Though many people don’t enjoy stepping onto a scale, they sure as love reading or interpreting one…. the Janka Hardness Rating is how the relative hardness of a wood species is measured. 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. So with this rating system, the higher the number the harder the wood. Today, most people are on the hunt for a really high Janka Ranking; but they fail to realize that every wood on the market can be Scratched. Most flooring customers think that a high Janka Rating will prevent scratches on their new floor, but that is really far from the truth. The harder the wood (High Janka Rating) the harder it will be for that particular wood floor to get “dented”………..Denting a floor and Scratching a floor are two very different things.
Keep In Mind: What is harder? Metal or Wood? Correct, Metal is. But can I come up to a car and scratch it? Ohh, Yes I can!
So even if you buy the hardest wood in the world and you decide to drag some furniture w/ exposed metal legs across the room; I can promise that with will all of the HIGH Janka Numbers that your floor may possess you will be very disappointed as to how your floor may look after the fact.
So, the answer to the question; Do Janka Ratings Really Matter? They really don’t after about 1,300 points (the approx. hardness of Oak).
