1. What is Square Footage?

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

2. How to Calculate Square Feet

The formula for calculating square feet is simple:

Where:

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

Example: A room that is 12 feet long and 10 feet wide has an area of 120 square feet (12 × 10 = 120 sq ft).

3. Importance of Square Foot Calculation

Details: Calculating square footage is essential for determining material quantities (like flooring or paint), comparing property sizes, calculating property values, and ensuring compliance with building codes.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: How do you calculate square feet for irregular shapes?
A: Divide the space into rectangular sections, calculate each separately, then sum the areas.

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

Q3: How many square feet are in a square yard?
A: There are 9 square feet in 1 square yard (3 feet × 3 feet).

Q4: Does square footage include wall thickness?
A: It depends on context. Interior measurements exclude walls, while exterior measurements include them.

Q5: How accurate should square footage measurements be?
A: For most purposes, measuring to the nearest 1/4 foot (3 inches) is sufficient.
