How many square meters is 1 pyeong?

1 pyeong = 3.305785 m² (exactly 400/121 m²), and conversely 1 m² = 0.3025 pyeong. Pyeong comes from the area of a square with 6-ja (about 1.818 m) sides. The legal unit is m², but pyeong is still widely used in Korean real estate.

How many pyeong is 84 square meters?

84 m² is about 25.41 pyeong (84 ÷ 3.305785). Note that the famous "national size" 84 m² exclusive-area apartment usually has a gross area of 108-114 m², so it is marketed as a "33-34 pyeong type". Always check which area basis is used.

What is the difference between exclusive and gross area?

Exclusive area is the private space inside your door (rooms, living room, kitchen, bath). Gross (supply) area adds shared residential space such as stairs, corridors, and elevator halls. Contracts use exclusive area, while the colloquial "n-pyeong type" uses gross area.

Exclusive vs. Gross Area — What Is the Difference?

Exclusive area: the space inside your front door (rooms, living room, kitchen, bath). This is the legal area on the registry and sales contract. Balconies (bonus area) are not included.
Gross (supply) area: exclusive area + shared residential area (stairs, corridors, elevator halls). The colloquial "n-pyeong type" refers to gross area. Example: a 112 m² (≈34-pyeong type) apartment usually has an exclusive area of 84 m².
The same "84 m²" feels very different depending on whether it is exclusive or gross area — always check which one a listing uses.

Everything About Pyeong Conversion

Korean real estate listings and registries use square meters, while everyday conversation still runs on pyeong. One pyeong equals 3.305785 m² (400/121 m²), derived from a square with 6-ja (about 1.818 m) sides. This converter switches between pyeong and m² instantly in both directions and provides a table of common apartment sizes.

Quick mental math: multiply m² by 0.3 for an approximate pyeong value (84 m² × 0.3 ≈ 25 pyeong). The exact conversion is m² ÷ 3.305785: 84 m² = 25.41 pyeong, 59 m² = 17.85 pyeong, 101 m² = 30.55 pyeong. Conversely, multiply pyeong by 3.3 to approximate m² (25 pyeong ≈ 82.6 m²).

The area basis matters. A "34-pyeong type" in a sales ad refers to gross (supply) area — exclusive plus shared residential area — while the registry lists exclusive area. An 84 m² exclusive-area apartment typically has around 110 m² of gross area, so the same home is called both "25 pyeong" and a "34-pyeong type". Extended balconies (bonus area) make the usable space feel even larger.
