How to use the pyeong converter
Type a size in pyeong and the square-meter value appears instantly, along with square feet. The quick buttons cover the most common apartment sizes. The "estimated exclusive area" line shows roughly how much private living space you get when the pyeong figure is a supply-area size, which is how most apartments are described in conversation and in ads.
What is a pyeong?
The pyeong (평, sometimes spelled "pyung") is a traditional East Asian area unit equal to a square 6 ja (Korean feet) on each side. Japan's tsubo is the same size. Since July 2007, Korean law has required square meters in contracts, sales notices and advertising, but people still talk about homes in pyeong — "we live in a 34-pyeong apartment" is everyday Korean.
Pyeong to m² formula
One ja is 10/33 m, so 1 pyeong = (60/33)² m² = 400/121 m² ≈ 3.305785 m² (about 35.58 sq ft).
m² = pyeong × 400 ÷ 121 sq ft = m² × 10.7639
34 pyeong × 400 ÷ 121 = 112.40 m² ≈ 1,210 sq ft. The common shortcut "× 3.3" is about 0.2 m² low at 34 pyeong and the error grows with size, so use the exact value for contracts and taxes.
Why is a "34-pyeong" apartment only 84 m²?
When Koreans quote an apartment size in pyeong, they usually mean supply area, which includes a share of the stairwell and hallways. Korean listings break floor area down like this:
- Exclusive area (전용면적, jeonyong myeonjeok) — the space inside your front door that only you use. This is the official figure for registries, taxes, housing subscriptions and loans.
- Residential common area — stairs, corridors and elevator lobbies shared within the building.
- Supply area (공급면적, gonggeup myeonjeok) = exclusive + residential common area. The everyday "pyeong" size.
- Contract area = supply area + other common areas (management office, parking).
- Service area — mainly balconies, which are not counted but are often enclosed and used as living space.
A 34-pyeong apartment has a supply area of about 112 m², of which roughly 84 m² is exclusive. The ratio of exclusive to supply area (the efficiency ratio) is about 75–80% for stair-type apartment buildings, lower for corridor-type buildings, and often only 50–60% for officetels. Two apartments with the same pyeong label can therefore differ noticeably in real living space.
Comparing with US and other listings
The standard 84 m² (34-pyeong) Korean apartment has about 904 sq ft of exclusive living space, usually three bedrooms and two bathrooms, plus an enclosed balcony that often adds 25–30 m². When comparing with US listings in square feet, compare the exclusive area — the closest match to US "living area".
Mental math
pyeong × 3.3 is close enough for conversation. For square feet, pyeong × 35.6. 25 pyeong → 82.6 m² → about 890 sq ft.
Exclusive areas per size are typical examples and vary by complex and floor plan. For exact figures, check the sales notice, building register or real-estate registry.
