Janka Scale

The Janka scale rates the relative hardness of wood. We have listed some of the most popular choices  and included some more exotic species for your reference and comparison.

 

The higher the number the harder the wood. These ratings were determined using the Janka Hardness Test  which measures the side hardness measure of the  force required to embed a .444 inch steel ball to half its diameter into the wood. This is one of the best measures of the ability of wood species to withstand denting and wear. It is also a good indicator of how hard a species is to saw or nail.

 

This should only be used as a general guide when comparing various species . Depending on where the wood is harvested the results may vary.  A wood's relative hardness is determined with the Janka Rating System, which measures the force required to drive a .444 inch steel ball into the wood until half the diameter of the ball is imbedded in the wood.
