How many square feet does a yard of mulch cover at 2 inches?

162 ft² — roughly a 12×14 ft bed. At 3 inches, 108 ft².

How much does 10 yards of mulch cover?

1,620 ft² at 2 inches or 1,080 ft² at 3 inches — a full large-lot refresh. Ten yards ≈ 135 bags equivalent; definitely a bulk delivery.

At 3 in: 50 ft³ = 25 of the 2 ft³ bags (17 of the 3 ft³). At 2 in it's 17 and 12.

ft² × depth (in) ÷ 324 = yards (since 27 ft³ ÷ 12 in = 324). Or skip the mental math with the calculator .

One cubic yard = 27 cubic feet of mulch. Spread at different depths it covers:

Depth	1 yd³ covers	2 yd³	3 yd³	4 yd³	5 yd³
1 in	324 ft²	648 ft²	972 ft²	1,296 ft²	1,620 ft²
2 in	162 ft²	324 ft²	486 ft²	648 ft²	810 ft²
2.5 in	130 ft²	259 ft²	389 ft²	518 ft²	648 ft²
3 in	108 ft²	216 ft²	324 ft²	432 ft²	540 ft²
4 in	81 ft²	162 ft²	243 ft²	324 ft²	405 ft²
6 in	54 ft²	108 ft²	162 ft²	216 ft²	270 ft²

One yard ≈ 13.5 two-cubic-foot bags ≈ nine 3 ft³ bags.
At the standard 3-inch depth, 1 yard covers about 100 ft² — a 10×10 bed, almost exactly.
A standard pickup (6.5 ft bed) holds ~2 yd³ level, 3 heaped; a small trailer (4×6) about 1 yd³.
Need yards from an odd area? area (ft²) × depth (in) ÷ 324 = yards. Example: 500 ft² at 3 in = 4.6 yd³.
