Area of a Room

The Area of a Room calculator helps you compute the are (square meters or square feet) of a room based on the room's shape and dimensions.

Calculating Area

The area of a room may be difficult to estimate.  This calculator has buttons to help you compute the area.  To compute the area or the room, you must first identify the shape of the area.  The common choices follow.  

• Rectangular Room - Calculate area for simple four sided rectangle with squared corners.
• Quadrilateral Room - Calculate area for quadrilateral  which is an area with four straight sides with different angle corners.
• Triangular Room - Calculate the area of a triangle
• Polygon Room - Calculates the area of regular polygons with three or more sides where the sides are the same length with the same angles in the corners. To compute the area of a polygon, one needs the length of a side (s) and the number of sides (n).
• Circular Room - Calculate the area of a circle with a radius
• Elliptical Room - Calculate the area of an ellipse, oval shaped or flattened circle. 

Note:  The default inputs to the calculators are meters.  However, this can be toggled via the pull-down menu to feet, inches, yards or other length units.  The default area results are in square meters.  These can be automatically converted to square feet and other area units via the pull-down menu.

How Area is Used

The calculator helps you compute the square footage of an area, but when will I need it?  One big use of square footage is when you are thinking about buying or selling a house.  Square footage is one of the basic metrics used in any listing.    Many jobs, especially Do-It-Yourself jobs, require that you know the square footage of an area before you can intelligently buy supplies.  This is common inside the house and office and outside in landscaping.  Here are few related calculators that are use square footage in calculating materials needed for jobs.
