Korean apartment size from private area
How to convert m² to pyeong
- Type a number into whichever unit you know — m², pyeong or sq ft. The other two fill in instantly.
- To see how a Korean listing’s “N-pyeong” size relates to the actual private area, use the second box.
The formulas: pyeong = m² × 0.3025, m² = pyeong × 3.3058, sq ft = m² × 10.7639.
Common Korean apartment sizes
| Private area | Pyeong | Sq ft | Listed as |
|---|---|---|---|
| 39 m² | 11.8 | 420 | 16–17 pyeong |
| 59 m² | 17.8 | 635 | 24–25 pyeong |
| 74 m² | 22.4 | 797 | 29–30 pyeong |
| 84 m² | 25.4 | 904 | 33–34 pyeong |
| 114 m² | 34.5 | 1,227 | 45–46 pyeong |
“Listed as” sizes use supply area (private + shared hallways and stairs) and vary by complex.
Good to know when reading Korean listings
- Contracts use private area. Compare prices per private m², not per listed pyeong.
- Officetels have lower ratios (50–60%). A “20-pyeong” officetel can be much smaller inside than a 20-pyeong apartment.
- Balcony extensions aren’t counted. Extended units feel bigger than the paperwork says.
