Janka wood hardness scale
The Janka rating is a measure of the amount of force required to push a .444" diameter steel ball half way into a piece of wood. In other words, it’s a way to measure a wood’s resistance to denting. So, if you want a hardwood countertop for your kitchen, you need to consider what kind of use and abuse that surface will withstand before you move ahead and decide on species. All woods in this collection are rated to show you their relative resistance to dents and dings. The higher the rating number, the more dent resistant the wood is.
