1. What is Square Footage?

Square footage is a measurement of area, specifically the total area of a space measured in square feet. It's commonly used in real estate, construction, and interior design to quantify the size of a house, apartment, or individual rooms.

2. How to Calculate Square Footage

The basic formula for calculating square footage is:

For a house with multiple rooms:

• Measure the length and width of each room in feet
• Multiply length by width for each room to get room area
• Sum the areas of all rooms to get total square footage

Note: For irregularly shaped rooms, divide them into rectangular sections and calculate each separately.

3. Why Calculate Square Footage?

Importance: Square footage is crucial for determining property value, calculating material needs for flooring or painting, estimating heating/cooling requirements, and complying with building codes.

5. Frequently Asked Questions (FAQ)

Q1: Should I include closets and hallways?
A: Yes, all living spaces should be included in your calculations. Measure each area separately if they're different sizes.

Q2: How accurate should measurements be?
A: For most purposes, measuring to the nearest inch (0.08 feet) is sufficient. For precise calculations (like flooring), measure to 1/4 inch.

Q3: Do I include wall thickness in measurements?
A: For interior square footage, measure from the interior surface of walls. For exterior measurements, include wall thickness.

Q4: How do I measure irregularly shaped rooms?
A: Divide the space into rectangular sections, calculate each separately, then sum the areas.

Q5: What's the difference between gross and net square footage?
A: Gross includes all space (walls, mechanical areas), while net is just usable space. This calculator computes net square footage.
