Chances are you’re surprised with how admirable a Spruce’s quality is, whether on foundations, crates, or in generating energy. Truly, it’s an asset in the workshed.
However, it can be hard to tell if spruce is a hardwood or softwood. So, we’re here to get into more details about Spruce wood, guided by our wood experts.
Wood Classification of Spruce and its Janka Hardness Rating
The elasticity and lightness of spruce wood have made it popular amongst woodworkers. However, its durability doesn’t make it a hardwood. The genus Picea native, spruce, is often softer than most softwoods, so generally, it’s not a hardwood.
Spruce wood comes from an evergreen tree called coniferous as it grows cones and is popular amongst the northernmost region, like pine wood and birch.
Spruce woods come in different colors and varieties, hence are alike in hardness. All spruce types and species are softwoods with impressive density and superior qualities, so it’s often mistaken as a hardwood.

The fiber structure of spruce wood lacks pores and has small resin canals. When the resin canals inside the spruce wood are cut, it stiffens the spruce lumber causing the hardened resin canals to be stiff and lightweight.
The Spruce wood has a Janka hardness rating of 510lbf, deemed lower than most wood types. However, the hardness rating varies a little based on the type of spruce wood. Let’s take a look at their hardness rating below.
Sitka Spruce | 510 lbf (2,268 N) |
Engelmann Spruce | 390 lbf (1,734 N) |
Black (Type of Spruce) | 520 lbf 2,313 N) |
Red (Type of Spruce) | 490 lbf (2,135 N) |
When you look at spruce wood in a microscope, you will see no visible pores in its structure, and it has cellulose fibers.

Determining whether your material is hard or soft wood may seem tricky, so most refer to the wood’s hardness rating instead. Now, let’s assess the Spruce wood in the Janka scale, and see which other softwood and hardwoods it compares to.
Wood Species | Hardness Value |
Red Mahogany and Turpentine | 2,697 lbf (12,000 N) |
Brazilian Walnut | 3,684 lbf (16,390 N) |

Spruce Trees
Spruce trees are trees that come from the genus Picea and grow at a quick pacing of about 8 to 12 inches per year.

Other spruce trees, however, grow faster such as the Norway spruce that grows up to 3 feet per year, and sometimes this hardwood grows even quicker depending on the weather.
Hence the tallest species of Spruce wood, known as the Sitka softwood, grows up to 250-350 feet once it reaches maturity.
Characteristics of Spruce Wood
There’s a reason why Spruce woods stand out in the woodworking industry, and its tail of characteristics will explain why. You’re also probably wondering whether it’s a hard or soft wood so let’s talk about spruce, its origin, and its uses.
Color | Yellowish white (some spruce tree are reddish brown) |
Density | A spruce’s average density is around 400 kg/m3. |
Wood type | Trees from a gymnosperm, like that spruce, are considered softwoods, while those like pine are considered hardwoods. |
Hardness | 490 lbf – 520 lbf |
Applications | Furniture, Christmas trees, crates, lumber, and even paper pulp |
Qualities of Spruce
- High workability
- Softwood
- Poor weather resistance
- Lightweight softwood
- Low hardness and density
- Light colored wood
- Great strength-to-weight ratio
- It has open and large grain
Ideal Uses of Spruce

Now that we’ve made it safe to say that spruce wood is not a hardwood, what other projects can you make out of this softwood and lightweight material?
Musical Instruments
Apart from their lightweight characteristic, spruce trees also have growth rings that make them an excellent material for creating musical instruments. The rings enable sound texture and impressive tonal quality that enhances all sounds from the wood.
The genus Picea is a versatile wood with many musical instruments you can make out of spruce softwoods, such as piano soundboards, violins, and even the top of guitars. To top it off, the uniform appearance makes all the difference.
Paper Products
Spruce woods generally have this cellulose fiber, making it a common raw material in making paper products and even paper itself. The long fibers in these softwoods present forms together, giving paper sufficient strength and texture to grasp together, even when making very thin sheets.
Crates And Boxes
Since spruce woods are stiff and straight, they are preferred for making boxes and crates. Using spruce makes the task more affordable and efficient since it’s lightweight and doesn’t need a huge force when moving it.

Boats And Planes
The largest plane ever built is known as the Spruce Goose, engineered by Howard Hughes. So if you’re asking if the Spruce goose means Spruce wood itself, it is. Even if it is considered a lightweight softwood, you’ll be surprised by how durable a Spruce is.
Since spruce woods are softwoods, sturdy enough to withstand air, and have a moderate resistance to decay and rot, it’s an ideal raw material for making early biplanes and military fighter planes.
Construction Projects
Spruce woods are most commonly seen in construction, and like pines, it’s also used as a common framing wood and a material to generate energy.
Using such plywood is also common in construction projects because it’s lightweight and stable, and the stiff qualities are outstanding, almost close to that of hardwoods.
Spruce Wood’s Strength
Spruce woods come from evergreen conifers and are like firs and pines, inexpensive and readily available. It also has uniform sets of straight grain and even texture which is easy to work with like other softwoods. The heartwood of spruce woods is also moderately rot-resistant.

Since these types of woods are lightweight, it’s also popular for their workability. Like other softwoods, spruce is easy to shape and bend, and working your way around the knots isn’t difficult either way.
Benefits and Drawbacks of Spruce Wood
While spruce woods are commendable, there are still a few characteristics that you should consider before purchasing one. Here, we’ll enumerate the pros and cons of spruce wood.
Pros
- High flexibility
- Easy to finish
- Lightweight
- High Workability
- Excellent bending strength and compression
- Affordable Price
- Impressive strength-to-weight ratio
- Aesthetic uniform texture
Cons
- Poor hardness and density
- Prone to insect attacks
- Poor decay resistance
- Less durability
- Low weather resistance
- Susceptible to the blotchy surface when the stain is not wiped well
Which is Harder: Spruce or Pine?
Spruce species are harder than Pinewood. Other wood types are often compared to spruce due to their popularity. The infamous resin canals [1] of spruce that heal wounds add to its value.
The cut resin canals stiffen the lumber and therefore make it lightweight. Now in the Janka hardness rating, here is how the two kinds of wood would compare.

Is Oak Harder Than Spruce?

With oak often used as a construction material, it’s significantly harder than Spruce. Oaks are hardwoods, so it’s no question that it’s harder and more durable than Spruce.
Hardwoods often come from angiosperms, while spruce woods come from gymnosperm trees. Here’s how the two wood types look on the Janka hardness.
Wood Type | Hardness |
Red Oak | 1,290 lbf (5,738 N) |
White Oak | 1,360 lbf (6,050 N) |
Red Spruce | 490 lbf (2,180 N) |

White Spruce | 480 lbf (2,135 N) |
Sitka Spruce | 510 lbf (2,268 N) |
Engelmann Spruce | 390 lbf (1,735 N) |
Spruce or Cedar: Which is Harder?

Woods like Red Cedar is harder than spruce. However, there are woods that are softer than spruce, specifically White Cedar. While both softwood and specie type, there’s a significant difference between red and white cedar, and here’s how it looks on the Janka hardness ratings.
Wood Type | Hardness |
Red Cedar | 900 lbf (4,003 N) |
White Cedar | 320 lbf (1,423 N) |
Red Spruce | 490 lbf (2,180 N) |

Sitka Spruce | 510 lbf (2,268 N) |
Engelmann Spruce | 390 lbf (1,735 N) |
Spruce Wood or Douglas Fir: Which is Harder?

Douglas fir is wood from a coniferous tree but is harder than spruce. Like Spruce, it’s also native to northern North America, has different varieties, and closed growth rings. Here’s how it’s scaled in the Janka hardness rating.
