Wood Countertops Hardness Scale

Selecting the best wood countertops for your kitchen can be a mind boggling decision. At Grothouse, all of our countertops arrive with a comprehensive lifetime warranty so the wood that is visually pleasing to your design should take precedence over all other elements. We are often asked how wood species rank in hardness. The Janka chart has been used as an industry standard for determining the hardness of woods. The Janka hardness test measures the force required to embed a .444-inch steel ball to half its diameter into the respective wood. Keep in mind this hardness test is done only on flat grain or plank style constructions, and the results may vary slightly if you are choosing edge or end grain construction. In addition, the harder woods like Brazilian Cherry do have a tendency to “end check” or develop hairline cracks in the ends of the wood. This is a natural occurrence in select hard species and is not considered a defect. The Janka chart is one of many elements to consider for your countertop aesthetic. Choosing the best wood countertops for your design is a personal decision based on an accumulation of sound information.
