Computation Accuracy
Precision is limited by measurement fidelity. For complex architectural perimeters, subdivide into primary geometric primitives and aggregate results.
A professional manual for architectural measurement, real estate surfacing, and material quantification.
A square footage calculator answers the question that every homeowner, renter, real estate agent, and contractor asks: "Given the dimensions of a room or building, how many square feet of floor area does it contain – and how much paint, flooring, or tile do I need?"
Square footage is the standard measure of area for real estate, construction, and home improvement. It’s the total floor area inside a building, usually measured in square feet (ft²).
"For real estate listings, square footage typically includes only finished, livable space (heated and cooled). Garages, unfinished basements, and porches are often excluded."
| Primitive Shape | Logic Formula | Example Resolve |
|---|---|---|
| Rectangle / Square | length × width | 12 ft × 10 ft = 120 ft² |
| Triangle | (base × height) / 2 | base 10, height 6 = 30 ft² |
| Circle | π × r² | radius 5 ≈ 78.5 ft² |
Measure the primary length and width of the room in feet and inches.
Convert inches to decimal feet (divide by 12). 6 inches = 0.5 ft.
Multiply L × W for simple rooms. For L-shapes, divide into rectangles.
When ordering materials, always add a waste percentage to account for seaming, breakage, and pattern matching.

Typical Exclusions
The 12.6 Trap
Confusion between decimal feet and inches. 12'6" is 12.5 ft, not 12.6 ft.
Net vs Gross Load
Floor area uses interior dimensions. Measuring exterior walls overestimates space.
