Hardness Chart

Relative hardness of wood flooring species

Below are listed the relative hardness for numerous wood species used in flooring. These ratings were done using the Janka Hardness Test. The Janka hardness test measures the force required to embed a .444 inch steel ball to half its diameter in wood. It is one of the best measures of the ability of a wood species to withstand denting and wear. The higher the number, the harder the wood is.This should be used as a general guide when comparing various species of wood flooring. Ratings will vary depending on various environmental factors.
