Measure inside the walls

The table uses the full 2 × 6 ft. If that is the outside size of a wooden bed built from boards 1½ inches thick, the growing space inside is 21 × 69 inches. At 12 inches deep that holds 10.06 cubic feet, 16% 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 2 × 6 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.
