Soil for a 3 × 4 ft bed at each depth
Whole bags are rounded up. The bed’s wall height is not the soil depth: measure the depth you plan to fill.
| Soil depth | Cubic feet | Cubic yards | Bags of ¾ ft³ | Bags of 1 ft³ | Bags of 1.5 ft³ | Bags of 2 ft³ | Bags of 3 ft³ |
|---|---|---|---|---|---|---|---|
| 6 in | 6 | 0.22 | 8 | 6 | 4 | 3 | 2 |
| 8 in | 8 | 0.3 | 11 | 8 | 6 | 4 | 3 |
| 10 in | 10 | 0.37 | 14 | 10 | 7 | 5 | 4 |
| 12 in | 12 | 0.44 | 16 | 12 | 8 | 6 | 4 |
| 18 in | 18 | 0.67 | 24 | 18 | 12 | 9 | 6 |
| 24 in | 24 | 0.89 | 32 | 24 | 16 | 12 | 8 |
Measure inside the walls
The table uses the full 3 × 4 ft. If that is the outside size of a wooden bed built from boards 1½ inches thick, the growing space inside is 33 × 45 inches. At 12 inches deep that holds 10.31 cubic feet, 14% less than the table. Metal and composite walls are thinner, but corner posts and braces still take space, so measure between the inner walls before you order.
Beds sold at 3 × 4 ft
These are the beds we list in this size. A maker’s stated capacity often differs from the table because the inside is smaller than the advertised size or the maker assumes a different fill depth.
