Your measurements should be for the INTERIOR L x W floor dimensions of your garden - not the outside walls. SIP's are 12"x12". Therefore, full foot interior measurements are easiest to work with. For example, a 2' x 4' interior floor measurement is exactly 2 SIPs wide and 4 SIPs long.
If you have a garden that is not in full foot measurements, or a shape that is not square/rectangular, the SIPs can be trimmed and/or shaped for almost any garden. Contact us for details and advice!
