North Korea has changed the proportions of its national flag for the first time since the country’s establishment in 1948, breaking with a decades-old design closely associated with founding leader Kim Il Sung.

The DPRK government’s official website Naenara recently began displaying a flag with the aspect ratio 1:1.65, replacing the previous banner using the 1:2 ratio.

The two thin white stripes in the flag also appear thicker than before, widened to roughly a third of the blue stripes at the top and bottom.
