Types of Wood: A Complete Guide to Species & Uses
Types of wood divide into three families: hardwoods from broad-leaved trees (oak, maple, walnut), softwoods from conifers (pine, cedar, fir), and engineered wood made from fibers or veneers (plywood, MDF). The right choice depends on the job — strength and grain for furniture, cost and workability for framing, moisture resistance for outdoors, and stability for panels.
Quick Answer
There are three main types of wood: hardwood (dense, durable, for furniture and floors), softwood (lighter, cheaper, for building and outdoor use), and engineered wood (stable, low-cost, for panels and cabinetry). The terms “hardwood” and “softwood” describe the tree, not the actual hardness — measured separately on the Janka scale.
What are the main types of wood?
Wood is grouped by the tree it comes from and how it is processed. According to the USDA Forest Products Laboratory, the hardwood/softwood split is botanical — it refers to the tree species, not the density of the timber. That is why balsa (a hardwood) is feather-light while longleaf pine (a softwood) is harder than several hardwoods.
- Hardwoods — from deciduous, broad-leaved trees. Dense, strong, prized for grain; used in fine furniture, flooring, and cabinetry.
- Softwoods — from evergreen conifers. Lighter, faster-growing, easier to cut; used for framing, decking, and outdoor projects.
- Engineered wood — manufactured from veneers, chips, or fibers bonded under heat and pressure. Stable, affordable, available in large sheets.
Hardness itself is measured on the Janka scale (pounds-force to embed a steel ball) — the industry standard. Higher = harder and more dent-resistant. See which woods are lightest and hardest.
Hardwood vs softwood: what’s the difference?
The core difference is the tree, not the hardness. Hardwoods come from slow-growing deciduous trees and are usually denser, pricier, and more decorative; softwoods come from fast-growing conifers and are cheaper and easier to work. Here is how they compare at a glance:
| Feature | Hardwood | Softwood |
|---|---|---|
| Tree type | Deciduous (broad-leaved) | Coniferous (evergreen) |
| Growth speed | Slow | Fast |
| Density (usually) | Higher | Lower |
| Cost | Higher | Lower |
| Grain | Often complex / decorative | Usually straight / plain |
| Typical use | Furniture, floors, cabinets | Framing, decking, cheap builds |
Wood grain and appearance
Grain — the pattern of wood fibers — affects both looks and workability. Open-grain woods like oak and ash have visible pores and need grain filler for a glass-smooth finish, while closed-grain woods like maple and cherry are naturally smooth. Grain direction can be straight, interlocked, or figured (curly, quilted, or bird’s-eye maple) — figure raises a board’s value but makes planing trickier.
Common hardwood types and their uses
Hardwoods are the first choice for furniture and floors because they resist wear and show beautiful grain. In our own project work, the species below cover the vast majority of real builds:
- Red & White Oak (Janka ~1290–1360) — Strong, affordable, with a bold open grain. Red oak is warmer-toned and cheaper; white oak is denser and water-resistant (closed grain), so it suits kitchens, boats, and outdoor furniture. Best for: Furniture, flooring, cabinets, barrels. Watch out: Very hard to work by hand; red oak is porous and less water-resistant.
- Hard Maple (Janka ~1450) — Pale, fine, and very hard with a smooth surface that takes finish evenly. Cutting boards, worktops, and painted cabinetry. Best for: Worktops, cutting boards, floors, painted cabinets. Watch out: Can blotch when stained; heavy.
- Black Walnut (Janka ~1010) — Premium dark chocolate-toned hardwood that machines and carves beautifully. The go-to for heirloom furniture and feature pieces. See how it compares in hardness. Best for: Fine furniture, gunstocks, veneer, feature pieces. Watch out: Expensive; color can lighten in sunlight.
- Cherry (Janka ~950) — Smooth, straight grain that darkens richly with age to a warm reddish-brown. A favorite for fine furniture and cabinetry. Best for: Fine furniture, cabinetry, trim. Watch out: Softer than oak; darkens unevenly if light exposure is uneven.
- Ash (Janka ~1320) — Light-colored, strong, and shock-resistant with an oak-like grain. Traditional for tool handles, baseball bats, and bent furniture. Best for: Tool handles, sports gear, furniture, flooring. Watch out: Susceptible to the emerald ash borer; supply is shrinking.
- Hickory (Janka ~1820) — The hardest common domestic hardwood — extremely tough and shock-resistant. Rustic flooring and tool handles. Best for: Flooring, tool handles, cabinets. Watch out: Hard on tools and blades; can be difficult to stain evenly.
- Birch (Janka ~1260) — Affordable, pale, fine-grained; often used as a budget alternative to maple and as the face veneer on quality plywood. Best for: Plywood, cabinets, furniture, toys. Watch out: Prone to blotching; less rot-resistant.
- Poplar (Janka ~540) — A soft, inexpensive, easy-to-work hardwood. Technically a hardwood but soft — ideal for painted trim, drawers, and beginner projects. Best for: Painted furniture, trim, drawer boxes. Watch out: Too soft for high-wear surfaces; greenish streaks.
Premium and exotic hardwoods round out the group: mahogany (~800) and teak (~1,070) are prized for their rich color and outstanding weather resistance — teak’s natural oils make it the standard for outdoor and marine furniture. Mango wood (~1,070) is a sustainable, budget-friendly choice, while purpleheart (~1,860) is a dramatic, naturally purple exotic used for accents and turning.
Common softwood types and their uses
Softwoods grow faster, cost less, and are easier to cut, which makes them the backbone of construction and outdoor work:
- Pine (Janka ~380–870) — Inexpensive, light, and everywhere. Eastern white pine (~380) is soft and knotty; Southern yellow pine (~870) is much harder and used structurally. The default for framing, shelving, and beginner DIY. See is pine a hardwood?. Best for: Framing, shelving, DIY, furniture. Watch out: Dents easily (white pine); knots and sap.
- Cedar (Janka ~350) — Lightweight and naturally rot- and insect-resistant thanks to its aromatic oils — ideal outdoors and in closets. Western red and aromatic red cedar are the common types. Best for: Decking, fencing, closets, outdoor furniture, siding. Watch out: Soft and dents easily; splinters.
- Douglas Fir (Janka ~660) — Strong and stiff for its weight, which is why it is a top structural framing lumber. Also used for beams and flooring. Compare SYP vs SPF lumber and what fir is used for. Best for: Framing, beams, plywood, flooring. Watch out: Splinters; not naturally rot-resistant.
- Spruce / Whitewood (Janka ~510) — “Whitewood” is a lumberyard label usually covering spruce, pine, or fir (SPF) sold for general construction. See what is whitewood. Best for: Construction framing, crates, general DIY. Watch out: Low rot resistance; not for outdoor use untreated.
- Redwood (Janka ~450) — Lightweight, straight-grained, and highly rot-resistant like cedar — a premium outdoor wood on the US West Coast. Best for: Decking, outdoor furniture, siding. Watch out: Expensive; soft and dents.
Engineered wood types
Engineered boards trade natural grain for stability, large sheet sizes, and lower cost. They resist warping and are ideal wherever a flat, uniform surface matters:
- Plywood — thin veneers glued in alternating cross-grain layers for strength and stability. Grades run from rough sheathing to cabinet-grade birch. Used for panels, subfloors, and cabinet carcasses.
- MDF — medium-density fiberboard with a smooth, grain-free surface, perfect for painted cabinetry and trim. Heavy, and it swells if it gets wet.
- Particle board — the most economical panel, made from wood chips and resin; common in flat-pack furniture. Weakest of the engineered boards.
- OSB — oriented strand board, made from compressed wood strands; strong and cheap, used for sheathing and subfloors.

Key wood terms
Janka hardness is the industry-standard measure of how well a wood resists denting and wear, in pounds-force.
Grain is the pattern and direction of a wood’s fibers, which affects strength, look, and how it machines.
Figure is the decorative pattern in some wood (curly, quilted, bird’s-eye) that raises its value.
Hardwood vs softwood is a botanical split — hardwoods come from broad-leaved trees, softwoods from conifers; it describes the tree, not the density.
Kiln-dried is wood dried in a controlled oven to a low, stable moisture content so it stays flat and takes finish well.
Quarter-sawn is lumber cut so the growth rings run roughly vertical, giving a straight grain that resists warping.
Engineered wood is boards made from veneers, chips, or fibers bonded under heat and pressure (plywood, MDF, OSB) for stability and low cost.
How do you choose the right type of wood?
Match the wood to the demands of the project — durability, moisture exposure, finish, and budget:
| Project | Best wood type | Why |
|---|---|---|
| Furniture & cabinets | Hardwood (oak, maple, walnut) | Durability + attractive grain |
| Outdoor / decking / trim | Cedar, redwood, teak, treated softwood | Rot & moisture resistance — see best wood for exterior trim |
| Painted projects & panels | MDF, plywood, poplar | Smooth, stable surface |
| Budget builds & framing | Pine & other softwoods | Low cost, easy to work |
| High-wear floors & worktops | Hickory, maple, white oak | Highest Janka hardness |
Frequently asked questions
Is hardwood always harder than softwood?
No. The terms describe the tree, not the density. Balsa is a hardwood but extremely soft, while longleaf pine (a softwood, Janka ~870) is harder than poplar or cherry. Use the Janka scale to compare actual hardness.
What is the most versatile type of wood?
Pine is the most versatile budget wood for general use and framing, while oak is the most versatile hardwood when you need strength and a classic look at a reasonable price.
Which wood is best for beginners?
Pine and poplar are best for beginners — inexpensive, easy to cut and finish, and forgiving of mistakes. Avoid dense exotics like purpleheart or hickory until your tools and skills are ready.
What type of wood is best for outdoor use?
Naturally rot-resistant woods — cedar, redwood, and teak — are best outdoors, along with pressure-treated softwood for structural parts. Their oils or treatment resist moisture, insects, and decay.
What is the hardest type of wood?
Among common woods, hickory is the hardest domestic species at about 1,820 on the Janka scale. Exotic species like purpleheart (~1,860) and ipe (~3,680) are harder still.
Which wood is cheapest?
Pine, poplar, and engineered boards like particle board and OSB are the cheapest. Pine is the most affordable solid softwood; particle board is the cheapest panel.
