Wood Hardness Chart

Choosing floors with the wood hardness chart

Durability is a prime consideration when selecting the wood for your new floors. There’s a wide range of woods commonly used for flooring and lots of variety in the density of each species. The denser the wood, the more resistant to scratches, dents and dings the floor will be.

To get a read on the density and durability of Oak vs. Maple or Pine vs. Oak, for example, you can simply consult the Janka wood hardness chart. The Janka test measures wood density by determining how much force is required to push a small steel ball halfway into a plank. The test results are listed on the Janka wood hardness chart as pounds of force, or pounds-force (lbf). An extremely dense wood like Ebony, for example, requires 3,220 lbf to embed the steel ball. In comparison, an extremely softwood like balsa requires only 70 lbf.

With the Janka wood hardness chart, it’s easy to compare the relative density of a Red Oak floor (1290 lbf) with the much harder Hickory (1820 lbf) or the much softer Eastern White Pine (380 lbf).

At Carlisle Wide Plank Floors, we offer hardwood and pine floors made with species that span a wide range of values on the Janka wood hardness chart. Our wide plank specialists can walk you through the benefits of using a highly dense wood like Maple or a much softer wood like Cherry.

Common types of flooring on the Janka wood hardness chart

While the Janka wood hardness chart provides values for many types of wood, only a limited number of species are commonly available as hardwood or Pine floors. At Carlisle, we offer a variety of woods that range from extremely dense to fairly soft, enabling our customers to choose the perfect floor for their home.

  • Hickory (1820), the hardest of commonly available hardwoods, boasts a tensile strength that rivals steel. Hickory features very interesting grain patterns and a color palette that runs from lighter blonde in the sapwood to rich cocoa brown and beige in the heartwood.
  • Brown Maple (1450) is known for its hardness and durability. This aesthetically beautiful hardwood features subtle and consistent grain patterns with distinctive brown heartwood and striking color variations across its planks.
  • White Maple (1450) is also one of the stronger hardwoods with grain patterns that are more subtle than Hickory or Oak. The natural color tones and neutral appearance of White Maple are in high demand for both traditional and contemporary settings.
  • White Oak (1360) has dense fibers that make for exceptionally durable floors. With dramatic grain patterns and color tones that feature nutty brown and cocoa hues, White Oak is comfortable in a wide range of designs, from casual to formal to contemporary.
  • Rift and Quartersawn White Oak (1360) produces strikingly beautiful floors with straight parallel lines that run the entire length of the plank, thanks to special cutting techniques.
  • Ash (1320) offers neutral and natural hues with many color variations and a meandering grain pattern. Natural Ash hardwood flooring may feature colors from light blonde to cream to rich nutty brown.
  • Red Oak (1290) is known for its deep, salmon tones in the heartwood and for tight, consistent grain that yields boards of exceptional widths and lengths.
  • Birch (1260) features intriguing combinations of color tones that run from blonde to warm amber to rich reddish-brown. White Birch flooring is renowned for its varying grain patterns that range from subtle swirls to flamelike effects.
  • Walnut (1010) is prized for its complex grain patterns, rich chocolate hues and surprising purple undertones. One of the most attractive yet resilient woods available, Walnut is suitable for everything from rustic country kitchens to high-rise city lofts to elegantly formal sitting rooms.
  • Cherry (995) floors will darken over time – the rich red tones in a Cherry plank will mature to a burnished auburn color as the floor ages. American Cherry wood flooring features subtle but distinctive grain structure and is one of the most popular of all hardwood floors.
  • Heart Pine (1225) has a density that rivals Oak and hues that range from pumpkin and amber to darker, more modern colors.
  • Eastern White Pine (380) is a softwood that wears in over time to create a floor with a distinct lived-in appearance. Eastern White Pine offers smooth grain, subtle knots and lighter hues that can be treated with a wide variety of finishes.

Frequently Asked Questions

What is the Janka hardness test?

The Janka hardness test determines the density of wood and its resistance to scratches, dents and wear. The test measures the amount of force required to embed a small steel ball halfway into a plank of wood. The results of the hardness test are listed as pounds of force (pounds-force or lbf) in the Janka wood hardness chart, or Janka Hardness Scale.

What is a good Janka hardness rating?

While most flooring options have a Janka rating of 950 or higher, ratings on the Janka wood hardness chart are neither good nor bad. Softer hardwoods like Cherry and Walnut may show more wear but can be extraordinarily beautiful and long-lasting. Even floors made of Pine, a softwood rather than a hardwood, have been known to last for a hundred years or more. The wood becomes more compressed as it is walked on and its durability increases. Because exceptionally dense hardwoods can be harder to work with and require more labor and cost, some homeowners and installers prefer softer woods like Walnut and Pine.

What is the hardest wood for floors?

The hardest wood used for flooring is Ipe, also known as Lapacho, but it is very rare and expensive. The hardest wood commonly used for flooring is Hickory, which has a rating of 1820 on the Janka wood hardness chart.
