Area Formulas:
Rectangle: Length × Width
Triangle: (Base × Height) / 2
Circle: π × Radius²
Trapezoid: (Base1 + Base2) / 2 × Height

Residential square footage refers to the total area of a living space measured in square feet. It's a crucial metric in real estate, construction, and interior design, helping determine property value, material requirements, and space planning.
Different shapes require different formulas to calculate their area:
Rectangle: \( \text{Area} = \text{Length} \times \text{Width} \)
Triangle: \( \text{Area} = \frac{\text{Base} \times \text{Height}}{2} \)
Circle: \( \text{Area} = \pi \times \text{Radius}^2 \)
Trapezoid: \( \text{Area} = \frac{\text{Base}_1 + \text{Base}_2}{2} \times \text{Height} \)
Details: Precise square footage calculations are essential for property valuation, construction planning, flooring installation, painting estimates, and compliance with building codes.
Tips: Select the shape of your space, enter the required dimensions in feet, and click "Calculate" to get the area in square feet. Measure carefully for accurate results.
Q1: How do I measure irregularly shaped rooms?
A: Break them down into regular shapes (rectangles, triangles), calculate each area separately, then sum them.
Q2: Should I include wall thickness in measurements?
A: For interior space calculations (like flooring), measure wall-to-wall. For exterior measurements, include walls.
Q3: How precise should my measurements be?
A: For most purposes, measuring to the nearest inch (0.08 feet) is sufficient.
Q4: Does this calculator work for metric units?
A: This version uses feet, but you can convert meters to feet (1m ≈ 3.28084ft) if needed.
Q5: How do I calculate square footage for multiple rooms?
A: Calculate each room separately, then add all areas together for the total.
