Flag of the City of London Flag of the City of London The flag of the City of London is based on the flag of England, having a centred red St George's Cross on a white background, with the red sword in the upper hoist canton (the top left quarter). The sword is believed to represent the sword that beheaded Saint Paul who is the patron saint of the city. The tip of the sword always points upwards; therefore, when the flag is held on its side as a banner, the sword would be printed to face hoist and would be located on the left as
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,
