1. What is Square Footage Calculation?

Square footage calculation is the process of determining the total livable area of a house according to realtor standards. It involves measuring and summing up all habitable spaces while excluding non-livable areas like garages, unfinished basements, and porches.

2. How Does the Calculator Work?

The calculator uses the standard realtor formula:

\[ \text{Total Square Footage} = \sum \text{(Length} \times \text{Width)} \text{ of all livable areas} \]

Where:

Length × Width — Area calculation for each room/space
∑ — Summation of all individual areas
Livable Areas — Habitable spaces only (bedrooms, living rooms, kitchens, etc.)

Explanation: The calculation follows ANSI Z765 standards, measuring from exterior walls and including only finished, heated, and habitable spaces.

3. Importance of Accurate Square Footage

Details: Accurate square footage is crucial for property valuation, comparative market analysis, listing prices, and buyer decision-making. It directly impacts property appraisal and marketability.

4. Using the Calculator

Tips: Enter the total livable area in square feet. Ensure measurements follow standard realtor guidelines - measure from interior wall to interior wall and include only finished, heated spaces.
