Estimate mulch volume in cubic yards and common bag sizes for landscape beds using length, width, and depth.
Rectangular garden beds, tree rings approximated as rectangles, and other simple landscape areas.
A 24 ft × 6 ft bed at 3 in deep shows how a shallow depth can still require multiple cubic yards or bags.
Default example result: 1.47 yd³ with 10% allowance.
The calculator uses the displayed formula, applies your waste allowance, and rounds purchase quantities up. Review the assumptions before ordering and confirm product coverage with your supplier.
Formula used: length × width × (depth ÷ 12) ÷ 27
Use the depth recommended for your plant bed and material. Avoid piling mulch against tree trunks, siding, or structures.
The result shows cubic yards plus common bag equivalents. Confirm the actual bag volume or supplier delivery unit before purchasing.
