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 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, "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 or Wolse 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).
Real Estate Measurement FAQ
How much is 1 Pyeong in Square Meters?
Exactly 1 Pyeong is 3.305785 Square Meters (㎡). For quick mental math, Koreans often multiply by 3.3.
Why do apartments feel smaller than the listed size?
This is because realtors usually quote the "Supply Area" (공급면적), which includes common hallways and elevators. Your actual living space (Exclusive Area) is typically 70-80% of that number.
What is the standard size for a 3-bedroom apartment?
The most common family apartment size in Korea is the "84㎡ Exclusive Area" (National Standard Size), which is roughly equivalent to a 25 Pyeong exclusive area (or 32-34 Pyeong supply area).
