Real Estate Measurements: Sq Ft, Acres, Hectares
A complete guide to understanding real estate area measurements, including square feet, acres, hectares, and square meters with conversion formulas.

Key Real Estate Units
Real estate uses a handful of area units depending on the property type and country. In the United States, homes are measured in square feet, lots and small parcels in acres, and large tracts in sections (640 acres). Most other countries use square metersfor homes and hectares for land. Understanding these units and how they relate to each other is essential for comparing properties across markets.
Essential Conversion Formulas
- 1 acre = 43,560 square feet = 4,046.86 square meters = 0.4047 hectares
- 1 hectare = 10,000 square meters = 2.471 acres = 107,639 square feet
- 1 square foot = 0.092903 square meters
- 1 square meter = 10.7639 square feet
- 1 section = 640 acres = 259 hectares = 1 square mile
Worked Examples
Example 1: Convert a 2,500 sq ft home to square meters
- Step 1: Multiply by 0.092903.
- Step 2: 2,500 × 0.092903 = 232.26 square meters.
- Result: A 2,500 sq ft home is about 232 m².
Example 2: Convert a 0.75-acre lot to square feet
- Step 1: Multiply by 43,560.
- Step 2: 0.75 × 43,560 = 32,670 square feet.
- Result: A 0.75-acre lot is 32,670 sq ft.
Example 3: Convert 5 hectares to acres
- Step 1: Multiply by 2.471.
- Step 2: 5 × 2.471 = 12.355 acres.
- Result: 5 hectares ≈ 12.36 acres.

How Home Square Footage Is Measured
In the US, the most common standard is to measure the gross living area (GLA), which includes all finished, heated living space measured from the exterior walls. The following are typically excluded:
- Garages (attached or detached)
- Unfinished basements or attics
- Covered porches and patios
- Rooms with ceiling heights below a minimum (often 7 feet)
Standards vary by region and appraiser. The ANSI standard (American National Standards Institute) provides guidelines, but not all real estate listings follow them consistently. When comparing properties, ask how the square footage was measured.
Real-World Applications
Comparing International Listings
A 120 m² apartment in Paris equals about 1,292 square feet. A “spacious” apartment in Tokyo at 80 m² (861 sq ft) might seem small by American standards. Converting quickly helps you calibrate expectations when searching internationally.
Land Purchases
Rural land in the US is often priced per acre, while European farmland is priced per hectare. A farm listed at €15,000 per hectare translates to about €6,070 per acre (dividing by 2.471). Read more about hectares in our hectare guide.
Property Tax Assessment
Property taxes are often based on the assessed value, which correlates with lot size and building area. Understanding exactly how many square feet or acres you own helps you verify tax assessments.
Frequently Asked Questions
How many square feet are in an acre?
There are exactly 43,560 square feet in one acre. An acre is roughly the size of a football field without the end zones.
How do I convert square feet to square meters?
Multiply square feet by 0.092903 to get square meters. For example, 2,000 sq ft × 0.092903 = 185.8 square meters.
How many acres are in a hectare?
There are approximately 2.471 acres in one hectare. One acre equals about 0.4047 hectares.
How is the square footage of a house measured?
In the US, square footage typically includes all finished, heated living space measured from the exterior walls. Garages, unfinished basements, and porches are usually excluded. Methods vary by region, so check local standards.
