1. What is Square Footage?

Square footage is a measurement of area, calculated by multiplying length by width. It's commonly used in real estate, construction, and interior design to quantify the size of a space.

2. How Does the Calculator Work?

The calculator uses the square footage formula:

Where:

• \( SF \) — Square footage (sq ft)
• \( L \) — Length in feet
• \( W \) — Width in feet

Explanation: The calculator converts any inch measurements to decimal feet (inches ÷ 12) before performing the multiplication.

3. Importance of Square Footage Calculation

Details: Accurate square footage calculation is essential for determining material quantities, estimating costs, planning space utilization, and property valuation.

4. Using the Calculator

Tips: Enter length and width measurements in feet and optional inches. All values must be non-negative numbers. The calculator will automatically convert inches to decimal feet.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure irregularly shaped rooms?
A: Divide the space into rectangular sections, calculate each area separately, then sum the results.

Q2: Does square footage include wall thickness?
A: Typically, interior measurements are taken from inside wall to inside wall, excluding wall thickness.

Q3: How accurate should my measurements be?
A: For most purposes, measuring to the nearest inch provides sufficient accuracy.

Q4: Can I calculate square footage for triangular areas?
A: This calculator is for rectangular areas. For triangles, use: Area = (base × height) ÷ 2.

Q5: How do I convert square feet to square meters?
A: Multiply square feet by 0.0929 to get square meters.
