How Much Mulch for 1,000 Square Feet?
1,000 sq ft (about 31.6 × 31.6 ft) covered 3 inches deep takes about 10.19 cubic yards of mulch, or 138 bags of 2 cu ft. That includes 10% extra for settling and uneven ground.
Mulch for 1,000 sq ft by depth
| Depth | Cubic yards | Cubic feet | 2 cu ft bags | Weight |
|---|---|---|---|---|
| 2 in (refresh) | 6.79 | 183.3 | 92 | 4,750 lb |
| 3 in (new bed) | 10.19 | 275 | 138 | 7,130 lb |
| 4 in (weed control) | 13.58 | 366.7 | 184 | 9,510 lb |
Volume = area × depth ÷ 12 = 1,000 × 3 ÷ 12 = 250 cu ft before the 10% extra. One cubic yard covers about 108 sq ft at 3 inches (162 at 2 in, 108 at 3 in, 81 at 4 in).
Gravel for 1,000 sq ft
| Depth | Cubic yards | Tons |
|---|---|---|
| 2 in (light path) | 6.79 | 9.51 |
| 3 in (path, patio base) | 10.19 | 14.26 |
| 4 in (driveway base) | 13.58 | 19.01 |
Gravel is sold by the ton or the yard. These tons assume about 2,800 lb per cubic yard, which varies with stone type and moisture. Sand and topsoil are in the mulch and gravel calculator.
Tips before you order
Spread 2 to 3 inches around established plants and keep mulch a few inches away from trunks and stems. If your bed is not a rectangle, find its area first with the square footage calculator. Bulk delivery is usually cheaper than bags once you need a yard or two; bags make sense for small beds. For a hard surface under gravel, see how much concrete you need for a slab.
