What is the measurement of paper money now?

The standard size of paper money varies by country, but in the United States, for example, the dimensions of a dollar bill are 6.14 inches (156 mm) in length and 2.61 inches (66.3 mm) in height. Most countries have adopted similar dimensions for their banknotes, often around 6 to 7 inches long and 2 to 3 inches wide. Additionally, many nations are experimenting with different sizes and orientations to enhance security and usability.
