Why You Need to Know About the Janka Hardness Scale

The Janka hardness scale is an industry-standard test that measures the hardness of wood. This test is essential for anyone looking to understand the durability and workability of different wood species.


Here’s why it matters:


  • Measures the force required to embed a .444-inch steel ball into the wood
  • Indicates the wood's ability to withstand denting and wear
  • Helps determine how hard a species is to saw, mill, and nail
