The relative hardness of a wood type is measured using a test called the Janka Hardness Rating. This test measures
the force needed to embed a steel ball (.444 inch in diameter) to half its diameter in the piece of wood being tested,
with the rating measured in pounds of force per square inch. In this rating system, the higher the number the harder
the wood. A rating of 100 points more is a noticeable difference in hardness, less than 100 can be considered
equal.Use the chart below to help as a guide for selection.
