Use this mulch calculator to estimate the amount of mulch or soil needed to cover an area at a specific depth.

To know how many bags of mulch in a yard are required, you can use the formula:

**Cubic Yard of Mulch =Square Footage x Desired Depth / 324**

**Mulch Volume (in cubic yards) = [(Length (ft) × Width (ft) × Depth (ft))/27**

One cubic yard of mulch covers around an area of 324 square feet of 1 inch of depth.

It is better to add 5-10% extra mulch for the miscalcations or wastage.

For the irregular shape, break down the area into regular shapes to calculate how many bags of mulch in a cubic yard are required precisely.

**Four inches:**Maximizes Protection

**Three inches:**A Happy Medium

Too much mulch can maintain enough moisture to invite decay near your plants.

Mulch Examples

Let's say a garden bed is 10 feet long and 5 feet wide, and apply mulch at a depth of 3 inches. Then calculate how many cubic feet in a yard of mulch is required.

**Total Mulch Needed (in cubic yards) = (Length (in feet) × Width (in feet) × Depth (in inches)) / 324**

Our mulch calculator utilizes the above formula that also helps you estimate mulch volume if calculated manually.

Total Mulch Needed = (10 ft × 5 ft × 3 in) / 27

Cubic yard of mulch ≈ 0.46cubic yards

Mulch Needed= 12.5 cubic feet (cu ft)

Mulch Needed = 0.35 cubic meters (m3)

Mulch Needed = 353.95 liters

Garden size = 50 sq. ft

No of bales needed = 1.28 sq. ft

Desired depth | Sq.ft coverage | Approx coverage |
---|---|---|

1 inch | 324 sq. ft | 18' × 18' |

2 inches | 162 sq. ft | 13' × 13' |

3 inches | 108 sq. ft | 11' × 10' |

4 inches | 81 sq. ft | 9' × 9' |
