Square Meter Calculator
Calculate area in square meters from various units and shapes. Convert between square meters, square feet, square yards, acres, and hectares. See also our Square Footage Calculator, Square Yard Calculator, and Area Calculator.
How to Use the Square Meter Calculator
Select the shape of your area (rectangle, triangle, circle, or trapezoid). Choose your measurement unit — the calculator accepts meters, centimeters, feet, inches, or yards. Enter the dimensions for your chosen shape. Click Calculate to see the area in square meters along with conversions to square feet, square yards, acres, and hectares. This calculator is useful for real estate, flooring, landscaping, and any project requiring metric area measurements.
Formula
Rectangle: Area = Length x Width
Triangle: Area = 0.5 x Base x Height
Circle: Area = π x Radius²
Trapezoid: Area = 0.5 x (Side A + Side B) x Height
1 sq meter = 10.7639 sq ft = 1.19599 sq yd
1 hectare = 10,000 sq meters = 2.471 acres
Example Calculation
Room: 10 m x 8 m (rectangle)
Area = 10 x 8 = 80 square meters
In square feet: 80 x 10.7639 = 861.11 sq ft
In square yards: 80 x 1.19599 = 95.68 sq yd
In acres: 80 / 4046.86 = 0.0198 acres
In hectares: 80 / 10000 = 0.008 hectares

Frequently Asked Questions
How do I convert square feet to square meters?
Divide square feet by 10.7639 to get square meters. For example, a 1,000 sq ft apartment is 1000 / 10.7639 = 92.9 square meters. Alternatively, multiply square feet by 0.0929 for the same result. This conversion is commonly needed for international real estate listings.
What is the difference between square meters and meters squared?
They mean the same thing mathematically. "Square meters" (m²) is the standard unit of area in the metric system. "Meters squared" describes the operation (length in meters multiplied by width in meters). Both refer to the area of a surface measured in the metric system.
How many square meters is a typical house?
Average house sizes vary by country: US homes average 200 m² (2,150 sq ft), UK homes average 76 m² (818 sq ft), Australian homes average 189 m² (2,034 sq ft), and apartments in major cities average 50-80 m². A standard single-car garage is about 15-20 m².
How do I measure an irregularly shaped room?
Break the room into regular shapes (rectangles, triangles). Measure each section separately, calculate their areas, and add them together. For L-shaped rooms, divide into two rectangles. For rooms with alcoves, calculate the main rectangle and add the alcove area. Subtract areas for built-in closets or columns.
What is a hectare in square meters?
One hectare equals 10,000 square meters (100m x 100m). It's roughly 2.47 acres or about the size of a standard soccer field (which is approximately 0.7 hectares). Hectares are commonly used for measuring land area in most countries outside the United States.
How do I calculate square meters for flooring?
Measure the room length and width in meters (or convert from feet by dividing by 3.281). Multiply length by width for rectangular rooms. Add 10% for waste and cuts. For example, a 5m x 4m room needs 20 m² of flooring, plus 10% waste = 22 m² to purchase.
