This tool is part of these guided projects. Each project provides step-by-step instructions with checklists and all the tools you need in one place.
Plan your yard layout, prepare soil, install paths and beds, seed your lawn, and maintain a thriving landscape.
Plan your garden layout, calculate soil and mulch needs, select plants, and establish a maintenance routine.
Tools you might need next
Calculate topsoil cubic yards for lawn grading, garden beds, and raised areas. Enter coverage area and depth for yards, tons, and bag counts.
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.
Calculate sod pallets and square footage for new lawn installation. Enter yard area to get sod rolls, pallet count, and soil prep topsoil requirements.
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.
