Why Does Korea Still Use "Pyeong" (평)?
As an expat or digital nomad looking to rent an apartment in Seoul, you will immediately notice that real estate listings (like on Zigbang or Naver Real Estate) often list the size in Pyeong (평 / Py) alongside Square Meters (㎡).
Despite the Korean government banning the official commercial use of traditional measurements in 2007 to comply with the metric system, "Pyeong" remains deeply ingrained in Korean culture. It represents roughly the space a person needs to lie down and stretch out their arms and legs.
The Magic Number: 3.3058
To manually convert, remember this golden rule: 1 Pyeong roughly equals 3.3058 Square Meters (or 35.58 Square Feet).
The Expat Trap: Supply Area vs. Exclusive Area
This is the #1 mistake foreigners make when signing a Jeonse (Key money) or Wolse (Monthly rent) contract. Korean listings define apartment sizes in two ways:
- Exclusive Area (전용면적): The actual living space inside your front door (bedroom, living room, bathroom). This is the number you care about.
- Supply Area (공급면적): The exclusive area PLUS your share of shared building spaces (hallways, staircases, elevators).
A listing might advertise "10 Pyeong", but that's usually the Supply Area. Your actual living space (Exclusive Area) might only be 6 or 7 Pyeong! Always ask the real estate agent (Budongsan) for the "Jeonyong Myeonjeok" (Exclusive Area).
