Switzerland
Switzerland’s flag has a 1:1 ratio. To put it colloquially, the flag is square.
There are very few square national flags, and Switzerland’s flag is one of them. Vatican City’s is square too.
The white cross on red has older military roots. The Swiss federal authorities date the national emblem’s official adoption to 1848; the cross’s proportions were defined in 1889.
During the Helvetic Republic (1798–1803), a green, red and yellow tricolor replaced the cross design. It did not last beyond that regime.
Denmark
This flag also uses a red background, but its shape is rectangular.
The white cross reaches all four edges. Its upright arm is shifted toward the flagpole, unlike Switzerland’s centered, free-standing cross.
Known as Dannebrog, it is one of the world’s oldest national flags still in use. The story that it fell from the sky in 1219 is a legend; documented use dates to the 14th century.
