- 25 bags of 2 cu ft mulch — at 3 inches deep
- 17 bags of 3 cu ft mulch — at 3 inches deep

Bags Needed for 200 Square Feet by Depth
The depth you choose changes the bag count significantly.
Three inches is the standard for most garden beds and landscaping.
| Depth | Cubic Feet | 2 Cu Ft Bags | 3 Cu Ft Bags |
|---|---|---|---|
| 1 inch | 16.7 cu ft | 9 bags | 6 bags |
| 2 inches | 33.3 cu ft | 17 bags | 12 bags |
| 3 inches ← standard | 50.0 cu ft | 25 bags | 17 bags |
| 4 inches | 66.7 cu ft | 34 bags | 23 bags |
| 6 inches | 100.0 cu ft | 50 bags | 34 bags |
The Formula
Cubic feet = length × width × (depth in inches ÷ 12)
Bags needed = cubic feet ÷ bag size — round up
Example — 200 sq ft at 3 inches, 2 cu ft bags
- Volume = 200 × (3 ÷ 12) = 200 × 0.25 = 50 cu ft
- Bags = 50 ÷ 2 = 25 bags
- In cubic yards: 50 ÷ 27 = 1.85 cubic yards

Should You Buy Bags or Order Bulk Mulch?
For 200 sq ft at 3 inches you need 1.85 cubic yards —
right on the boundary between bags and bulk.
buying bags. In many areas bulk mulch at this volume costs
roughly the same as bags and saves carrying 25 heavy bags.
| Volume | Recommendation | Reason |
|---|---|---|
| Under 1 cubic yard | Buy bags | Too small for bulk delivery to be cost-effective |
| 1–2 cubic yards | Compare both | Get a bulk quote — often similar in price to bags |
| Over 2 cubic yards | Order bulk | Bulk is cheaper per yard and saves significant labour |
