The national flag of Switzerland (German: Schweizerfahne; French: drapeau de la Suisse; Italian: bandiera svizzera; Romansh: bandiera da la Svizra; Latin: Vexillum Helvetiae) displays a white cross in the center of a square red field. The white cross is known as the Swiss cross or the federal cross. Its arms are equilateral, and their ratio of length to width is 7:6. The size of the cross in relation to the field was set in 2017 as 5:8. Alongside the flag of Vatican City, the Swiss flag is one of only two square national flags in the world
