The dimensions of the stars and stripes are specified by law:
"The proportions of the design are prescribed in terms of the hoist, or vertical height, of the flag as follows: the upper white portion shall be 3/10 of the hoist; the two horizontal bars are each 2/10 of the hoist; the white area between the bars 1/10 of the hoist; and the base, or lowest white space, is 2/10 of the hoist. The three five-pointed stars have a diameter of 2/10 of the hoist and are spaced equidistant in the fly, or horizontal, dimension of the flag."
Before 1938, the District of Columbia did not have an official flag, so, when needed, an unofficial banner was flown, usually theflag. In 1917, the National Geographic Magazine reported a flag supposedly used as unofficial flags of District of Columbia: the flag of District of Columbia Militia. It contained a hammer and the writing "HEADQUARTERS" and "DISTRICT OF COLUMBIA MILITIA". According to the same magazine, in 1937, the flag was replaced by one with the DC crest: the in front of a flaming sun, and same writing.
Only in 1938 an official flag was chosen, in a public competition. The winner entry, by Charles A.R. Dunn, is still the official D.C. flag. The first time Dunn proposed the flag was in 1921.
In July 2002, the D.C. Council approved a change in district flag, by 10-2 vote (and one absence), in protest in favor of DC statehood. The referred proposal included the "DC" writing in central star, and the text "TAXATION WITHOUT" in superior red bar and "REPRESENTATION" in inferior one. However, the bill never was signed by the then-mayor nor the successors.
