Square Feet Formula:
| From: | To: |
The square feet calculation formula is a simple mathematical equation used to determine the area of a rectangular space. It multiplies the length by the width of an area to calculate the total square footage.
The calculator uses the square feet formula:
Where:
Explanation: This formula calculates the area of a rectangle by multiplying its length by its width. For irregular shapes, the area can be calculated by dividing the space into rectangular sections.
Details: Accurate square footage calculation is essential for real estate transactions, construction projects, flooring installation, painting estimates, and space planning. It helps determine material quantities, project costs, and property values.
Tips: Enter the 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 I use different units of measurement?
A: This calculator specifically uses feet. If you have measurements in other units (inches, yards, meters), convert them to feet first before calculating.
Q2: How do I calculate square feet for irregular shapes?
A: Divide irregular shapes into smaller rectangles, calculate each area separately, then sum all the areas together.
Q3: What's the difference between square feet and linear feet?
A: Square feet measure area (length × width), while linear feet measure length in a straight line.
Q4: How accurate should my measurements be?
A: For most applications, measuring to the nearest inch (0.08 feet) is sufficient. For precise work, measure to the nearest 1/4 inch (0.02 feet).
Q5: Can this formula be used for triangular or circular areas?
A: No, this formula is specifically for rectangular areas. Triangles use (base × height)/2 and circles use π × radius².
