Product Calculator

As a rule of thumb for bark coverage, typically 1m3 (cubic metre) will cover 10m2 (metres squared).


Normally bark is laid at least 10cm thick to suppress the growth of weeds and up to 30cm deep in childrens areas. Generally speaking, the more you put down the longer it will last before it needs to be replaced.

Be mindful some compaction will occur with soil and 
compost products. Allow up to 20% for compacting in garden beds etc. 

Odd Shaped Area?

Try this:

  1. Make a rough drawing of your area
  2. Divide that area into sections. Choose dividing lines that will create something close to rectangles. Close is good enough.
  3. Use the calculator above to determine the amount required for each section, and then just add them together.

Or use the reference tables below to help work out the quantities required

Simply measure the width and length of the area you need to cover  eg. 8m x 2m

Then, work out how deep you need the product.


1cm .010   10cm .100
2cm .020   15cm .150
3cm .030   20cm .200
4cm .040   25cm .250
5cm .050   30cm .300
6cm .060   50cm .500


1" Inch thick .025mm   7" Inch thick .175mm
2" Inch thick .050mm   8" Inch thick .200mm
3" Inch thick .075mm   9" Inch thick .225mm
4" Inch thick .100mm   10" Inch thick .250mm
5" Inch thick .125mm   11" Inch thick .275mm
6" Inch thick .150mm   12" Inch thick .300mm


8m x 5m @ 2" thick
8 x 5 x .050 = 2m³ Needed

20m x 6m @ 6" thick
20 x 6 x .150 = 18m³ Needed
