If you are planning on building something out of real and solid wood, then you are on the right track. In terms of durability and appearance, there is really nothing better than actual lumber. That said, there are many different types of wood to consider, with mahogany and chestnut being two very common ones. Although both are popular, they’re also quite different from each other.

Today, we’re going to figure out what makes mahogany and chestnut different, and which one is best for specific purposes.

What Is Mahogany?

First is mahogany, which is a deciduous type of tree, meaning that it does lose its leaves during the colder seasons. This is a tropical hardwood tree, that is native to the warmer parts of the Americas, and can be found in Oceania and Asia due to exportation.

Mahogany is a very popular type of wood due to its appearance. It has a very straight and tight grain, sometimes interlocked in nature, combined with no gaps, voids, or knots. It also features a really beautiful deep reddish-brown color which tends to darken as time goes on.

As for the qualities, mahogany is very durable and strong. It features a hard structure combined with a high density, along with some natural oils and resin. This is a resistant type of wood in terms of physical impacts and damage, and is resistant to mold, fungus, pests, moisture, and rotting. For this reason, mahogany is a good choice for both indoor and outdoor applications.

Mahogany is a fairly expensive type of wood, which is due to both its durability and aesthetic appeal. It’s a common choice for high-end and luxury furniture, as well as high-quality doors, windows, cabinets, and more.

What Is Chestnut?

We then have the chestnut tree, which is native to North America, particularly the American chestnut tree. There are other types of chestnut trees, mainly the Chinese chestnut, although what we typically use for construction is the American variety. The chestnut tree is a deciduous tree, just like mahogany, and is also a hardwood.

That said, in terms of hardness, chestnut is actually the softest hardwood found in North America, therefore making it more durable than softwoods, but the least durable hardwood. Chestnut wood also isn’t overly dense, which makes it quite lightweight.

However, chestnut wood does contain a good deal of natural oils and resin, and due to its nature, is very resistant to pests, fungus, and moisture. In terms of outdoor use and weather resistance, chestnut wood is one of the best options out there.

When it comes to appearance, chestnut wood has a fairly straight grain, although it may also be wavy or interlocked, combined with a medium to coarse texture. This wood can contain quite a few knots and voids and tends to be a light to moderate brown in color which may darken over time.

Chestnut wood can be relatively expensive, which is why it is often used for smaller purposes, such as for furniture, windows, and doors, although if you are willing to pay the high cost, it can also be used for flooring, walls, and everything in between.

Mahogany vs. Chestnut: What Are the Differences?

Now that we know what both mahogany and chestnut wood are, let’s figure out what makes them different from each other.


Chestnut is one of the softest hardwoods out there, coming in at just 540 lbf on the Janka hardness scale. Mahogany, on the other hand, comes in at roughly 900 lbf.

This makes it much harder than chestnut, and therefore more resistant to physical damage, such as denting and scratching.

Density and Weight

Just like mahogany is much harder than chestnut, it is also much denser and heavier.

Mahogany wood comes in at between 49 and 56 lbs per cubic foot, depending on the specimen. Chestnut comes in at roughly 28 lbs per cubic foot, therefore making it about half as heavy and dense as mahogany. This is something that leads to mahogany being more durable, but also heavier and harder to work with.

Pest and Moisture Resistance

You would think that due to its hardness and density, that mahogany would be more pest and moisture-resistant than chestnut wood, but this is not the case. Chestnut wood, both due to its resin and natural oils, as well as other reasons, is more moisture and rot-resistant than mahogany. There are chestnut trees out there that have been dead for decades, yet are still standing and in good condition.

Strength and Overall Durability

Although chestnut may be the better option for outdoor use due to its moisture resistance, it’s not nearly as strong as mahogany.

Appearance – Grain and Color

Mahogany has a much smoother texture, a straighter grain, far fewer imperfections, and a much deeper reddish-brown color than chestnut, which is coarser, not as straight, has some imperfections, and is lighter in color.


Chestnut can be hard to work with due to having some knots, but because of the hardness and density of mahogany, it is usually considered the harder of the two to work with.


Mahogany is relatively expensive, coming in at around 15 dollars per board foot, although chestnut can cost just as much, if not more.

When to Use Mahogany Wood?

If you want something super hard, durable, dense, and good-looking, particularly for indoor and outdoor furniture, doors, windows, and decorative pieces, then mahogany is the way to go.

When to Use Chestnut Wood?

If you need wood that is super moisture-resistant and looks nice, then chestnut makes for a fine option. When it comes down to it, chestnut can be used for a wide variety of applications including floors, walls, furniture, and more. Just beware that it’s not overly resistant to physical damage.

Alternatives to Mahogany and Chestnut Wood

If what you are looking for is maximum hardness and durability, some good options include African pearwood, Brazilian walnut, ebony, snakewood, hickory, and ironwood.

As you can see, both mahogany and chestnut are fine woods to use in their own rights, however, they do have some major differences between them, so choose wisely!
