How much mulch should I buy?

As a general rule of thumb, one cubic yard of bark mulch will cover an area measuring about 100 square feet. Most landscape professionals recommend a depth of about 3-inches thick. If you’re adding a layer of top dressing to an area that was previously mulched, you may wish to use a little less.

How to Measure

To calculate the amount of mulch you’ll need, measure the length and width of the area you wish to cover. Remember if you pace it out or use meters, you’ll need to convert your calculations to feet.

Multiply length x width to determine the number of square feet to be covered.

For example, let’s say you wish to mulch an area 100 feet long and 10 feet wide. Multiplying the length (100 ft.) X width (10 ft), we come up with an area measuring 1,000 square feet. Divide total square feet (1,000) by 100 to determine the number of cubic yards of bark mulch you’ll need to order.

The following chart can be used to help you determine the number of yards of bark mulch you’ll need to order.
