1. What is Square Feet?

Square feet (ft²) is a unit of area measurement equal to a square measuring one foot on each side. It's commonly used in real estate, construction, and interior design to measure floor space.

2. How Does the Calculator Work?

The calculator uses the simple area formula:

Where:

• \( length \) — Measurement in feet
• \( width \) — Measurement in feet

Explanation: The area of a rectangle is calculated by multiplying its length by its width.

3. Importance of Square Feet Calculation

Details: Calculating square footage is essential for determining property value, planning construction projects, purchasing materials like flooring or paint, and complying with building codes.

4. Using the Calculator

Tips: Enter both length and width in feet. Measurements can be in decimals for precise calculations. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I convert inches to square feet?
A: First convert inches to feet (divide by 12), then multiply length by width. Or multiply inches together and divide by 144.

Q2: What's the difference between square feet and linear feet?
A: Square feet measures area (length × width), while linear feet measures length only.

Q3: How many square feet are in an acre?
A: One acre equals 43,560 square feet.

Q4: How do I calculate square feet for irregular shapes?
A: Divide the space into regular shapes (rectangles, triangles), calculate each separately, then sum the areas.

Q5: Why is square footage important in real estate?
A: It's a key factor in property valuation, pricing comparisons, and determining functional living space.
