Relative hardness of wood flooring species

Below are listed the relative hardness for numerous wood species used in flooring. These ratings were done using the Janka Hardness Test. The Janka hardness test measures the force required to embed a .444 inch steel ball to half its diameter in wood. It is one of the best measures of the ability of a wood species to withstand denting and wear. The higher the number, the harder the wood is.This should be used as a general guide when comparing various species of wood flooring. Ratings will vary depending on various environmental factors.

Understanding the Janka Hardness Scale is essential for selecting the right hardwood flooring for your home or office. This scale not only helps in assessing the durability and resistance to wear and tear of different wood species but also assists in choosing the right kind of wood for specific applications. For instance, softer woods might be suitable for areas with less foot traffic, whereas harder woods are ideal for high-traffic areas or commercial spaces. Moreover, the Janka rating can influence maintenance requirements and the long-term appearance of the flooring. By considering these factors, you can make a choice that balances aesthetic appeal with practical functionality, ensuring a beautiful, long-lasting hardwood floor.
