Mulch Calculator
Work out how much mulch you need for a garden bed or landscaped area.
How the mulch estimate works
- Volume in cubic feet is length times width times depth in feet (depth in inches divided by 12).
- The waste percentage is added on top to cover uneven ground and spillage.
- One cubic yard equals 27 cubic feet.
- The bag count is the total cubic feet divided by the bag size, rounded up.
Bags or bulk?
Bags are easy to carry and good for small beds. If you need more than about 2 cubic yards, buying in bulk from a landscape supplier is usually cheaper per cubic foot. Ask whether they deliver.
