The flag is a vertical tricolour of blue, yellow, and red with the coat of arms of Andorra in the center. Although the three vertical bars may at first appear to be of equal width, the centre yellow bar is slightly wider than the other two so that the ratio of bar widths is 8:9:8. The overall flag ratio is 7:10. The design is related to the flags of France, Spain, Catalonia and Foix, the lands historically linked with the small country.
