DIY Calculators OnlineHow it's calculated
cubic yards = length × width × depth (in) ÷ 12 ÷ 27
One cubic yard is 27 cubic feet, or 13 1/2 bags of 2 cu ft. Above about 2 yards, bulk delivery is usually cheaper than bags.
How deep?
| Use | Depth |
|---|---|
| Refreshing existing mulch | 1–2" |
| New beds, weed control | 2–3" |
| Paths and play areas | 3–4" |
Keep mulch a few inches back from tree trunks and plant stems. Piling it against the bark holds moisture there and invites rot.
