Square Footage Formula:
| From: | To: |
Square footage is calculated by multiplying the length of an area by its width. For rectangular or square spaces, this provides the total area in square feet, which is a standard measurement for property size in real estate and construction.
The calculator uses the simple area formula:
Where:
Explanation: This formula calculates the area of a rectangular space. For irregularly shaped rooms, the space should be divided into rectangular sections and their areas summed.
Details: Accurate square footage calculation is essential for property valuation, determining material requirements for flooring or painting, space planning, and complying with building codes and real estate regulations.
Tips: Measure the length and width in feet using a tape measure. Enter both values as positive numbers. For accuracy, measure at multiple points in irregular rooms and use the average dimensions.
Q1: How do you measure irregularly shaped rooms?
A: Divide the space into rectangular sections, calculate each area separately, then sum all the areas together for the total square footage.
Q2: Should I include closets and alcoves in measurements?
A: Yes, all livable space within the exterior walls should be included in the total square footage calculation.
Q3: Do you measure from inside or outside walls?
A: For interior space calculations, measure from the interior surface of the walls. For exterior measurements (like for siding), measure from the exterior.
Q4: How accurate do measurements need to be?
A: For most purposes, measurements to the nearest inch or half-foot are sufficient. For construction or real estate listings, greater precision may be required.
Q5: How is square footage different from acreage?
A: Square footage measures area in square feet (imperial system), while acreage measures land area where 1 acre = 43,560 square feet.
