    I’m building a 2-1/2’x 4’ flag, what are the dimensions for the stars, stripes and union? Thanks

    I got this from the web...

    The basic design of the current flag is specified by 4 U.S.C. § 1; 4 U.S.C. § 2 outlines the addition of new stars to represent new states. The specification gives the following values:

    Hoist (height) of the flag: A = 1.0
    Fly (width) of the flag: B = 1.9[64]
    Hoist (height) of the canton ("union"): C = 0.5385 (A × 7/13, spanning seven stripes)
    Fly (width) of the canton: D = 0.76 (B × 2/5, two-fifths of the flag width)
    E = F = 0.0538 (C/10, One-tenth of the height of the canton)
    G = H = 0.0633 (D/12, One twelfth of the width of the canton)
    Diameter of star: K = 0.0616 (L × 4/5, four-fifths of the stripe width, the calculation only gives 0.0616 if L is first rounded to 0.077)
    Width of stripe: L = 0.0769 (A/13, One thirteenth of the flag height)

    These specifications are contained in an executive order which, strictly speaking, governs only flags made for or by the U.S. federal government.[65] In practice, most U.S. national flags available for sale to the public have a different width-to-height ratio; common sizes are 2 × 3 ft. or 4 × 6 ft. (flag ratio 1.5), 2.5 × 4 ft. or 5 × 8 ft. (1.6), or 3 × 5 ft. or 6 × 10 ft. (1.667). Even flags flown over the U.S. Capitol for sale to the public through Representatives or Senators are provided in these sizes.[66] Flags that are made to the prescribed 1.9 ratio are often referred to as "G-spec" (for "government specification") flags.
