Square Footage Formula:
| From: | To: |
Square footage calculation is a fundamental measurement in construction and real estate that determines the area of a space. It's calculated by multiplying the length by the width of a rectangular area, providing the total area in square feet.
The calculator uses the simple area formula:
Where:
Explanation: The calculator accepts measurements in feet and inches, converts inches to decimal feet (inches ÷ 12), then multiplies length by width to get the total square footage.
Details: Accurate square footage calculation is essential for construction planning, material estimation, cost calculation, real estate valuation, and space planning. It helps determine how much flooring, paint, or other materials are needed for a project.
Tips: Enter length and width measurements in feet and inches. For inches, you can use decimal values (e.g., 6.5 for 6½ inches). All values must be non-negative numbers.
Q1: Why calculate square footage in construction?
A: Square footage calculation helps estimate material quantities, project costs, and space requirements for construction projects, ensuring accurate budgeting and planning.
Q2: How do I measure irregularly shaped areas?
A: For irregular shapes, break the area into smaller rectangles, calculate each section's square footage separately, then sum the results.
Q3: What's the difference between square feet and square meters?
A: Square feet is the imperial unit of area, while square meters is the metric unit. 1 square meter equals approximately 10.764 square feet.
Q4: Should I include wall thickness in measurements?
A: For interior space calculations, measure inside dimensions. For exterior or structural calculations, include wall thickness as needed.
Q5: How accurate should my measurements be?
A: For most construction purposes, measurements should be accurate to within ¼ inch. For precise material ordering, even greater accuracy may be required.
