Flag of Latvia the end of the occasion. If the flag is flown from a flagpole in mourning, it shall be raised to half-staff. If fixed to a flagstaff, a black ribbon whose width is the width of the flag shall be secured to the flagstaff above the flag; the ribbon shall be of sufficient length to span the width of the flag. The Standard of the President is white with the rectangular cross in the colour proportions of the national flag. In the centre of the cross covering the interruption of the colours of the national flag there is the Coat of
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,
