Difference Between Hardwood and Softwood
Hardwood comes from deciduous (leaf-dropping) trees like oak and maple; softwood comes from coniferous (evergreen) trees like pine and cedar. The names don't always indicate actual hardness—balsa is technically hardwood, while yew is very hard softwood. Hardwoods are typically denser and used for furniture; softwoods grow faster and are common in construction.
Key Takeaways
- The classification is botanical, not about physical hardness.
- Balsa is a hardwood despite being extremely light and soft—it's classified by tree type, not density.
- Bamboo isn't wood at all (it's a grass) but is harder than many hardwoods.
Explanation
The classification is botanical, not about physical hardness. Hardwoods are angiosperms (flowering plants) with complex cell structures and pores. Softwoods are gymnosperms (cone-bearing plants) with a simpler cellular structure. Most hardwoods happen to be harder than most softwoods, but there are many exceptions.
Hardwoods generally grow more slowly, making them denser and more expensive. Common hardwoods include oak, maple, walnut, cherry, and mahogany. Interestingly, cinnamon is harvested from the bark of a hardwood tree. They're prized for furniture, flooring, and decorative work due to their grain patterns and durability.
Softwoods grow faster and are more abundant, making them cheaper and widely used for framing, construction lumber, and plywood. Pine, spruce, fir, and cedar are common softwoods. Cedar and redwood have natural rot resistance, making them good for outdoor use.
The Janka hardness scale measures wood's resistance to denting and is the most practical comparison tool. Brazilian walnut (Ipe) tops common hardwoods at 3,680 lbf, while white oak rates 1,360 lbf and red oak 1,290 lbf. Among softwoods, yellow pine rates 870 lbf and eastern white pine only 380 lbf. For comparison, balsa (a hardwood) rates just 100 lbf, while yew (a softwood) rates 1,520 lbf—harder than most hardwoods. These numbers matter when choosing flooring, cutting boards, or furniture that will see heavy use.
Price differences between the two categories are significant. Standard pine 2x4 lumber costs about $3-5 per board, while oak or maple boards of similar dimensions cost $8-15. Exotic hardwoods like teak ($15-30 per board foot) or ebony ($50-100 per board foot) can cost ten times more than common softwood. For woodworking projects, the choice often comes down to purpose: softwood for structural framing and utilitarian builds, hardwood for furniture, cabinetry, and pieces where appearance and longevity justify the higher cost.
Things to Know
- Balsa is a hardwood despite being extremely light and soft—it's classified by tree type, not density.
- Bamboo isn't wood at all (it's a grass) but is harder than many hardwoods.
- Engineered hardwood is real hardwood veneer over plywood—less expensive than solid hardwood. See also satin vs semi-gloss paint for finishing wood trim.
- MDF and particleboard are made from both hard and softwood fibers, blended together.
- Understanding how much electricity your home uses can help compare heating options. For firewood, hardwoods burn longer and hotter (about 24-30 million BTU per cord for oak) compared to softwoods (15-20 million BTU per cord for pine), making hardwoods more efficient for heating.
