1. What is Gross Building Size?

Gross Building Size is the total sum of all floor areas in a building. It's a fundamental metric in architecture, real estate, and construction for determining the overall scale of a structure.

2. How Does the Calculator Work?

The calculator uses the simple summation formula:

\[ \text{Size} = \text{Floor 1 Area} + \text{Floor 2 Area} + \text{Floor 3 Area} + \text{Floor 4 Area} \]

Where:

All areas are measured in square feet (sq ft)
Only floors with values entered are included in the calculation
Decimal values are accepted for precise measurements

3. Importance of Size Calculation

Details: Accurate building size calculation is essential for construction planning, zoning compliance, real estate valuation, and building code requirements.

4. Using the Calculator

Tips: Enter the area for each floor in square feet. You can calculate with just one floor or up to four floors. Values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's included in gross building size?
A: Typically includes all enclosed spaces on all floors, measured from exterior walls.

Q2: How does this differ from net area?
A: Gross area includes all space (walls, mechanical areas), while net area is just usable space.

Q3: Should I include basement areas?
A: Yes, if they're finished spaces. Check local regulations for specific requirements.

Q4: What about areas with different ceiling heights?
A: This calculator uses simple area summation. For volume calculations, a different approach is needed.

Q5: How precise should measurements be?
A: For most purposes, measuring to the nearest square foot is sufficient.
