Total Area = Sum of Room Areas
| From: | To: |
House square footage calculation determines the total floor area of a property by summing the areas of individual rooms. This measurement is essential for real estate valuation, renovation planning, and space utilization assessment.
The calculator uses the formula:
Where:
Explanation: The calculator multiplies the length and width of each room to get its area, then sums all room areas to calculate the total square footage.
Details: Precise square footage calculations are crucial for property valuation, construction planning, interior design, and compliance with building codes and regulations.
Tips: First enter the number of rooms, then provide length and width measurements for each room in feet. Measure each room at its longest and widest points, excluding non-living spaces like closets and wall thickness.
Q1: Should I include closets and storage areas?
A: Typically, only finished living spaces are included in square footage calculations. Closets are usually included, but unfinished storage areas are not.
Q2: How do I measure irregularly shaped rooms?
A: Divide irregular rooms into rectangular sections, calculate each section's area separately, then sum them together.
Q3: Are staircases counted in square footage?
A: Staircases are typically counted once, on the floor where they originate, in most standard calculation methods.
Q4: Should I measure from inside or outside walls?
A: For interior space calculations, measure from the interior surface of walls to get the usable living space.
Q5: How accurate are these calculations for real estate purposes?
A: While this calculator provides a good estimate, official real estate measurements should be done by certified appraisers following local standards.
