TL;DR
Shelf bracket spacing is the on-center distance between the supports that carry a shelf, set by the shelf material and the load it must hold without sagging. Particleboard and MDF want brackets every 16 to 24 inches, solid lumber spans 24 to 32, and heavy storage such as books or paint pushes everything toward the tighter figure with brackets lagged into studs.
What it means
Shelf bracket spacing is the on-center distance between the supports that carry a shelf, set by the shelf material and the load it must hold without sagging. Particleboard and MDF want brackets every 16 to 24 inches, solid lumber spans 24 to 32, and heavy storage such as books or paint pushes everything toward the tighter figure with brackets lagged into studs. The deflection rule of thumb is that visible sag means the span is too long, not that the shelf is overloaded.
