US Measurement Methods

Gross Living Area (GLA)

The most common residential standard. Measures finished, above-grade living space. Key rules:

  • Measure exterior walls
  • Must be finished space
  • Must have heating/cooling
  • Below-grade space listed separately

Common Variations

  • Heated square feet: Only HVAC-served areas
  • Under roof: Everything under the roofline
  • Rentable sq ft: Commercial—includes share of common areas
  • Usable sq ft: Commercial—actual space tenant occupies

International Comparison

European (Square Meters)

Most European countries measure "living area" in square meters, but definitions vary:

  • Germany: Balconies count 25-50%, basement storage may count
  • France (Loi Carrez): Only counts space with ceiling >1.8m
  • UK (RICS): Gross Internal Area includes all internal space

Asian Markets

  • Japan: Tsubo (1 tsubo = 3.3 sq m) traditional, m² official
  • Korea: Pyeong (1 pyeong = 3.3 sq m)
  • Hong Kong: Square feet (may include common areas in condos)

Price Per Square Foot/Meter

Comparing price per area helps evaluate value:

Calculation

Price per sq ft = Total price ÷ Square footage

Example: $500,000 for 2,000 sq ft = $250/sq ft

Typical Ranges (2024)

  • US national average: ~$150-200/sq ft
  • Manhattan: $1,500-2,500/sq ft
  • London (Central): £1,000-2,000/sq ft
  • Paris: €10,000-15,000/sq m

Conclusion

Real estate area measurement varies by country, region, and property type. In the US, square footage typically includes finished living space; in Europe, square meters may include or exclude various spaces depending on national standards. Always clarify what's included, and when comparing international properties, remember that 1 square meter equals about 10.76 square feet.
