So, in this article, we’ll explore is Spruce a hardwood, how hard is Spruce with its characteristics, its pros, and cons with uses.

Furthermore, I’ll answer some frequently asked questions about the hardness of Spruce compared to other wood types as well.

So, let’s jump in!

How Hard Is Spruce?

Spruce is softer than hardwoods and most softwoods as well.

According to the Janka hardness ratings, Spruce has a hardness rating of 510 lbf (2,268 N) which is relatively lower than many other kinds of wood.

They’re different species of Spruce which has nearly similar kind of properties and similar hardness values.

Here’re the Spruce wood species with their hardnesses,

• Sitka Spruce with a hardness rating of 510 lbf (2,268 N).
• White Spruce with a hardness rating of 480 lbf (2,135 N).
• Black Spruce with a hardness rating of 520 lbf (2,313 N).
• Engelmann Spruce with a hardness rating of 390 lbf (1,734 N).
• Red Spruce with a hardness rating of 490 lbf (2,135 N).

As you can see Spruce wood has different varieties with different colors. But when it comes to the hardness, all are nearly the same.

All the Spruce species have lower hardness, and all are considered softwoods.

When we look at the fiber structure of Spruce wood, it is lacking in pores and has small scarce resin canals.

Spruce has a closed pore structure. Those resin canals inside Spruce heal wounds and once cut those resin canals stiffen the lumber. These hardened resin canals are very stiff and lightweight.

Therefore, even though Spruce is considered as a softwood, it has a good density with superior qualities which surpass the properties of hardwoods as well.

Spruce comes from gymnosperm trees which are evergreen conifers.

They have needles and cones. When investigated under a microscope mostly there are no visible pores in the structure.

In terms of density, Spruce is a low dense wood than most of hardwoods.

The density of Spruce wood is around 400 kg/m³.

So, let’s have a look at the hardness of Spruce according to the Janka hardness scale.

Tip: Janka hardness test is the standard method to measure the hardness of any wood according to its resistance to wear and dent.

Woods with high wear and dent resistance score higher values in Janka hardness ratings.

According to the Janka hardness ratings, Spruce has a hardness rating of around 490 lbf (2,135 N) – 520 lbf (2,313 N).

Do you know how to identify Spruce wood properly? Don’t worry! I’ll explain.

How Can You Identify Spruce Wood?

Identifying spruce wood, like any other wood, requires a keen eye for detail and a basic understanding of the characteristics that make this wood unique.

Here’re some features you can use to identify spruce wood,

• Observe the color and texture
• Consider the weight and hardness
• Examine the growth rings
• Smell the Wood

Let’s discuss those features in detail.

Observe the Color and Texture

Firstly, let’s consider the color of spruce wood. Spruce typically exhibits a pale color with a hint of yellow or red, varying slightly depending on the specific type of spruce.

For instance, Norway spruce features brown to reddish-brown heartwood surrounded by white sapwood.

The Engelmann spruce, on the other hand, has a yellow-to-white heartwood.

Spruce wood is also characterized by its fine, straight grain, and an even texture.

These traits give spruce a uniform appearance, which can be a strong clue when you’re trying to identify this type of wood.

Consider the Weight and Hardness

As a softwood, spruce has a lightweight and relatively low hardness level.

To put it into perspective, spruce ranks on the lower end of the Janka hardness scale, which is a measure of the resistance of wood to wear and denting.

For instance, Norway spruce has a Janka rating of 380, and Engelmann spruce has a rating of 390.

Comparatively, red oak, a common hardwood, has a Janka rating of 1,290.

Examine the Growth Rings

One unique feature of spruce wood that can help in its identification is its growth rings.

Spruce trees have closed growth rings, which contribute to their suitability as a tonewood for musical instruments.

This might be a more advanced identifying feature, but for seasoned woodworkers or anyone involved in the creation of musical instruments, it’s a telling sign.

Smell the Wood

You might be surprised to know that smell can also be a distinguishing factor!

The scent of spruce wood is often described as being fresh and sharp, similar to the smell of the forest after a rain.

This characteristic aroma can help experienced woodworkers identify spruce wood.

So, let’s find out what are the characteristic qualities of Spruce overcome the lower hardness of Spruce to become one of the most superior wood types on the planet.
