1. What is Square Footage Calculation?

Square footage calculation measures the total area of a house by summing the areas of all individual rooms. It's an essential metric in real estate, construction, and home improvement projects.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{Length}_i \) — Length of room i in feet
• \( \text{Width}_i \) — Width of room i in feet
• \( n \) — Total number of rooms

Explanation: The calculator sums the area of each room (length × width) to determine the total square footage of the house.

3. Importance of Square Footage Calculation

Details: Accurate square footage is crucial for property valuation, renovation planning, furniture placement, and compliance with building codes. It affects property taxes, insurance premiums, and resale value.

4. Using the Calculator

Tips: Measure each room's length and width in feet. Add all rooms using the "Add Another Room" button. Ensure measurements are accurate and in the same unit (feet).

5. Frequently Asked Questions (FAQ)

Q1: Should I include closets and hallways?
A: Yes, all livable space should be included. Measure each distinct area separately and add them to the total.

Q2: How do I measure irregularly shaped rooms?
A: Divide irregular rooms into rectangular sections, calculate each section's area, then sum them together.

Q3: Do I include unfinished spaces like basements?
A: Typically, only finished, heated living spaces are included in official square footage calculations for real estate purposes.

Q4: How accurate should measurements be?
A: For most purposes, measurements to the nearest inch (0.01 feet) provide sufficient accuracy.

Q5: Does square footage include multiple floors?
A: Yes, total square footage includes all floors. Calculate each floor separately and sum them for the total.
