Page "Flag of the United States" Paragraph 21

These specifications are contained in an executive order which, strictly speaking, governs only flags made for or by the U. S. federal government.

In practice, most U. S. national flags available for sale to the public have a different length-to-width ratio ; common sizes are or ( flag ratio 1. 5 ), or ( 1. 6 ), or or ( 1. 667 ).

Even flags flown over the U. S. Capitol for sale to the public through Representatives or Senators are provided in these sizes.

Flags that are made to the prescribed 1. 9 ratio are often referred to as " G-spec " ( for " government specification ") flags.
