Janka Hardwood Scale
The Janka Hardness Scale determines the hardness of a particular type of wood over another. The scale was invented in 1906 by Gabriel Janka, an Austrian wood researcher, and standardized in 1927 by the American Society for Testing and Materials (ASTM).
The Janka Hardness Scale Some Important Facts You Should Know
Janka hardness testing The actual number listed in the wood profile is the amount of pounds-force (lb f) or newtons (N) required to imbed a .444โณ (11.28 mm) diameter steel ball into the wood to half the ball's diameter. This number is given for wood that has been dried to a 12% moisture content, unless otherwise noted.

The Janka hardness scale is a measure of the hardness of a given species of wood and its level of durability. It is named after its inventor, an Austrian wood researcher named Gabriel Janka which was standardized in 1922. The Janka hardness test is a variation or adaptation of the Brinell hardness test.

What is Janka Hardness Rating? Pinnacle Floors
Hardness, or "JANKA VALUE" is measured with a test of resistance of a sample of wood to denting and wear. It measures the force required to embed an 11.28mm (.444 in) steel ball into wood to half the ball's diameter leaving an indentation in the wood. JANKA VALUES SOFTER WOOD HARDER WOOD SPECIES 0
How hard is hardwood? The Janka scale
The Janka hardness scale measures the force that's required to embed a steel ball halfway through a sample of wood. The ball is 0.444 inches in diameter and fired with increasing force. The pounds of force (or newtons if you're using the metric system) needed to push the ball to the center is the Janka value you end up with.
How the Janka Hardness Scale Can Help You Choose Your Flooring ACo
As such, it is recommended to use the Janka scale in combination with other tests and evaluations when making decisions about the suitability of wood for different applications. Overall, the Janka hardness scale is a valuable tool for determining the hardness and durability of various types of wood and is widely used by lumber suppliers.
A Homeowner's Guide to Hardwood Floor Hardness Flooring Products
The industry standard method for determining the hardness of wood products is called the Janka hardness test. Janka hardness of a given wood species is defined by a resistance to indentation test as measured by the load (pounds of pressure) required to embed a 11.28mm or 0.444" diameter ball to one-half its diameter into the wood.

Janka Hardness Ratings of Wood Species It is important to remember that the testing process used in the Janka scale is an impact test, not a test of scratching, scuffing, or any other wear and tear that flooring experiences. To learn the basic hardness of different common woods used in flooring, check the chart below.
Janka Hardness Scale
The Janka scale is a helpful tool for comparing various types of hardwood floors. This page will comprehensively break down how this wood hardness scale works and what makes bamboo & eucalyptus floors so sturdy. Strand woven bamboo flooring, on average, has Janka ratings upwards of 3,800, which is much higher than traditional wood flooring.
Janka Hardness Scale for Woods
Janka Hardness Scale is simply a scale that ranks species of wood, based on their hardness. The hardness is determined by testing the amount of force necessary to implant a steel ball into a plank of wood. The result is that the hardness, resistance, and durability of the wood are tested using this method. The harder the wood, the more force is.
Janka Hardness Scale Measuring wood hardness
The Janka Test is a measure of the hardness of wood. The Janka Test was developed as a variation of the Brinell hardness test. The test measures the force required to push a steel ball with a diameter of 11.28 millimeters (0.444 inches) into the wood to a depth of half the ball's diameter.
Janka Hardness Scale Learn How Hard Each Wood Species Is
Wood species vary in many ways, but a key factor in finishing wood is the hardness of the wood. A common measurement for wood hardness is the Janka scale. The Janka scale measures the resistance of a sample of wood to denting and wear and is typically expressed in lbf (pounds-force) or N (Newtons). The US typically will use lbf.
Understanding the Janka Rating Scale
The Janka scale, simply put, records the density of wood by testing its resistance to denting. The test measures the force required to embed a .444-inch (11.28mm) diameter steel ball halfway into a piece of wood. That force is recorded in pounds-force (lbf) in the U.S. or in kilograms-force (kgf) or newtons (N) in other parts of the world.
