Why quantities go wrong
Landscaping materials are sold in units nobody measures their yard in. You measure in feet and inches; suppliers sell in cubic yards, tons, and pallets. Every calculator on this site does that conversion instantly, uses the standard depths and densities suppliers quote, and rounds up — because running out of mulch on a Saturday afternoon means a second trip, but a quarter-yard extra just tops up next year's beds.
Estimates, not gospel
These calculators use industry-standard assumptions: 2 cu ft mulch bags, 10 sq ft sod rolls, typical stone densities, a 4-inch paver base. Materials vary by region and supplier, so confirm final quantities when you order — and when in doubt, round up.
