Formula

yards = area × depth(in) ÷ 324 · bags = yards × 27 ÷ bag size

Example

200 sq ft at 3 inches ≈ 1.85 yd³ ≈ 25 bags of 2 cu ft.

Why depth matters

Two inches refreshes appearance; three suppresses weeds effectively; beyond four you risk smothering roots and trapping moisture against stems. Keep mulch pulled back from tree trunks.
