1. What is Square Footage Calculation?

Square footage calculation determines the total area of a building by summing the areas of all floors. It's essential for real estate valuation, construction planning, and space utilization analysis.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Length — The longest dimension of each floor (feet)
• Width — The shorter dimension of each floor (feet)
• Σ — Summation of all floor areas

Explanation: The calculation multiplies length by width for each floor and sums these values to get the total square footage.

3. Importance of Square Footage Calculation

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

4. Using the Calculator

Tips: Enter the number of floors, then provide length and width measurements for each floor in feet. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Should I include basement areas?
A: Yes, if the basement is finished and habitable. Unfinished basements are typically not included in living area calculations.

Q2: How do I measure irregularly shaped floors?
A: Divide irregular shapes into rectangles, calculate each area separately, then sum them together.

Q3: Are exterior walls included in measurements?
A: Standard practice is to measure from the interior surface of exterior walls for interior square footage.

Q4: What's the difference between gross and net square footage?
A: Gross square footage includes all space within exterior walls, while net square footage excludes areas like walls and mechanical spaces.

Q5: How accurate should measurements be?
A: For most purposes, measurements to the nearest inch or centimeter provide sufficient accuracy.
