Free Wood Hardness List Janka Chart Download

Free Downloadable Janka Hardness Chart

| Shane Dennehey

The Janka Hardness Score helps woodworkers find out how dense a particular species of wood is. Woods with a high score are more resistant to dents, dings, and other wear marks. They are also more challenging to work with and will dull your blades faster than low scoring woods.

The score is determined by measuring the force required to embed a 0.444-inch steel ball exactly halfway into a piece of wood. The measured power, in pounds, is the score. Harder woods get higher numbers.

This free printable chart arranges the scores of popular woods by region with a bar chart so you can easily compare the Janka scores of your favorite woods.
