Flag of Switzerland is composed of five squares. The absolute width of the flag is given as 4.5 feet (105 cm), that of the cross as 3 feet (90 cm), for a ratio of cross to flag width of 2:3 ≈ 66.7% (as opposed to the modern 5:8 = 62.5%). The specifications include the flag pole and the ribbon with the cantonal colours attached to the pole (the example depicted is the flag of the Zürich battalion). The flag itself is described as of good silk cloth, four feet five inches squared, scarlet, in the center a white cross, arms measuring one foot
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,
