Square Footage Formula:
| From: | To: |
Square footage is calculated by multiplying the length of an area by its width. This formula applies to rectangular or square-shaped areas and provides the total area in square feet.
The calculator uses the square footage formula:
Where:
Explanation: This simple multiplication gives the area of a rectangular space in square feet, which is essential for various construction, real estate, and design applications.
Details: Accurate square footage calculation is crucial for determining material quantities, property valuation, space planning, and compliance with building codes and regulations.
Tips: Enter length and width measurements in feet. Both values must be positive numbers. The calculator will automatically compute the square footage when you click "Calculate".
Q1: Can this calculator be used for non-rectangular areas?
A: No, this calculator is specifically designed for rectangular areas. For irregular shapes, the area should be divided into rectangular sections and calculated separately.
Q2: What if my measurements are in different units?
A: Convert all measurements to feet before entering them into the calculator. For example, if you have inches, divide by 12 to convert to feet.
Q3: How accurate should my measurements be?
A: For most applications, measurements to the nearest 1/4 inch (0.02 feet) are sufficient. For precise work, measure to the nearest 1/8 inch (0.01 feet).
Q4: Does square footage include wall thickness?
A: Typically, interior square footage measurements are taken from the inside surfaces of walls, while exterior measurements include wall thickness. Always clarify which standard is being used.
Q5: How is square footage used in real estate?
A: In real estate, square footage helps determine property value, compare similar properties, calculate price per square foot, and ensure accurate listing information.
