When designing or using cabinet shelves, knowing their weight capacity is crucial for preventing damage or failure. Several factors affect how much weight a shelf can hold, including the material, thickness, span, and method of installation. Here’s a closer look:

Showplace cabinets include 3/4-inch engineered wood or plywood shelves. Remember to distribute weight evenly across the shelf and avoid overloading to prevent warping or damage.

The length of the shelf, or the distance between its supports, is another critical factor. The longer the span, the more prone the shelf will be to sagging under load. Shelves with shorter spans (24-30 inches) can hold more weight than those with longer spans (36 inches or more).
