If you’re planning a new raised bed garden or refreshing an existing one, one of the biggest questions I get is always the same:

“How much soil do I actually need to buy?”

Good news: You no longer have to guess.

I created this simple Raised Bed Soil Calculator to help you determine exactly how much soil, compost, or raised-bed mix to purchase before you start filling your beds.

HOW TO USE THE RAISED BED SOIL CALCULATOR

Using the tool is easy:

Measure your raised bed
– Length 
– Width 
– Depth

Choose your units
(Feet + inches are most common for raised beds.)

Select your soil bag size if your total yards 1 yard or less
I often find it is more expensive to have a less than a yard of soil delivered and shovel than to simply buy bags of soil. Many stores carry 1, 1.5, or 2 cubic-foot bags and the calculator will help you know how many bags of raised bed soil you should purchase.

Enter the number of identical beds
If you’re building several beds, this saves tons of time.

Click Calculate to see your results instantly.

Then, just copy the summary and take it with you when you shop for soil.
