1. What is Square Footage Calculation?

Square footage calculation measures the total area of a house or building by summing the areas of individual rooms. It's essential for real estate valuation, construction planning, and interior design projects.

2. How Does the Calculator Work?

The calculator uses the square footage formula:

Where:

• \( SF \) — Total square footage
• \( L_i \) — Length of room i (feet)
• \( W_i \) — Width of room i (feet)
• \( n \) — Number of rooms

Explanation: The calculator multiplies length by width for each room and sums all room areas to get the total square footage.

3. Importance of Square Footage Calculation

Details: Accurate square footage calculation is crucial for property valuation, construction cost estimation, space planning, and compliance with building codes and regulations.

4. Using the Calculator

Tips: Enter the number of rooms first, then provide length and width measurements for each room in feet. All measurements must be positive values.

5. Frequently Asked Questions (FAQ)

Q1: Should I include closets and hallways?
A: Yes, for total living area calculation, include all enclosed spaces. For specific purposes, consult relevant measurement standards.

Q2: How accurate should measurements be?
A: For real estate purposes, measurements should be precise to the nearest inch. For rough estimates, rounding to the nearest foot is acceptable.

Q3: Do I measure from inside or outside walls?
A: Interior measurements are taken from the inside of exterior walls for living area calculations.

Q4: How do I handle irregularly shaped rooms?
A: Break irregular shapes into smaller rectangles, calculate each area separately, then sum them together.

Q5: What's the difference between gross and net square footage?
A: Gross includes all areas within exterior walls, while net excludes walls, mechanical spaces, and other non-livable areas.
