1. What is a Heated Square Footage Calculator?

Definition: This calculator determines the total heated area of a building by summing the area of all individual rooms.

Purpose: It helps homeowners, builders, and appraisers accurately measure the livable space in a property for valuation, heating calculations, and planning purposes.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Length — Room dimension in feet
• Width — Room dimension in feet
• Σ — Sum of all room areas

Explanation: Each room's area is calculated by multiplying its length by width, then all room areas are summed for the total heated square footage.

3. Importance of Heated Square Footage

Details: Heated square footage is crucial for property valuation, HVAC system sizing, energy efficiency calculations, and building code compliance.

4. Using the Calculator

Tips:

• Measure each room's length and width in feet
• Include all heated living spaces (bedrooms, living rooms, kitchens, etc.)
• Exclude unheated areas like garages, porches, and unfinished basements
• Click "Add Another Room" for each additional space

A: Break them into rectangular sections, calculate each separately, then sum the areas.

Q3: Should closets be included?
A: Yes, closets within heated rooms should be included in that room's measurements.

Q4: What about vaulted ceilings?
A: Ceiling height doesn't affect square footage - only the floor area is measured.
