Floor Area Converter
Convert floor area between square meters, square feet, square yards, and more. Free online floor area converter for real estate, interior design, and construction planning.
Floor Area Measurement
Floor area measurements determine the size of rooms, buildings, and properties. Different countries use different units. The US uses square feet while most other countries use square meters. Accurate conversions enable international real estate comparisons.
Area Calculation Formula
Rectangle: Area = Length × Width
Square: Area = Side²
Triangle: Area = 0.5 × Base × Height
Circle: Area = π × radius²
Measure length and width at the longest points. For irregular rooms, divide into rectangles and calculate separately. Add all areas for total floor space.

Room Size Examples
Example 1: Standard Bedroom
Dimensions: 12 ft × 14 ft
Area: 168 sq ft
Square meters: 168 × 0.0929 = 15.6 m²
Square yards: 168 / 9 = 18.7 yd²
Example 2: Living Room
Dimensions: 5 m × 6 m
Area: 30 m²
Square feet: 30 × 10.764 = 323 sq ft
Square yards: 30 / 0.836 = 35.9 yd²
Example 3: Whole House
Total: 2,500 sq ft
Square meters: 2,500 × 0.0929 = 232 m²
Acres: 2,500 / 43,560 = 0.057 acres
Typical 3-4 bedroom home
Example 4: Apartment
Total: 85 m²
Square feet: 85 × 10.764 = 915 sq ft
Typical 2-bedroom apartment
Common in European cities

Location affects price more than size
Frequently Asked Questions
How do I convert square feet to square meters?
Multiply square feet by 0.0929. For quick estimation, divide by 10 and add 7%. Example: 1,000 sq ft × 0.0929 = 92.9 m². Or 1,000 / 10 = 100, minus 7% = 93 m².
How do I convert square meters to square feet?
Multiply square meters by 10.764. For quick estimation, multiply by 10 and add 8%. Example: 50 m² × 10.764 = 538 sq ft. Or 50 × 10 = 500, plus 8% = 540 sq ft.
Do I include wall thickness in measurements?
Standard practice measures from exterior wall surfaces. This includes interior wall thickness in room dimensions. Some standards measure from interior surfaces. Check local conventions.
How much flooring should I order?
Order 5-10% extra for simple rooms. Add 10-15% for complex layouts. Diagonal patterns need 15-20% extra. Keep extras for future repairs. Different dye lots may not match.
