What's with the funny shape of Nepal's flag?

The World

When you look at a chart of the world's national flags, Nepal's jumps out at you. It's the world's only non-quadrilateral national flag. 

A quadrilateral is a four-sided polygon with two parallel side. Article 5 of Nepal's constitution states: "The national flag of Nepal, as handed down by tradition, consists of two juxtaposed triangular figures with a crimson-coloured base and deep blue borders, there being a white emblem of the crescent moon with eight rays visible out of sixteen in the upper part and a white emblem of a twelve-rayed sun in the lower part." Schedule 1 of the constitution provides exhaustive instructions on how to draw the flag. Here's just one of five steps needed to draw the border.  

"From A draw a line AC perpendicular to AB making AC equal to AB plus one third AB. From AC mark off D making line AD equal to line AB. Join BD."

"You really have to brush up on your geometry in order to be able to draw it from the description," says Graham Bartram, the chief vexillologist of The Flag Institute, a British non-profit devoted to the scientific and scholarly study of flags. Vexillology, by the way, is the "scientific study of the history, symbolism and usage of flags". 

Bartram describes the shape of Nepal's flag as two pennants on top of each other and says the pennant triangle is a traditional shape for flags in South Asia.  If so, then why is Nepal the only country in the entire world with the pennant shape for its national flag? 

"It's more a case of the rest of the world copied Europe and Nepal decided not to," says Bartram, who is British. "Europe chose rectangular flags because that's what we came up with and we came up with national flags before the rest of the world had them. And they all sort of said, 'Oh, in order to be a national flag you have to be rectangular' and Nepal said, 'No actually we're quite happy with our traditionally shaped flags.' Hindu flags are triangular. So is the Sikh khanda flag. Triangular flags are very culturally normal in that part of the world."

This Sikh flag, called the Nishan Sahib, is a another triangular flag from South Asia. It's made of cotton or silk cloth, with a tassel at its end. The word Nishan means symbol, and the flag is hoisted on a tall flagpole, outside most Gurdwaras, the place

The colors and symbols of Nepal's national flag have specific meanings. The flag is red with a blue border. "The flag is basically red, with a blue border. Red is Nepal's national color and it's said to come from the Rhododendron plant, which grows in the Himalayas. And blue is meant to represent peace. And on the top pennant you have the moon. And on the bottom pennant you have the sun." 

But what about the points of those two triangles off to the right? Could they be some sideways nod to the peaks of the Himalayas? Bartram says that's one explanation. "There are many theories as to why there are two of them and what they represent and one is that they represent the Himalayas. But there are many ideas as to why there are two of them."

One is that they represent Hinduism and Buddhism. Another is that they represent two families: the Shahs and the Ranas, who used to rule Nepal. Still another is that the two points represent peace with the moon and work with the sun. The official government interpretation is that they represent Hinduism and Buddhism. 

In the United States, there's a very specific way to fold the American flag. In Nepal, it's not clear — but flag expert Graham Bartram thinks there's a good chance they do like the British do and just roll it up into a tube.
