How to select the right garden bed for your yard 1.) Select a style, "cabin" or "plank"Currently we offer two different styles, the "cabin" which is three layers of 2x4s, and the "plank" which is a single board, forming the side walls. 2.) Select a size, you may want to measure the space you have allotted for your raised beds. Our standard width is 32 inches (nearly 3 feet) and 48 inches (4 ft.) wide, while the standard length is either 48 inches (4 ft.) or 96 inches (8 ft.). Custom sizes can be built but require a 10% surcharge from the next closest size. 3. Select accessories such as copper post caps, wooden or the "Hampton" post caps, or a "seat shelf" which caps the sidewall with a 2x4 so that sitting on the edge of the bed and gardening are possible. Finally, there is the "basic" unit with no post caps nor "seat shelves". 4. Determine if you want a trellis or not. They are great for climbing vegetables such as beans, peas and cucumbers, or can be used for decorative flowers such as trumpet flower or morning glory. Trellis are 5 feet tall by nearly 4 feet wide and are attached to the side walls and corner posts. Trellises can also run the length of a full 8 foot bed.
