Use this handy calculator to work out the number of BlocX that you need for you project.

Just enter the Length, Width and Height and let the calculator do the hard work.

When you receive your BlocX you will also get detailed layer by layer instructions. Simple and fun!

If you would like to order multiple boxes just add the box quantities to your cart then come back and add another.

We recommend 2 (25cm) or 3 (35cm) blocx high for standard raised vegetable beds, this gives you plenty height for most vegetables to grow.

It is possible to build beds any height that suits you up to 1 meter high. Making weeding, sowing and planting less of a chore.

This calculator is based on our standard construction method, which we recommend, for strength. If you would like us to get closer to specific sizes we will have to use a combination of smaller BlocX, this will mean the structure will have stightly less rigidilty as a standard size design. If you want us to look at specific sizes for you please get in touch via email or phone and we can put a design together to suit your specific needs.
