Project calculator
A solid start.
By the cubic yard.
Enter the length, width and depth of a rectangular area to estimate how much material you need.
Measure your project.
Length and width in feet. Depth in inches.
Decimals are welcome, such as 12.5 feet or 3.5 inches.
For an irregular area, divide it into rectangles, calculate each section and add the cubic yards together.
Your material estimate
Three measurements.
One useful number.
Your cubic-yard estimate will appear here once you calculate.
A starting estimate, not an order quantity.
This is the volume of the space you measured. Compaction, waste, uneven ground and material choice may change the quantity to order. No extra allowance is added.
Confirm the final quantity and recommended depth with GBSG before ordering.
Discuss your estimate with GBSG →The math: length (ft) × width (ft) × depth (in) ÷ 324 = cubic yards (CY).
