Convert among square inch, square foot, square yard and square meter Multiply your Length × Width to get your area. Note: If your measurements aren't in feet, convert them to feet first using the instructions below or the length converter. This yields a product called the area, which is expressed in square feet (or square inches if you are calculating a much smaller space, such as a dollhouse). The formula for the area of a rectangular room is width x length, as shown in the figure below: This is the equation used in our square footage calculator as well. The next step in how to calculate square footage is to plug your measurements into the square footage formula: L x W = A (in square feet) To find square feet, multiply the length measurement in feet by the width measurement in feet. Note that if you measure the room in inches, the result will be in square inches. Now, … If you are measuring a square or rectangle area, multiply length times width; Length x Width = Area. To calculate square footage of an oddly shaped area, for example an L shaped area. Calculating square footage of your area For a square or rectangular area, measure the Width and Length in feet. Simply multiply the length and width of the area.

If you measure it … For other area shapes, see formulas below to calculate Area (ft 2) = Square Footage. Therefore, if you can measure the width and length of the room, you can easily calculate the square footage by simply multiplying the two measurements. Start by splitting the area into two separate sections making square or rectangle of both sections. The formula for square footage area used will be in accordance with the shape.

For example, to calculate square footage of a room in square (2) or rectangle shape. Calculate the Area as Square Footage.
