Janka Hardness Chart
The Janka hardness chart shows which wood species are suitable for flooring based on your lifestyle. The Janka hardness scale measures the resistance to denting or crushing of the cellular structure. This is done with a steel ball and measures the force required to embed half of its diameter into a sample of the species, measured in pounds force (lbf). The higher the score, the harder the wood species.
Janka ratings are worth considering for both engineered or solid hardwood flooring. Hardness of a species will also be influenced by how the wood is cut or the direction of the grain. An interesting fact is that a 120 lb. woman in high heels creates 2,800 psi. This puts into perspective how and why some floors dent more easily than others.
