Driveway Square Foot
Calculator — Paving Area Tool

Measure the driveway length and width in feet, then multiply them together. A driveway 40 feet long and 12 feet wide is 480 square feet. For curved or tapered driveways, use the trapezoid or circle calculator option.

A typical single-car driveway is 200 to 480 square feet (10-12 ft wide × 20-40 ft long). A double-wide driveway is 400 to 960 square feet (20-24 ft wide × 20-40 ft long).

Concrete driveway installation costs $4 to $8 per square foot on average, including materials and labor. Stamped or colored concrete costs $8 to $18 per square foot. Enter your price per square foot in the calculator to estimate total cost.

For a circular turnaround, use the circle calculator with the diameter. For a curved section, approximate the shape as a trapezoid by measuring the two parallel widths and the length. For complex curves, split into sections and add the areas.

A standard residential concrete driveway should be 4 inches thick. For heavy vehicles or RVs, increase to 5-6 inches. The thickness affects the volume of concrete needed but not the square footage calculation.

Calculate the driveway area in square feet using length × width. Asphalt costs $3 to $6 per square foot installed. A 480 sq ft driveway would cost $1,440 to $2,880 for asphalt paving.
