Switzerland’s national flag was adopted on December 12, 1889, which is one of the world’s oldest flags. The Flag of Switzerland is a red field, a white cross whose arms are one-sixth longer than their width. The relationship between the span of the cross and the width of the flag has not been established, but in practice the ratio is about 2:3 or 7:10.^[1]
