Square Footage Formula:
| From: | To: |
Square footage calculation measures the area of a space by multiplying its length by its width. It's a fundamental measurement used in construction, real estate, and interior design to quantify the size of rooms, buildings, and properties.
The calculator uses the square footage formula:
Where:
Explanation: The formula calculates the area of a rectangular space by multiplying its length by its width. Height is not needed for square footage calculation as it measures area, not volume.
Details: Accurate square footage measurement is essential for determining property value, planning construction projects, calculating material requirements, and complying with building codes and regulations.
Tips: Enter length and width in feet. Both values must be positive numbers. For irregularly shaped rooms, divide them into rectangular sections and calculate each separately.
Q1: Why isn't height included in square footage calculation?
A: Square footage measures area (two-dimensional space), while height is used for calculating volume (three-dimensional space). For floor area, only length and width are needed.
Q2: How do I measure irregularly shaped rooms?
A: Divide the space into rectangular sections, calculate each area separately, then sum all the areas to get the total square footage.
Q3: What's the difference between square feet and cubic feet?
A: Square feet measure area (length × width), while cubic feet measure volume (length × width × height).
Q4: How accurate should my measurements be?
A: For most purposes, measuring to the nearest inch (0.08 feet) is sufficient. For precise calculations, measure to the nearest 1/4 inch.
Q5: Can I use this calculator for metric measurements?
A: This calculator uses feet as the unit of measurement. For metric calculations, convert meters to feet (1 meter = 3.28084 feet) or use a square meter calculator.
