Rectangle
Length × Width
12 ft × 10 ft = 120 sq ft
Circle
π × r²
π × 5² = 78.54 sq ft
Triangle
½ × Base × Height
½ × 10 × 8 = 40 sq ft
Trapezoid
½ × (A + B) × Height
½ × (8+12) × 6 = 60 sq ft
L-Shape
(L1 × W1) + (L2 × W2)
(10×8) + (6×4) = 104 sq ft
Ellipse
π × a × b
π × 6 × 4 = 75.40 sq ft
For a rectangular room, multiply the length by the width in feet. For example, a 12x14 foot room is 168 square feet. For irregular shapes, break the area into simpler shapes (rectangles, triangles), calculate each, and add them together.
One acre equals 43,560 square feet. A standard American football field (not including end zones) is about 48,000 square feet or 1.1 acres. For reference, a quarter-acre lot is about 10,890 square feet.
Multiply square feet by 0.0929 to get square meters. For example, 1,000 sq ft equals approximately 92.9 square meters. This calculator automatically shows conversions to all common area units.
A standard bedroom is 10x12 feet (120 sq ft), a master bedroom is 14x16 feet (224 sq ft), a living room is 12x18 feet (216 sq ft), and a single-car garage is 12x20 feet (240 sq ft). Room sizes vary by region and home style.
