The Janka Hardness Scale is used to measure the force necessary to embed half the diameter of a steel, .444 inch ball into the wood. Woods scoring a high rating on the janka scale are considered harder. Because of this the Janka Scale is a good indication of how resistant each wood species is to denting and wear and a useful way to see how hard the wood will be to saw or nail. The Janka Scale is a tried and tested method used worldwide.
* represents one species.
