How the pyeong converter works
The pyeong (평) is the traditional Korean unit of floor area, and it is still the number people use when they talk about the size of an apartment in Korea. Listings, agents and neighbors say “34 pyeong” or “25 pyeong”, while contracts and registries are written in square meters. If you are renting, buying or just browsing from the United States, you probably think in square feet as well. This converter switches between all three units in any direction. If you also know the exclusive-area ratio, it shows the exclusive, supply and contract area of a Korean apartment side by side.
Convert in three steps
- Enter the area and pick its unit. Type the number from the listing and choose m², pyeong or sq ft. Korean listings usually show the area in square meters with a pyeong figure beside it, so you can enter whichever one you have.
- Say which area it is. Choose exclusive, supply or contract. If your contract or the property registry shows an exclusive-area ratio (the share of the supply area that is exclusive), type it in to unlock the full breakdown. A balcony extension area is optional.
- Read the result. The result updates as you type. You get the same area in all three units, plus exclusive, supply and contract area when a ratio is entered, and a usable-area figure with the balcony if you added one.

The conversion formulas
This tool uses 3.305785 square meters for one pyeong, which is the area of a square about 1.82 m (roughly 6 ft) on each side. A square meter is 10.7639104167 square feet, because one foot is defined as exactly 0.3048 meters. Everything else follows from those two numbers.
m² = pyeong × 3.305785 | pyeong = m² ÷ 3.305785
sq ft = m² × 10.7639104167 | m² = sq ft ÷ 10.7639104167
1 pyeong = 35.583 sq ft | 1 sq ft = 0.0281 pyeong
- 84.9 m² to pyeong and sq ft: 84.9 ÷ 3.305785 = 25.68 pyeong, and 84.9 × 10.7639104167 = 913.86 sq ft.
- 34 pyeong to m² and sq ft: 34 × 3.305785 = 112.40 m², and 112.40 × 10.7639104167 is about 1,209.8 sq ft.
- 1,000 sq ft to pyeong: 1,000 ÷ 10.7639104167 = 92.90 m², and 92.90 ÷ 3.305785 = 28.10 pyeong.
You will often see 3.3 used as a shortcut for one pyeong. It is fine for a rough idea, but the gap grows with size: 100 pyeong is 330.58 m², not 330, and 300 pyeong is 991.74 m², not 990. The converter always uses 3.305785.
| Pyeong | m² | sq ft |
|---|---|---|
| 1 | 3.31 | 35.6 |
| 10 | 33.06 | 355.8 |
| 20 | 66.12 | 711.7 |
| 25 | 82.64 | 889.6 |
| 30 | 99.17 | 1,067.5 |
| 34 | 112.40 | 1,209.8 |
| 40 | 132.23 | 1,423.3 |
| 50 | 165.29 | 1,779.2 |
Exclusive, supply and contract area
A Korean apartment can be described by three different areas, and listings do not always say which one they mean. They always grow in the same order: exclusive area is smaller than supply area, which is smaller than contract area.
- Exclusive area (전용면적): the space inside your front door that only your household uses, meaning the rooms, living room, kitchen and bathrooms. This is the figure that best matches how much living space you actually have.
- Supply area (공급면적): the exclusive area plus the shared residential space of the building, such as stairwells and corridors.
- Contract area (계약면적): the supply area plus other shared space, such as underground parking and the management office.
The exclusive-area ratio (전용률) is the exclusive area divided by the supply area. The higher the ratio, the more of the size you are quoted is space you actually live in. Because the amount of other shared space differs from building to building, this converter shows the contract line as a reference value equal to the supply area.
Why a “34 pyeong” apartment is about 25 pyeong inside
Names such as “25 pyeong type” or “34 pyeong type” come from older sales practice, when apartments were named by a rounded supply area. They are labels, not measurements of the space inside. The classic example is the apartment with an exclusive area of 84.9 m², which Koreans call the “national size” (국민평형). Converted directly, 84.9 m² is 25.68 pyeong, yet it is sold as a 34 pyeong apartment. If the exclusive-area ratio is 75 percent, the supply area is 84.9 ÷ 0.75 = 113.2 m², which is 34.24 pyeong, and that is where the 34 comes from.
The table uses the same 75 percent ratio as an assumption. Real ratios differ from complex to complex, so always check the figures in your own contract or registry record.
| Listed as | Exclusive m² | Exclusive pyeong | Exclusive sq ft | Supply pyeong | Supply sq ft |
|---|---|---|---|---|---|
| 25 pyeong type | 59.9 | 18.1 | 644.8 | 24.2 | 859.7 |
| 30 pyeong type | 74.5 | 22.5 | 801.9 | 30.0 | 1,069.2 |
| 34 pyeong type | 84.9 | 25.7 | 913.9 | 34.2 | 1,218.5 |
| 46 pyeong type | 114.7 | 34.7 | 1,234.6 | 46.3 | 1,646.2 |
Balcony extension and usable area
A balcony is a service area. It is not part of the exclusive area and not part of the supply area. Many Korean apartments have the balcony extended into the living space, which adds floor space you can use without changing the registered exclusive area. This tool adds the extension area you enter to the exclusive area and shows the total as the usable area with the balcony. For example, 84.9 m² plus a 10 m² extension is 94.9 m², which is 28.71 pyeong or 1,021.50 sq ft. New apartments are often sold with the extension as a standard option, so check the sales brochure before you assume it is included.
Mistakes to avoid
- Using 3.3 for every conversion. It looks harmless on a small unit, but it adds up on large floor areas. Use 3.305785 when the number matters.
- Comparing an apartment and an officetel by pyeong alone. Apartments are usually described by supply area, while officetels (buildings that mix office and residential use) are often described by contract area. A “30 pyeong” officetel can have a much smaller exclusive area than a “30 pyeong” apartment.
- Counting the balcony as exclusive area. Extending a balcony does not change the exclusive area in the registry. Enter it separately to see the usable area.
- Comparing Korean exclusive area directly with US listing square footage. Square feet in US listings may be measured by different rules than Korean exclusive area, so treat the conversion as a good estimate, not an exact match.
Getting a feel for the size
Square feet help if you are used to American apartments, but only as a rough guide. An exclusive area of 59.9 m² is about 645 sq ft, in the range of a typical one-bedroom apartment in many US cities. An exclusive area of 84.9 m², about 914 sq ft, is closer to a roomy two-bedroom. Sizes vary a lot by city and building, so treat these comparisons as approximate. The “size at a glance” panel under your result also shows the side of a square with the same area in meters and feet, and how many parking spaces, beds and table tennis tables would fit. At 84.9 m² that is about 6.8 parking spaces of 12.5 m² each.
Where to check the official numbers
In Korea, official documents state area in square meters. The pyeong lives on in everyday speech and in listing headlines. When you compare homes, sign a lease or file paperwork, use the m² figures in your contract and in the property registry, and treat the pyeong number as a convenient nickname. This converter is a calculation aid, so for any purchase or lease decision rely on the areas written in your documents.
Frequently asked questions
How many square feet are in a pyeong?
One pyeong is 3.305785 square meters, which is about 35.583 square feet. To convert pyeong to square feet, multiply by 35.583. For example, 25 pyeong is about 889.6 sq ft and 34 pyeong is about 1,209.8 sq ft.
How do I convert square feet to pyeong?
Divide the square feet by 35.583, or convert in two steps: divide by 10.7639104167 to get square meters, then divide by 3.305785 to get pyeong. A 1,000 sq ft apartment is 92.90 m², or 28.10 pyeong.
How big is a 34 pyeong apartment in square feet?
It depends on which area the 34 refers to. In Korean listings the number usually reflects the supply area. An apartment with an exclusive area of 84.9 m² (25.68 pyeong, 913.86 sq ft) is commonly sold as a 34 pyeong apartment. With an assumed 75 percent exclusive-area ratio, its supply area is about 113.2 m², or about 1,218 sq ft.
What is the difference between exclusive, supply and contract area?
Exclusive area is the space you use alone inside the front door. Supply area adds shared residential space such as stairwells and corridors. Contract area adds other shared space such as parking and the management office. Exclusive is always the smallest and contract the largest.
Why does the converter ask for an exclusive-area ratio?
The ratio, the exclusive area divided by the supply area, lets the tool work out the other areas from the one you know. You can leave it blank if you only want a plain conversion between m², pyeong and sq ft. The ratio is shown in your sales contract or the property registry record.
Does a balcony count toward the exclusive area?
No. A balcony is a service area outside both the exclusive and supply area. If it has been extended into the living space, enter the extension area to see the usable area with the balcony. The exclusive area in the registry does not change.
