Soil for a 4 × 8 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.

Measure inside the walls
The table uses the full 4 × 8 ft. If that is the outside size of a wooden bed built from boards 1½ inches thick, the growing space inside is 45 × 93 inches. At 12 inches deep that holds 29.06 cubic feet, 9% 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.
Building it from 2 × 6 boards? The 4 × 8 ft bed plan has the cut list and the steps for this outside size: filled 10 inches deep, it takes 16 bags.
