explore the dimensions of a standard Pringles can to see its height, diameter, and measurements in inches and centimeters.
Weight adds up too. At about 1 gram each, around 454 bills make a pound.
Are All US Bills the Same Size? ($1 to $100)
Yes. Every US banknote is the same size, from the $1 to the $100. Each one measures 6.14 by 2.61 inches. Alliant Credit Union notes the same dimensions for the $1 bill.
How wide is a $20 bill in inches? A $20 bill is 2.61 inches wide, exactly like a $1 bill. Its length is 6.14 inches too.
Why does this matter? Machines. ATMs, vending machines and cash counters all expect one standard size. So the denomination shows in other ways: the portrait, the numeral, and the color on newer designs.
Two more facts help here:
- The $1 bill has stayed the same in design for decades. Bigger bills have been redesigned for anti-counterfeiting, but there are no current plans to redesign the $1 or $2.
- Bills last different lengths of time. The Federal Reserve puts the average $1 bill’s life at 6.6 years.
Dollar Bill Size: History, Comparisons & Uses
Old US money was bigger. Before 1928, “large-size notes” measured about 7.42 by 3.125 inches. People called them “horse blankets.” In 1928, the Treasury moved to the small-size note we use today, as the US dollar article on Wikipedia explains.
Here’s a fun detail. Today’s size matches the Philippine peso notes issued under US rule after 1903.
Want to picture the dollar bill length? Try these:
- It is about half a foot long.
