What does the Sweden flag look like?
The flag has a light middle-blue field with a gold-yellow cross shifted toward the hoist. Swedish law specifies that the cross must be perpendicular to the flag edges.
The standard rectangular flag has a height-to-length proportion of 10:16. Its geometry can be expressed as 4:2:4 vertically and 5:2:9 horizontally.
Why does Sweden use a Nordic cross?
Sweden’s National Archives says the design model was almost certainly borrowed from Denmark’s older Dannebrog. The off-center cross became a characteristic Scandinavian flag pattern adopted in different colors across the Nordic region.
Where do the blue and yellow colors come from?
The National Archives connects the colors to Sweden’s coat of arms: golden crowns on a blue field and gold heraldic elements dividing the greater arms.
The current official color guidance gives blue as NCS 4055-R95B / Pantone 301 and yellow as NCS 0580-Y10R, with Pantone references varying by coated or uncoated material.
How old is the Swedish flag?
The history of the Swedish cross flag reaches back to the mid-sixteenth century. The basic blue-and-yellow Nordic-cross form became established over time as a national and royal symbol.
Today its appearance is governed by the 1982 Swedish Flag Act, while a separate regulation defines official color shades.
Why are some Swedish flags swallow-tailed?
Swedish law recognizes both the ordinary rectangular flag and a three-tailed version. The three-tailed flag is used by the armed forces and can also be used by the monarch and, with permission, other members of the Royal House.
Why is June 6 important?
Swedish Flag Day has been celebrated nationally on June 6 since 1916. The date also became Sweden’s National Day in 1983.
