The width of the cabinet opening largely determines what can fit inside. Measure your cabinet width making sure to measure the opening, and not the inside width of the cabinet. Most cabinets come in widths of 12", 15", 18", 21", 24", 30", 33", 36", or 48" wide.
Check the “Minimum Cabinet Opening” requirements on the Simply Put organizer you are considering. Your cabinet opening should be at least this wide. For example, if your cabinet is 12 inches wide, choose a Simply Put Pullout with Minimum Cabinet Opening requirement of 11 inches. A 24-inch wide cabinet can accommodate a Simply Put organizer that is 20 inches wide or less.
