How it is described

The flag in the words of vexillology and heraldry.

Vexillological description

It is a rectangular field with a 28:37 ratio, red, with a white cross shifted towards the flagpole (the type called a Nordic cross).

Cross
its two arms measure 12 units wide on a height of 28: it leaves, on each side, red stripes of 7 units both vertically and horizontally.
Ratio
the 28:37 measure is recommended by the army since 1893, though the law does not require it.
Field
no other figures: it is the Dannebrog, “the flag of the Danes”.

The full story

How it was born, how it has changed and what it means.

The flag of Denmark is red with a white cross. The Danes call it the Dannebrog, which means “cloth of the Danes” or “red cloth”. It is the oldest national flag still in use today and the model from which all the other Nordic flags came.

How it came about

Nobody knows exactly when it began to be used. The oldest evidence is a fourteenth-century Dutch book of coats of arms, the Armorial Gelre, which draws a red standard with a white cross next to the arms of the king of Denmark.

Tradition tells another story. On 15 June 1219, in a battle in Estonia, the troops of King Valdemar II were losing when the flag fell from the sky and gave them victory. It is a legend: nobody wrote it down until the sixteenth century, nearly three hundred years later. Historians think the cross comes from the Christian standards carried by the crusaders of that time.

How it has changed

The colours have been the same since the Middle Ages; what has changed is the position of the cross.

    14th century

    At first the cross is in the centre, as in many medieval standards.

  2. 1748

    Over time the vertical arm has moved closer to the mast and the horizontal one has lengthened towards the other side: it is the Nordic cross. A rule fixes the thickness of the cross and the size of each red rectangle.

  3. Current flag of Denmark

    1893

    A slightly longer version is allowed, the one with a 28:37 ratio, which is now the most usual.

What it means

No law gives it a meaning, but its elements are understood as follows:

  • White cross

    Christianity, as on the standards of the medieval kings and crusaders.

  • Red

    the ground of the old war standard of the Danish kings.

  • Cross shifted towards the mast

    the drawing that Sweden, Norway, Finland, Iceland and the Faroe Islands later copied.

Fun facts

  1. A world record

    The Guinness Book of Books recognises it as the national flag used without interruption for the longest time, at least since 1625.

  2. From forbidden to omnipresent

    In 1834 private citizens were forbidden to fly it: it was a thing of the army. In 1854 the ban was lifted. Today the Danes put it on birthday cakes and, since the mid-nineteenth century, also on the Christmas tree.

  3. Only the Danish one

    From 1915, flying the flag of another country on Danish soil was forbidden, with a few exceptions. The rule was lifted in 2023, after a ruling of the Supreme Court.

  4. Two reds

    The Danish Navy uses a darker red than the flag flown on land.
