The Surprising Hardness of Spruce

When it comes to determining wood hardness levels, few tests are more insightful than the Janka hardness scale.

Used globally as the standard for measuring a wood’s resistance to denting and wear, Janka ratings provide an objective look at a species’ relative hardness compared to others. So where does Spruce land on this crucial scale? You may be surprised.

While commonly labeled a “softwood,” the reality is Spruce possesses an admirable hardness quotient.

Taking samples from five major Spruce species, ratings ranged from a low of 390 lbf for Engelmann Spruce up to 520 lbf for Black Spruce. For context, Cherrywood measures around 995 lbf while northern Red Oak comes in at 1290 lbf.

So while Spruce can’t compete with true hardwood heavy hitters, it more than holds its own against many other softwoods.

White Pine, for example, has a Janka score of only 420 lbf. Even Sugar Pine lags behind at just 380 lbf of force resistance.

Digging deeper, small variances emerge between Spruce varieties. Sitka Spruce demonstrates good overall hardness at 510 lbf while White Spruce is slightly softer at 480 lbf. Red Spruce also shows praiseworthy dent resistance with a Janka rating near 490 lbf of force.

Beyond published averages, the compact cellular structure of Spruce plays a key role. Resin-filled tracheids allow it to withstand impact and pressure remarkably well for its density. Over time, these dense, interlocking fibers self-season and harden further for added durability.

So while frequently promoted as a “softwood,” the objective science reveals Spruce deserves more respect when it comes to absolute hardness.

Compared to other common woods, its impressively high Janka scores demonstrate surprising density and strength belied by its lightweight nature. Proper classification shows Spruce has earned the right to be considered no “soft” pushover.
