Calculate pavers needed for patio or walkway. Enter area, paver size, and pattern waste to get paver count, base gravel, and sand bedding quantities.
Calculate gravel cubic yards for driveways, paths, and drainage. Enter area and depth to get tons, cubic yards, and dump truck loads for crushed stone projects.
Estimate retaining wall blocks, base gravel, and drainage for landscape walls. Enter wall length and height for block count and backfill materials.
Multiply bed area by depth converted to feet. Standard decorative mulch depth is 2–3 inches.
Volume (cu ft) = Area (sq ft) × Depth (in) ÷ 12Bulk mulch is delivered by the cubic yard. One cubic yard covers ~162 sq ft at 2″ depth or ~108 sq ft at 3″.
Cubic Yards = Cubic Feet ÷ 27Retail bags typically hold 2 cu ft. Bulk delivery is economical above 2–3 cubic yards.
Bags = ceil(Cubic Feet ÷ 2)Updated: July 2026
500 × 3/12 = 125 cu ft = 4.6 cu yd. Order 5 yards bulk or 63 bags. Refresh annually with 1–2″ top-dress.
320 sq ft total at 3″ = 80 cu ft ≈ 3 cu yd. Extend drip line diameter for mature root protection.
80 × 2/12 = 13.3 cu ft — about 7 bags. Pathways compress under foot traffic — add 10% extra.
Order the right amount of mulch for garden beds, tree rings, and pathways. Enter bed square footage and desired depth in inches to get volume in cubic yards, cubic feet, and standard 2 cu ft bag count.
