Soil for a 3 × 10 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 |

Measure inside the walls
The table uses the full 3 × 10 ft. If that is the outside size of a wooden bed built from boards 1½ inches thick, the growing space inside is 33 × 117 inches. At 12 inches deep that holds 26.81 cubic feet, 11% 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.
