How It Works

This calculator finds the total volume of your garden bed (length × width × depth). If you provide the size of a bag of mulch, it will calculate how many bags are needed to fill that volume. A common mulch depth is 3-4 inches (7-10 cm).

Understanding Mulch Calculations

Mulch is sold by volume, typically in cubic yards (bulk) or cubic feet (bags). It's one of the easiest ways to improve your garden's appearance and health, retaining moisture and suppressing weeds.

The 3-Inch Rule

For most landscape beds, a depth of 3 inches is ideal. Less than 2 inches won't stop weeds; more than 4 inches can suffocate plant roots.

1 Cubic Yard = 27 Cubic Feet
Coverage at 3" depth ≈ 100 Square Feet per Cubic Yard

Bags vs. Bulk Delivery

Bagged Mulch

  • Size: Usually 2 cu. ft. per bag
  • Convenience: Easy to carry to backyards
  • Cost: More expensive per yard
  • Math: 13.5 bags = 1 Cubic Yard

Bulk Mulch

  • Size: Sold by the scoop (cubic yard)
  • Convenience: Delivered to driveway
  • Cost: Much cheaper for large projects
  • Math: Best for areas > 500 sq ft
