The Flag of Sweden harkens back to the 16th century, and is believed to be modelled on the Danish flag, the Dannebrog. The colours of the flag are the same as the ones on the seal of the three crowns, the lesser state arms[?].
- According to Swedish law 1982:269, the dimensions of the flag are 10/16 (height/width), the inner blue fields having 4/5 and the outer blue fields 4/9 (height/width).
- According to Swedish law 1983:826, the colours used are established through the NCS color system to be: Yellow - NCS 0580-Y10R, blue - NCS 4055-R95B.
When used from a flagpole, the size of the flag is recommended to have a width equalling a fourth of the height of the pole.
