Janka Scale

When considering a new hardwood floor, it’s important to understand the Janka Scale.

Janka Hardness Rating Scale


The Janka hardness scale is a great tool to use when considering your choice of hardwood flooring species. It is perhaps the most important test, as it measures the hardness of the wood species.

The hardness is expressed numerically as the pounds per square inch of pressure required to sink the ball into the species of hardwood where the higher the number, the harder the hardwood. The Janka hardness test is done on both the side and on the end of the hardwood due to the fact that hardness varies with the grain.

The Janka hardness scale is the industry standard for judging the ability of various hardwood flooring species to withstand denting and wear. It also indicates the effort required to either nail or saw the particular wood and therefore, also helps determine whether the hardwood is suitable for flooring.


One of the most common concerns home owners have about hardwood flooring is how it will hold up to scratches and wear and tear. In particular, they want to know what type of hardwood is going to be best for their individual household of 2.3 kids and 1.8 pets. The Janka Scale is one of the best tools to determine how hard a species of hardwood flooring is, and therefore how it is going to hold up to “Fido” the family dog. The important thing to remember is that all hardwood will scratch to some degree; however certain species like Oak, Hickory, and Maple which are much denser and have a higher Janka Score and are less prone to scratching versus softer hardwoods like Pine, Cherry, and Walnut which will scratch much easier. The higher the Janka Score, the more scratch resistance the hardwood will be.
