How much mulch for 300 square feet?
Quick Answer
For 300 square feet at the standard 3-inch depth, you need approximately 2.8 cubic yards of mulch, or about 19 bags (2 cu ft bags). At 2 inches deep, you need 1.9 cubic yards or 13 bags. Most landscapers apply 2–3 inches for weed suppression and moisture retention.

How to Calculate It Yourself
- 1
Calculate volume: 300 sq ft × (3" ÷ 12) = 300 × 0.25 = 75 cubic feet.
- 2
Convert to cubic yards: 75 ÷ 27 = 2.78 cubic yards.
- 3
Convert to bags: 75 cu ft ÷ 2 cu ft per bag = 37.5 → 38 bags... wait, that's wrong. Let me redo.
- 4
75 cubic feet ÷ 2 cubic feet per bag = 37.5 bags. Round up to 38.
- 5
Or buy in bulk: order 3 cubic yards for a standard delivery minimum.
Pro Tip
Bulk mulch is typically half the price of bagged mulch per cubic yard. If you need 3+ cubic yards, buy bulk. Most suppliers have a 3 cubic yard minimum for delivery.
