How to measure an area in square meters

Updated February 21, 2017

If you are planning a landscaping project or a home project such as installing flooring, you will first need to know the size of the area that you will be working with. A square meter is a metric measurement of area. While some people are more familiar with square footage, some manufacturers may package their materials in terms of square meters rather than square feet. In this case, you would need to know the amount of square meters that you have in order to purchase the correct amount of materials.

If the area involved in your project is square or a rectangular, measure the length and width of the area, using a metric tape measure or a meter stick.

Multiply the length, in meters, times the width, in meters. That will give you the area of the square or rectangle in square meters.

If the area involved is not square or rectangular, sketch the area to scale on a piece of graph paper. You can make sure that it is to scale by allowing each division on the grid to equal a certain number of meters.

Break up the sketch into rectangles, squares, triangles, and even circles, if necessary.

Apply the appropriate meter-based formulas to each shape on the graph to determine the area of each shape in square meters. Multiply length times width for squares and rectangles. Multiply base times height and divide by two for triangles. Measure from the centre of a circle to its outer edge to find the radius; then multiply the radius times itself and multiply that figure by 3.14, which is "pi."

Add the areas of each shape to find the square meters of the entire area.


If you don't have a metric tape measure or meter stick, you can measure the area in feet. Then convert the square feet to square meters by multiplying the square footage by 0.09294.
