Measurement & Cost Calculators

Square footage, cubic yards, board feet and cost tools.

Every material estimate starts with a measurement in the right unit: square feet for surfaces, cubic yards for bulk, board feet for lumber, linear feet for trim. The tools here handle those conversions and the two questions that follow every takeoff: how much waste to add, and roughly what the project will cost.

Use them before the material-specific calculators. Measure once with the square footage or cubic yard tool, then carry the number into the flooring, concrete or mulch calculator that turns it into an order.

All measurement & cost calculators

Square Footage CalculatorCalculate the square footage of a room, floor, wall or lot. Handles rectangles, circles, triangles and L-shaped rooms and converts to square yards and acres.Cubic Yard CalculatorConvert length, width and depth into cubic yards and cubic feet for concrete, gravel, soil or mulch, and estimate the weight in tons for common materials.Cubic Feet CalculatorCalculate the cubic feet of a box, appliance or room from its length, width and height in inches or feet, with the volume in cubic inches, cubic yards and gallons.Excavation CalculatorCalculate the bank cubic yards to dig, the loose volume after swell, the weight in tons, how many truckloads it takes to haul away, and the haul-off cost.Renovation Cost CalculatorEstimate a renovation budget range from square footage, project type, finish quality and region, with a midpoint, contingency reserve and cost per square foot.Material Waste CalculatorAdd the right waste factor to any measured quantity of flooring, tile, drywall, paint, roofing, concrete, lumber, brick or siding to find how much to actually buy.Linear Feet CalculatorConvert square feet to linear feet of boards from the board width, or find the linear feet around a room, then add waste and count the pieces of stock to buy.

Measurement & Cost questions

How do I convert square feet to cubic yards?

Multiply the area by the depth in feet, then divide by 27. 100 square feet at 4 inches is 100 x 0.333 / 27 = 1.23 cubic yards.

How many square feet are in a square yard and an acre?

9 square feet in a square yard and 43,560 square feet in an acre.

How much waste should I add to a material estimate?

10% is the usual default for flooring, drywall, paint, lumber and simple roofs; 15% for diagonal layouts, hip roofs and large-format tile; 5% for brick and block.
