The soil calculator below will help you determine how much soil or potting mix you need regardless of growing in pots or raised beds.
The soil calculator is a useful tool to help you work out how much soil or potting mix you need. No matter the size of your gardening project, when getting started on an edible garden, you’ll be asking how much soil do I need for my raised garden bed or container.
I’ve taken the guesswork out by providing two soil calculators, one for square and rectangular shapes, the other for a round container. The calculators below will help you determine how much soil or potting mix you need regardless of whether you’re growing in pots, raised beds, long troughs or even buckets.
I found it most useful when planning the raised garden bed and it helped me set a budget for how much I was going to spend on that project.
Soil Calculator for a Rectangular or Square Container
To calculate the volume of soil in Litres you need for a rectangular or square container (or raised garden bed), enter the length and width in metres, the depth in centimetres and the calculator will work it out for you.
Soil Calculator for a Round Container
To calculate the volume of soil in Litres you need for a round container, enter the diameter and depth in centimetres.
