Calculators
Start with the measured material
Landscape Materials
Gravel Calculator
Calculate cubic yards, US tons, metric tonnes and whole bags for one or several rectangular or circular gravel areas. See what to order when a yard has minimum loads, half-yard increments or delivery charges; use real supplier product details.
Erosion Control Materials
Rip Rap Calculator
Estimate riprap rock for a measured bank or flat bed. Calculate the real slope-face width from horizontal run and rise, then use the designed layer thickness and supplier bulk density.
Drainage Materials
French Drain Calculator
Turn an already planned gravel-filled French drain into a transparent material takeoff. Subtract the pipe’s outside volume from the stone envelope and calculate pipe stock and fabric wrap separately.
Landscape Materials
Landscape Fabric Calculator
Plan fabric strip layout and perimeter or seam fasteners for beds and paths.
Landscape Materials
Paver Base Calculator
Turn a patio footprint into separate ready-to-order base gravel and bedding sand quantities.
