Square Meter Calculator
Calculate square meters from metric room dimensions, triangles, or circles.
This page keeps square meters as the main result and includes quick conversions to square feet, square yards, acres, and hectares.
Results
This is a quick square meter calculator for simple areas. Use trade-specific calculators for flooring boxes, tile waste, roof pitch, or material quantities.
How to use this calculator
- 01Choose rectangle / room, triangle, or circle.
- 02Enter the dimensions in meters. Decimals are fine, such as 3.5 m.
- 03Read the m² result as the primary area.
- 04Use the square feet, square yards, acres, and hectares rows when you need a quick conversion.
If your measurements are in feet and inches, use the Square Footage Calculator. It keeps square feet primary and includes a square meter conversion. For square-yard area conversions, use the Square Yard Calculator.
Understanding the math
Square meters measure area. Enter linear dimensions in meters, then use the area formula for the selected shape.
rectangle_area = length x width triangle_area = base x height / 2 circle_area = pi x (diameter / 2)^2 square_feet = square_meters x 10.7639104 square_yards = square_meters / 0.83612736 acres = square_meters / 4046.8564224 hectares = square_meters / 10000

Frequently asked questions
How to calculate in square meters?
For a rectangle or room, multiply length by width in meters. Triangles use base x height / 2, and circles use pi x radius squared.
How to calculate square meter of a room?
Measure the room length and width in meters, then multiply them. For an irregular room, split it into smaller rectangles and add the areas.
How to calculate square feet into square meters?
Multiply square feet by 0.09290304. For example, 100 sq ft is about 9.29 square meters.
What size is 1 square meter?
One square meter is the area of a square that is 1 meter long and 1 meter wide.
Can I use this calculator with feet or inches?
This page is built for meters and square meters. For feet-and-inches inputs, use the Square Footage Calculator, which also shows a square meter conversion.
