1. What is Outside Square Footage?

Outside square footage refers to the total exterior surface area of a house's walls. It's calculated by multiplying the perimeter of the house by its height, then subtracting the area of openings such as windows and doors.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{Perimeter} \) — Total distance around the house (ft)
• \( \text{Height} \) — Height of the exterior walls (ft)
• \( \text{Openings} \) — Total area of windows, doors, and other openings (sq ft)

Explanation: This calculation helps determine the amount of exterior surface area that needs materials like siding, paint, or insulation.

3. Importance of Outside Square Footage Calculation

Details: Accurate outside square footage calculation is crucial for construction projects, material estimation, cost calculations, and exterior renovation planning.

4. Using the Calculator

Tips: Enter the perimeter in feet, height in feet, and total openings area in square feet. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure the perimeter of my house?
A: Measure the length of all exterior walls and add them together to get the total perimeter.

Q2: What should be included in openings?
A: Include all windows, doors, garage doors, and any other openings in the exterior walls.

Q3: How accurate should my measurements be?
A: For best results, measure to the nearest inch and convert to decimal feet for calculation.

Q4: Does this include the roof area?
A: No, this calculation only includes the vertical exterior walls. Roof area requires separate calculation.

Q5: Can I use this for multi-story houses?
A: For multi-story houses with different heights, calculate each floor separately and add the results.
