Adjustable shelves provide a flexible surface that can increase the vertical space between levels in a cabinet. Typically, adjustable shelves are created by offering a series of pre-drilled holes that allow the supporting pegs of a shelf to be moved to different positions. Including adjustable shelves in the cabinet’s design allows for greater storage versatility throughout the life of the cabinetry. An adjustable shelf can be a practical addition when combined with an internal shelf that extends half the full depth of the cabinet. Pre-drilled adjustment holes during manufacturing ensure a level adjustment system.

Cabinets are designed and fabricated to follow certain standard dimensions to ensure compatibility between projects. The shelving within a cabinet also follows standard dimensions to ensure predictability in the design and dimensions. For instance, a standard kitchen base cabinet is typically 24 inches deep and 34 1/2 inches tall and comes with one shelf. The shelf is positioned at a height of 17 inches with a thickness of 1/2″. Some cabinet designs include a 12-inch shelf that extends only half the depth of the cabinet, but both types can be adjusted to suit different needs.
