Image notes

  • The geometric specifications for the union jack and the sizes and positioning of the stars are given in an attachment to Executive Order 10834 of 21 August 1959, printed in 3 CFR, 1959–1963 Comp., p. 368.
  • The current dimensions of the image (version of 00:43, 14 May 2008), 1235 × 650 pixels (which represents an aspect ratio of 1.9:1.0), were chosen to allow as much as possible of the final geometric manipulations to be performed using whole numbers, avoiding the need for scaling. (This also results in each stripe being 50 pixels high.)
  • The versions of 04:42, 5 April 2007, and later (which were written from scratch) are ineligible for copyright and in the public domain. (Earlier versions were derived from the Open Clip Art library and were covered by the Open Clip Art license.)
  • The current version of this image (version of 00:43, 14 May 2008) has been checked to be valid SVG 1.1.
It is easy to put a border around this image:
