Choosing Wood Species for Woodworking Projects

Choosing the right wood for a project is a matter of matching the species’ properties to the demands of the piece. The wood’s hardness, stability, workability, cost, and how it finishes all matter. The species available at a typical lumberyard fall into two broad categories: hardwoods and softwoods. The names are botanical, not descriptive of actual hardness. Balsa is a hardwood; Douglas fir is a softwood. For furniture and interior work, hardwoods are the usual choice because they machine cleanly and take finishes well. For framing, sheathing, and outdoor structures, softwoods are cheaper and often naturally resistant to decay.

This guide covers the species most likely to be found at a lumberyard, what each is good for, and where each is a poor choice. A comparison table summarizes the key properties. The final section covers the most common mistake made when selecting wood: assuming that a wood’s hardness or price makes it suitable for every use.

Understanding Wood Properties

Hardness

Hardness is the wood’s resistance to dents and wear. The Janka scale measures the force required to embed a steel ball halfway into the wood. Higher numbers mean harder wood. Harder woods are better for tabletops, floors, and other surfaces that see abuse. Softer woods dent easily and are better for decorative pieces, drawer sides, or where weight is a concern.

Stability

Stability refers to how much the wood moves with changes in humidity. Wood expands and contracts across the grain as it gains or loses moisture. Stable woods move little, making them ideal for wide tabletops, drawer fronts, and panels. Unstable woods can cup, twist, or split if not properly accommodated. Quartersawn stock is more stable than flatsawn, but species also differ in inherent stability.

Workability

Workability describes how easily the wood is cut, shaped, and sanded. Some woods tear out easily, some blunt tools quickly, and some split when nailed. For hand tools, softer woods are easier, but they can crush under clamping pressure. Harder woods require sharp tools and careful technique. Exotic woods may contain silica that dulls blades rapidly.

Cost and Availability

Cost varies by region and market, but some general patterns hold. Softwoods are cheaper than hardwoods. Among hardwoods, domestic species like oak, maple, and cherry are less expensive than imported exotics. Figured wood (curly, quilted, bird’s-eye) commands a premium. Availability also matters: a species may be cheap where it is harvested but costly elsewhere.

Hardwood Species

Oak (Red and White)

Oak is the workhorse of North American hardwoods. Red oak is porous and has a prominent grain; white oak is denser and naturally rot-resistant. Both are hard and durable, but they are not especially stable—they move noticeably with humidity. Oak machines well, but it blunts tools faster than softer woods. It takes finishes well, though open pores can require grain filling for a smooth surface. White oak is a good choice for outdoor furniture because of its decay resistance. Red oak is not suitable for outdoor use.

Maple (Hard and Soft)

Hard maple (sugar maple) is among the hardest domestic woods. It is light-colored, fine-grained, and takes a beating. It is excellent for workbenches, butcher blocks, and any surface that will see heavy use. Hard maple is difficult to work with hand tools because it is hard and can burn when power sanded. Soft maple (silver maple) is easier to work and still fairly hard, but it is not as durable. Both are stable once dried. Maple is a poor choice for outdoor projects unless it is properly finished and maintained.

Cherry

Cherry is prized for its warm, reddish-brown color that deepens with age. It is moderately hard, stable, and machines beautifully. Cherry is forgiving of less-than-perfect technique—it sands well and takes finishes evenly. It is a classic choice for fine furniture and cabinets. Cherry is not suitable for outdoor use. It is also prone to blotching when stained, so a sanding sealer or a natural finish is often used.

Walnut

Walnut is a premium hardwood with a rich, dark chocolate color. It is stable, moderately hard, and works well with both hand and power tools. Walnut is less prone to tear-out than many woods, making it a favorite for carving and turning. It finishes beautifully and is used for high-end furniture, gunstocks, and musical instruments. Walnut is expensive, but its beauty justifies the cost for many projects. It is not rot-resistant and should not be used outdoors.

Poplar

Poplar is a cheap, soft hardwood with a greenish or purple tint. It is easy to work, stable, and takes paint well. Poplar is often used for painted furniture, drawer boxes, and interior trim. It is not strong or hard enough for heavy-duty furniture, and it is not attractive when clear-finished. Poplar is a poor choice for anything that will be visible without paint.

Mahogany

Mahogany (genuine or African) is a classic furniture wood known for its deep reddish-brown color and straight grain. It is stable, easy to work, and rot-resistant, making it suitable for both indoor and outdoor furniture. Genuine mahogany is expensive and increasingly scarce; African mahogany is more affordable but less stable. Mahogany takes finishes exceptionally well. It is a good choice for fine furniture, boat interiors, and exterior doors.

Softwood Species

Pine (Eastern White, Ponderosa, Radiata)

Pine is the most common softwood at lumberyards. It is cheap, light, and easy to work. Eastern white pine is soft and stable, making it good for carving and interior trim. Ponderosa pine is similar. Radiata pine is often used for construction and is harder than white pine. Pine is prone to dents and scratches, so it is not ideal for tabletops or high-wear surfaces. It takes paint well but can blotch when stained. Pine is not rot-resistant unless treated.

Cedar (Western Red, Eastern Red)

Cedar is naturally rot-resistant and aromatic. Western red cedar is light, stable, and easy to work. It is the standard for outdoor furniture, decking, and siding. Eastern red cedar (actually a juniper) is more aromatic and is used for chests and closet linings. Cedar is soft and dents easily, so it is not for heavy-use surfaces. It finishes well with clear oils or varnishes, but it can be blotchy.

Douglas Fir

Douglas fir is a strong, stiff softwood used for framing and structural applications. It is not as rot-resistant as cedar but is more so than pine. Douglas fir is hard for a softwood and takes nails well. It is often used for exterior projects if treated or finished. The grain is pronounced, and it can be difficult to get a smooth finish. It is a poor choice for fine furniture because of its coarse texture.

Redwood

Redwood is another naturally rot-resistant softwood, similar to cedar. It is stable, easy to work, and takes finishes well. Redwood is used for outdoor furniture, decks, and siding. It is soft and can be dented, but its durability outdoors makes it a favorite. Redwood is more expensive than cedar and is becoming less available.

Choosing Wood for Outdoor Projects

For outdoor use, the primary concern is rot resistance. Cedar, redwood, and white oak are naturally resistant to decay. Teak and ipe are tropical hardwoods with excellent rot resistance, but they are expensive and can be difficult to work. Pressure-treated pine is cheap and rot-resistant, but it is not attractive and can warp. For outdoor furniture, cedar or white oak are good choices. For decking, cedar, redwood, or pressure-treated pine are common. Avoid woods like maple, cherry, and walnut outdoors—they will rot quickly unless protected by a high-quality finish, and even then, maintenance is constant.

The Most Common Mistake: Assuming Hardness Equals Quality

A frequent error is choosing the hardest wood for every project, thinking it is the best. Hardness is only one property. A hard wood like maple is excellent for a workbench, but it is a poor choice for a carved decorative piece because it is difficult to shape. Similarly, a soft wood like pine is often dismissed as low quality, but it is ideal for carving and for painted furniture. The real mistake is not considering stability, workability, and the project’s requirements. A stable wood like cherry is better for a wide tabletop than a harder but less stable wood like oak, which will move more and may crack. The right choice depends on the specific demands of the piece, not on a single property.

Another aspect of this mistake is ignoring the wood’s intended finish. Some woods, like cherry and walnut, are beautiful with a clear finish. Others, like poplar, are best painted. Choosing a wood that does not match the finish can lead to disappointment. Always consider how the wood will look and behave after finishing.

Frequently Asked Questions

What is the best wood for furniture?

The best wood for furniture depends on the piece. For fine furniture, cherry and walnut are excellent for their stability and beauty. For sturdy, everyday furniture, oak and maple are good choices. For painted furniture, poplar is economical and easy to work. Consider the piece’s use, the desired look, and the budget.

What is the difference between hardwood and softwood?

Hardwood comes from deciduous trees that lose their leaves, while softwood comes from conifers that are usually evergreen. The names are botanical, not descriptive of hardness. Balsa is a hardwood, and Douglas fir is a softwood. In general, hardwoods are denser and harder, but there are exceptions. Softwoods are often cheaper and more readily available.

What wood is best for outdoor use?

Cedar, redwood, and white oak are naturally rot-resistant and good for outdoor furniture. Pressure-treated pine is a cheaper option for structural projects. Tropical hardwoods like teak and ipe are extremely durable but expensive. Avoid woods like maple, cherry, and walnut outdoors.

How do I read a wood species chart?

A wood species chart lists properties like hardness (Janka rating), stability, workability, and cost. Use it to compare species. Look for a wood that matches the needs of your project. For example, if you need a stable wood for a tabletop, choose a species with high stability. If you need a hard surface, choose a high Janka rating.

Is pine good for woodworking?

Pine is good for many woodworking projects. It is easy to work, cheap, and stable. It is ideal for carving, interior trim, and painted furniture. However, it is soft and dents easily, so it is not suitable for high-wear surfaces like tabletops. It also can blotch when stained, so a conditioner is often used.
