Hardwood Flooring Species Hardness

Relative hardness of selected wood flooring species. (Ranked by janka hardness rating)

The Janka (or side) 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. By the same token, it also is a good indicator of how hard or easy a species is to saw or nail. Northern red oak, for example, has a Janka hardness rating of 1290. Brazilian Cherry, with a rating of 2820, is more than twice as hard. If you’re accustomed to working with red oak and decide to tackle a job with brazilian cherry hardwood flooring, you can expect it to be much harder to cut and nail down.

While Janka values give a general sense of hardness, many other factors also contribute to a wood floor’s durability, including the type of cut (i.e. plainsawn, quartersawn), denseness of cell structure, and finish used.
