Understanding Wood Hardness

Wood hardness is primarily measured by the Janka hardness test, which assesses the resistance of wood to denting and wear. This test involves embedding a steel ball into the wood and measuring the force required to do so. The results are expressed in pounds-force (lbf). The higher the Janka rating, the harder the wood.

The Janka hardness ratings for various woods can provide a clear comparison of their durability. Here are some key points regarding wood hardness:

  • Durability: Hardwoods tend to be more durable and resistant to wear.
  • Workability: Harder woods can be more challenging to work with due to their density.
  • Applications: Hardwoods are typically used for furniture, flooring, and cabinetry due to their strength and longevity.
