Your own size in the Studio
Pieces come in lengths of 4¾–23⅝ in in steps of 2⅜ in, so in the Studio you set both the length and width of the bed in steps of 2⅜ in. For the exact size, the Studio picks the cheapest combination of pieces and shows the price straight away. You can also draw L and U shapes or terraces on a slope there.
Which height to choose
A lower bed fills faster and is enough for vegetables, a taller one saves your back because you do not have to bend down while working. More layers can be added later too.
