Make all stall widths in multiples of 42”, 44”, 45”, 46”, 48”, 51” or 54”. If your contractor lays out the stalls such that your widths are anything other than exact multiples you will have to plan for extra seams. If you make the end stall anything but the full dimension, you will need to end the run one (1) stall short and place a small bed in the end stall.
