Pyeong is a traditional Korean unit of area (about the size of two tatami mats) that remains common in everyday conversation about apartment sizes, even though official listings must state square meters by law.
The famously popular "national size" (국민평형) apartment is 84 m², commonly marketed as 33 or 34 pyeong depending on the area standard used. Smaller studio units often run 18–24 pyeong, while larger family units reach 40+ pyeong.
