Paver base calculator

Plan the base under a patio or walkway. Returns crushed-stone base plus 1" leveling sand.

Short answer: Base tons = (L × W × baseDepth/12) ÷ 27 × 1.35. Sand tons = same with sand depth × 1.35. 12 × 10 ft, 4" base + 1" sand = 2.0 t crushed + 0.5 t sand. Enter your measurements above and the paver base calculator returns the quantity, unit conversions and an estimated cost instantly, in imperial or metric — no sign-up needed.
