1. What is Square Footage?

Square footage is a measurement of area expressed in square feet (sq ft). It represents the total floor space of a room or building and is commonly used in real estate, construction, and interior design.

2. How to Calculate Square Footage

The basic formula for calculating square footage is:

Where:

• Length — The longest dimension of the area (in feet)
• Width — The shorter dimension perpendicular to the length (in feet)

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 (flooring, paint), space planning, property valuation, 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 footage for an L-shaped room?
A: Divide the space into rectangular sections, calculate each separately, then add them together.

Q2: Does square footage include wall thickness?
A: Typically no - square footage refers to interior living space. For exterior measurements, we use "gross square footage."

Q3: How do you convert square feet to square meters?
A: Multiply square feet by 0.092903 to get square meters.

Q4: Should closets be included in square footage?
A: Yes, all interior spaces with floor area should be included in the total square footage.

Q5: How accurate should my measurements be?
A: For most purposes, measuring to the nearest inch is sufficient. Professional measurements often use laser measures for precision.
