Square footage is a measurement of area expressed in square feet (sq ft). It represents the amount of two-dimensional space and is commonly used in real estate, construction, and interior design to quantify the size of rooms, properties, and land.
The formula for calculating square footage is:
Where:
Explanation: For rectangular or square areas, simply multiply the length by the width to get the total area in square feet.
Details: Accurate square footage calculation is essential for determining material quantities, property valuation, space planning, and compliance with building codes and regulations.
Tips: Enter both length and width measurements in feet. Ensure measurements are accurate and in the same unit (feet). The calculator will automatically compute the area in square feet.
Q1: How do I calculate square feet for irregular shapes?
A: For irregular shapes, divide the area into smaller regular shapes (rectangles, triangles), calculate each area separately, then sum them together.
Q2: How do I convert square feet to other area units?
A: 1 square foot = 144 square inches, 1 square foot ≈ 0.0929 square meters, 1 square foot ≈ 0.00002296 acres.
Q3: Does square footage include wall thickness?
A: Typically, interior measurements exclude wall thickness, while exterior measurements include it. Always clarify which standard is being used.
Q4: How accurate should my measurements be?
A: For most purposes, measurements to the nearest 1/4 foot (3 inches) are sufficient. For precise work, measure to the nearest inch or centimeter.
Q5: Can I use this calculator for metric measurements?
A: This calculator expects inputs in feet. Convert metric measurements to feet first (1 meter = 3.28084 feet) before calculating.
