Wood Hardness

Posted by Aaron Schaalma on Jul 24, 2016

The Janka Hardness Test measures the resistances a sample of wood has to denting and wear. It measures the force required to embed a 11.28mm (.444 inch) steel ball into wood up to half the ball’s diameter. This method leaves an indentation.

A common use of Janka hardness ratings is to determine if a wood species is suitable for flooring.

The harder the wood, the longer it will last under heavy use, however, harder wood also takes longer to sand and refinish.
