1. Exclusive Area

Area actually used for living (rooms, living room, kitchen, bathroom). Balconies are excluded as service areas.

2. Residential Common Area

Area shared by multiple households, such as hallways, stairs, and elevators.

3. Supply Area

Exclusive Area + Residential Common Area. This is the standard used for sales listings (e.g., "34 Pyeong Type").

📌 Area Ratio

The percentage of exclusive area relative to the supply area. Apartments are usually high (70-80%), but officetels are lower (40-50%) due to more common areas.

Using Area Conversion for Real Estate

One pyeong is about 3.3058 m². An apartment advertised as "34 pyeong" usually refers to supply area including shared space; living space is the exclusive area.

Worked example: How big is an 84 m² apartment?

Exclusive area: 84 × 0.3025 ≈ 25.4 pyeong
Supply area varies, typically 110–115 m²
At 112.5 m² supply: 112.5 × 0.3025 ≈ 34 pyeong, the familiar "34-pyeong type"

Hearing "34 pyeong" and expecting 34 pyeong of living space overstates the size. Compare exclusive areas.

Before you rely on the result

Check exclusive area before advertised pyeong.
Check whether the balcony has been expanded.
Compare maintenance fees and the shared-area ratio.
Before signing, verify the area in official records or listing documents.

Frequently asked questions
