How Much Soil for a Raised Bed?
The volume formula is length × width × depth, all in feet (convert inches of depth to feet by dividing by 12). Multiply by how many matching beds you plan to fill.
This preset uses a 3 ft × 6 ft bed at 12 inches deep — a size that fits many kit frames. Download a PDF with assumptions and purchase lines.
