Why Is Switzerland's Flag Square Instead of Rectangular?

If you've ever seen the Swiss flag next to any other national flag, you've probably noticed that it's a bit different :  it's a perfect square. Almost every other country on Earth uses a rectangular flag (except Nepal, but it'll be the topic of another article), usually in a 2:3 or 3:5 ratio. Switzerland (and Vatican City) are exceptions.


So why the square?


The answer goes back to the Swiss military. The white cross on a red background was originally a battlefield symbol used by Swiss soldiers as early as the 14th century, worn on clothing and shields to identify friendly troops. When Switzerland officially adopted the design as its national flag in 1889, the square shape stuck — partly out of tradition, and partly because the cross itself is a symmetrical shape. Stretching it into a rectangle would have meant either distorting the cross or leaving awkward empty space on either side.

There's actually a second version of the flag too: a rectangular one, used at sea. Since international maritime law requires ships to fly rectangular flags for visibility and signaling purposes, Swiss vessels use a slightly elongated version of the same design. On land, though, the square remains standard.


This is actually one of the small details that makes building accurate flag assets more interesting than people expect. Most video and graphic tools are built around rectangular frames, so a perfectly square flag needs a bit of extra care to render properly without looking stretched or cropped. We ran into exactly that while building our World Pack — every flag was adjusted individually to keep the original proportions readable, even the ones (like Switzerland's) that don't have the usual ratio. Most times, we chose to keep the pattern and symbol untouched, and just resorted to have more empty space on top or on the sides. 


If you're working on a project that touches Swiss history, alpine culture, or international organizations (Switzerland hosts a lot of them), it's worth double-checking that whatever flag footage you're using respects the actual shape — a stretched Swiss cross is a small detail, but it's the kind of thing that your Swiss viewers (or flags amateur) will notice. Representation matters, so it's up to the people creating the visuals to do it properly !


This is why we choose to not use AI at any point in our flag designs, though it can look pretty nice from afar and create good looking pictures, accuracy matters the most when it comes to country symbols.
