Area & Volume Calculators
The measurement basics: square footage, cubic feet and cubic yards, and pool volume.
- Square Footage CalculatorSquare footage is length × width. Enter an area's two sides in feet and you'll get square feet, plus square yards and square meters.
- Cubic Yard CalculatorBulk materials — concrete, soil, gravel, mulch — are ordered by the cubic yard. Enter the area and how deep you're filling, and this gives the cubic yards (and cubic feet).
- Cubic Feet CalculatorCubic feet measure volume — length × width × height. Enter a box or space's three sides in feet for the cubic feet (and cubic yards).
- Pool Volume CalculatorKnowing your pool's volume in gallons is the starting point for dosing chemicals and sizing a pump or heater. Pick the shape, enter the dimensions and the average depth, and this gives the gallons.
- Pipe Volume CalculatorA pipe is a cylinder, so its volume is the bore area times the length. Enter the inside diameter and length for the gallons it holds — handy for flushing, chlorinating, or filling a line.
- Pond Volume CalculatorEnter your pond's size for the water volume in gallons — for sizing a pump, filter, or treatment — and the flexible liner you'll need to line it.
