1. What is Square Footage?

Square footage is a measurement of area, specifically the area of a two-dimensional space measured in square feet. It's commonly used in real estate, construction, and interior design to quantify the size of rooms, buildings, or plots of land.

2. How to Calculate Square Footage

The basic formula for calculating square footage is:

Where:

• Length — Measurement in feet of one side of the area
• Width — Measurement in feet of the perpendicular side

For irregular shapes: Divide the space into rectangular sections, calculate each separately, then sum the results.

3. Importance of Square Footage Calculation

Details: Accurate square footage measurements are essential for determining material quantities, property valuation, space planning, and compliance with building codes.

4. Using the Calculator

Tips: Measure the length and width in feet, enter both values. For accuracy, measure to the nearest inch (convert inches to decimal feet by dividing by 12).

5. Frequently Asked Questions (FAQ)

Q1: How do you calculate square feet from inches?
A: First convert inches to feet by dividing by 12, then multiply length × width in feet.

Q2: How many square feet is a 12×12 room?
A: 144 square feet (12 × 12 = 144).

Q3: Does square footage include wall thickness?
A: It depends on context. For interior spaces, typically measure inside walls. For exterior measurements, include wall thickness.

Q4: How accurate should square footage measurements be?
A: For most purposes, measuring to the nearest inch (0.08 feet) is sufficient.

Q5: How do you calculate square footage for a triangle?
A: Use the formula: (Base × Height) ÷ 2, with both measurements in feet.
