WOOD SPECIES RELATIVE HARDNESS TABLE

Below are listed the relative hardness for numerous wood species used in flooring. These ratings were done using the Janka Hardness Test, which measure the force needed to embed a .444 inch steel ball to half its diameter in a piece of wood. The higher the number the harder the wood. Although this is one of the best methods to measure the ability of wood species to withstand indentations, it should be used as a general guide when comparing various species of wood flooring. The construction and finish also play an important role in the durability and ease of maintenance of any wood floor.
