How to Calculate the Size of the United States Flag

The size and proportions of the American flag and the elements on it such as the Union, stars, and stripes are governed by executive order 10834 dated August 21, 1959.^[1] Signed by Dwight David Eisenhower, the executive order sets the standard dimensions, standard proportions, and positions for the flag elements.

While this order defines standards for the size of the flag used by government agencies, the size of flags for personal use may vary. A 3′ × 5′ flag is the most common size for personal use.

When designing a custom-made flag, no word, figure, mark, picture, design, drawing, or any advertisement of any nature may be placed on any flag, standard, colors or ensign of the United States of America. For more information on properly displaying and handling your custom-made American flag, check out U.S. Code Title 4 Chapter 1 – the Flag.^[2]

To find the size of the flag or a part of the flag, multiply the proportion for the element from the table below by the desired width, or hoist, of the flag.
