How to figure out square footage from a floor plan.

Multiply the width by the length and voila. The square footage of a room measuring 12 feet wide by 12 feet long is 144 square feet. The second method allows you to calculate the total area of the footprint of the plan. Convert among square inch square foot square yard and square meter.

Floor plans are drawn to scale in comparison to the space being created by the plan. Calculating floor area can be difficult especially if the rooms have irregular shapes. Just break out your measuring tape or a laser measure to get its length and width. Draw your floor plan and let our powerful floor area calculator do the calculations for you automatically.

To calculate this you simply multiply the width by the height. If you are measuring a square or rectangle area multiply length times width. There are two ways to calculate the square footage from the exterior of the structure instead. Calculate the area as square footage.

If you have a paper floor plan and need to calculate the square footage yourself one convenient method is to overlay your plan with tracing paper trace the outline of the outer limits of the plan and then subdivide the plan into several rectangles. The square footage calculator estimates the square footage of a lot house or other surfaces in several common shapes. The finished square footage of each level is the sum of the finished areas on that level measured at floor level to the exterior finished surface of the outside wall or to the center line of a dividing wall in a duplex or town home configuration. You have the square footage.

Say a room is 20 feet wide by 13 feet. Different types of projects and industries require different types of area calculations. A room that is 10 feet by 12 feet for example provides 120 square feet of living space. If the surface is complex in shape it may be possible to section the surface into simple shapes and add their square footages together.

Length x width area. 12ft 12ft 144 sq ft. Square footage for a circular area measure the diameter of your circle in feet. Typically it states the square footage for the total space and provides a breakdown of that square footage by living area within the building or home.
