How do I calculate how much mulch I need?

Multiply area by depth to get volume. Convert depth to feet (inches ÷ 12), then volume (ft³) ÷ 27 gives cubic yards. The calculator does this for you and provides bag/bulk options.

How deep should mulch be?

Use 2–4 inches for garden beds to suppress weeds and retain moisture. For playgrounds, use 6–12 inches for safety cushioning depending on equipment height and standards.

Mulch Tips

Keep mulch 2–3 inches away from trunks and stems to prevent rot.
Use 2–4 inches for beds; 6–12 inches for playground safety surfacing.
Consider bulk delivery for large projects; bags are convenient for small jobs.
Typical bag sizes: 1.5, 2.0, or 3.0 ft³. Adjust above if needed.
