International Real Estate Conventions
Most of the world measures property in square metres. The United States measures in square feet. When American, Canadian, or British buyers look at property listings in Europe, Asia, South America, or Australia, they encounter square metre measurements and struggle to visualise the space. Here is what to watch out for in each country.
Spain
Listings show "superficie util" (usable area) and "superficie construida" (constructed area, includes walls). The constructed area is typically 15-20% larger. Always check which one the listing quotes.
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 / 710 ft².
Australia
Uses square metres. "Internal area" excludes balconies, garages, and storage. "Total area" includes them. Sydney apartments average 65-80 m² internal for a 2-bed.
United Kingdom
Historically used square feet in property listings but is transitioning to square metres. Expect to see both. Estate agents are inconsistent, so always verify which unit is used.
Germany
"Wohnfläche" is living space in m². Includes rooms, kitchen, bathroom. May or may not include balconies (usually counted at 25-50% of their area by convention).
How to Convert Square Metres to Square Feet
The Formula
Multiply the number of square metres by 10.7639:
Example 1: A 85 m² apartment in Barcelona
85 x 10.7639 = 914.93 square feet
That is a comfortable 2-bedroom apartment by European standards.
Example 2: Converting the other way (500 ft² to m²)
500 / 10.7639 = 46.45 square metres
A typical New York studio apartment.
Where does 10.7639 come from?
One metre is defined as exactly 3.28084 feet. Since area is two-dimensional, you square the linear conversion factor: 3.28084 x 3.28084 = 10.7639 (rounded to four decimal places). The full value is 10.76391041671... but 10.7639 is more than precise enough for any practical application, from real estate listings to architectural plans.
Quick mental shortcut
For a fast estimate in your head, multiply by 11 and subtract 2-3%. So 50 m² is roughly 50 x 11 = 550, minus about 12, giving you approximately 538 ft². The exact answer is 538.20 ft², so this shortcut gets you very close.
How to measure a room in square metres
Use a tape measure or laser distance tool to measure the length and width of the room in metres. Multiply length by width. For example, a room that is 4.5 m long and 3.2 m wide has an area of 4.5 x 3.2 = 14.4 m² (155 ft²). For L-shaped rooms, split the space into rectangles, calculate each one, and add the results together.
