Korean Area Units Explained: Pyeong, Square Meters, and Real Estate Measurements
Everything about the Pyeong unit — its history, conversion to square meters, common apartment sizes, and the difference between exclusive and supply area.
If you're looking at real estate in Korea, you'll encounter the term 'pyeong' (평) everywhere. Despite Korea officially adopting the metric system, pyeong remains the most commonly used unit for describing property sizes. Understanding pyeong and its relationship to square meters is essential for navigating the Korean property market.
What is a Pyeong?
Pyeong (평) is a traditional Korean-Japanese unit of area measurement. Originally derived from the Japanese 'tsubo' (坪), it was widely used during the Japanese colonial period and has persisted in everyday Korean usage. One pyeong equals approximately 3.30579 square meters (㎡), which is roughly the size of two tatami mats laid side by side.

Korean apartments are typically described by their supply area in pyeong. Here are the most common sizes:
- 18 pyeong (59㎡ exclusive): Studio or small 1-bedroom. Popular with singles and couples.
- 24 pyeong (79㎡ exclusive): 2-3 bedrooms. Suitable for small families. Often called '국민평수' (national standard).
- 32 pyeong (106㎡ exclusive): 3-4 bedrooms. Mid-size family apartment.
- 34 pyeong (112㎡ exclusive): Similar to 32 pyeong but with slightly more space.
- 40 pyeong (132㎡ exclusive): Large 4-bedroom. Premium family apartment.
- 50+ pyeong (165㎡+ exclusive): Luxury apartment or penthouse.
Exclusive Area vs. Supply Area
Understanding the difference between exclusive area (전용면적) and supply area (공급면적) is crucial:
- Exclusive Area (전용면적): The actual livable space inside your unit — rooms, living room, kitchen, bathrooms. This is what you can use.
- Supply Area (공급면적): Exclusive area + common areas (hallways, stairs, elevator halls) allocated to your unit.
- Contract Area (계약면적): Supply area + other common areas (parking, management office). The largest number.
- Exclusive ratio (전용률): Exclusive ÷ Supply, typically 70-85%. Higher is better for residents.
When comparing apartments, always compare the exclusive area (전용면적) for a fair assessment. A '34 pyeong' apartment in one complex may have different exclusive area than a '34 pyeong' in another complex.
Legal Status of Pyeong
In 2007, Korea passed a law requiring all official measurements to use metric units. Real estate listings must use square meters (㎡) as the official unit. However, in practice, most Koreans still think and communicate in pyeong. Real estate agents, advertisements, and everyday conversations predominantly use pyeong, with ㎡ shown in parentheses for legal compliance.
Frequently Asked Questions
Why is pyeong still used if it's not official?
Pyeong has been used in Korea for over a century and is deeply embedded in cultural understanding of space. People intuitively know that 30 pyeong is a decent family apartment, while 60 pyeong is spacious. This cultural familiarity makes it hard to replace, even with official metric requirements.
How do I calculate the actual living space from a listing?
Look for 전용면적 (exclusive area) in ㎡, then divide by 3.3058 to get pyeong. For example, '전용 84㎡' = about 25.4 pyeong of actual living space. The 공급면적 includes shared spaces and will always be larger.
What is a good exclusive ratio (전용률)?
A typical exclusive ratio is 75-80%. Above 80% is considered very good (more of your payment goes to actual living space). Tower-type apartments tend to have lower exclusive ratios (70-75%) due to larger common areas like elevator lobbies.
How do pyeong measurements differ for houses vs. apartments?
For houses, pyeong typically refers to the lot (land) size, not just the building footprint. A '50 pyeong house' usually means the land is 50 pyeong (165㎡), while the building itself may be smaller. For apartments, pyeong refers to the unit's supply area.
