Updated 17 April 2026
100 m² is approximately about the size of a singles tennis court (195 m2 total, you have half the court).
1 m² = 10.7639 ft²
To convert m² to ft², multiply by 10.7639. To convert ft² to m², divide by 10.7639 (or multiply by 0.0929).
Property Size Reference
Most people converting square metres to square feet are looking at international property listings. Here is what the numbers look like in practice. See also apartment sizes by city and UK home sizes.
Studio flat (compact)
One room as bedroom, living room, and kitchen. Standard in Tokyo, Hong Kong, London.
1-bed apartment (urban)
Separate bedroom, open kitchen-living. Common in Paris, Barcelona, Melbourne.
2-bed apartment
Two bedrooms, living room, kitchen, bathroom. Typical European city flat.
3-bed house (suburban)
Three bedrooms, living, dining, kitchen, one to two baths. Average UK home.
4-bed detached house
Four bedrooms, multiple living areas. Standard US suburban home.
Large family home
Five or more bedrooms, multiple reception rooms.
Mansion or estate
Extensive grounds. Multiple dwellings typically not included in the m2 figure.
International Real Estate Conventions
Most of the world measures property in square metres. When American or British buyers look at listings in Europe or Asia, they encounter m2 and need to convert. But there is a subtlety: not all m2 figures mean the same thing.
Spain
Listings show "superficie util" (usable area) and "superficie construida" (constructed area, includes walls). Constructed area is typically 15-20% larger. Always check which one is quoted.
France
The "Loi Carrez" area is the legal measurement for apartment sales. It excludes areas with ceiling height below 1.80 m, cellars, garages, and outdoor spaces. A listed "45 m2 Loi Carrez" apartment might have a total footprint of 55-60 m2.
Thailand
Condos are listed in square metres. Houses and land may use "talang wah" (4 m2 per talang wah) or "rai" (1,600 m2 per rai).
Japan
Property is measured in "tsubo" (approximately 3.31 m2 or 35.58 ft2). A "20 tsubo" apartment is about 66 m2 or 710 ft2.
Australia
Uses square metres. "Internal area" excludes balconies, garages, and storage. Sydney apartments average 65-80 m2 internal for a two-bed.
United Kingdom
Historically used square feet but transitioning to square metres. Expect to see both. Estate agents are inconsistent; always verify which unit is used.
Germany
"Wohnflache" is living space in m2. Balconies typically counted at 25-50% of their area by convention.
How to Convert Square Metres to Square Feet
The Formula
Multiply square metres by 10.7639 to get square feet:
Example: 85 m2 in Barcelona
85 × 10.7639 = 914.93 ft²
A comfortable two-bedroom apartment by European standards.
Reverse: 500 ft2 to m2
500 / 10.7639 = 46.45 m²
A typical New York studio apartment.
Mental Shortcut
Multiply by 11 and subtract 2-3%. So 50 m2 is roughly 50 × 11 = 550, minus about 12, giving approximately 538 ft2. The exact answer is 538.20 ft2, so this shortcut is close enough for house-hunting. For a fast overestimate, just multiply by 11.
Where Does 10.7639 Come From?
One metre is defined as exactly 3.28084 feet (per the 1959 international yard and pound agreement). Since area is two-dimensional, you square the linear factor: 3.28084 × 3.28084 = 10.76391041671. Rounded to 10.7639, this is the accepted conversion factor used in all engineering, real estate, and scientific applications. See the full formula derivation for more detail.
