What is a Janka Rating?

"It is one of the best measures of the ability of a wood species to withstand denting and wear. It is also a good indicator of how hard a species is to saw or nail.

The hardness of wood usually varies with the direction of the wood grain.

A common use of Janka hardness ratings is to determine whether a species is suitable for use as flooring."
