Flag of Switzerland late 13th or early 14th century. Its symbolism was described by the Swiss Federal Council in 1889 as representing "at the same the Christian cross symbol and the field sign of the Old Confederacy". As a national ensign, it was first used in 1800 during the Hundred Days by general Niklaus Franz von Bachmann, and as regimental flag of all cantonal troops from 1841. The federal coat of arms ("eidgenössisches Wappen") was defined in 1815 for the Restored Confederacy as the white-on-red Swiss cross in a heraldic shield. The current design was used together with a cross composed of five
Flag of Switzerland as the cross arms, so that the total height of the cross is fixed at 20:32 = 5:8 of the height of the flag (in other words, the width of the margin is 6:32 = 3:16). This ratio is also given as a "vexillological recommendation" in the flag regulation used by the Swiss Armed Forces. Flags with a cross of larger relative widths than the prescribed 20:32 = 62.5% remain in wide use; common ratios include 20:26 ≈ 76.9% and 20:28 ≈ 71.4%. For the ensign, the ratio of the size of the cross to the height is likewise 5:8,
