Stairs take more punishment than almost any floor in the house. Picking the right species means weighing hardness, grain, color and how much character you want the wood to gain over time.
Everyone who uses a stair walks the same narrow path. Feet land in the same places, pets scrabble on the same edges and furniture is dragged across the same nosings. The wear is concentrated, which is why a species that is fine for a bedroom floor can look tired on a stair after a short time.
A harder wood resists denting, but hardness is not the only factor. Color, grain pattern, finish and how well the wood takes stain all matter. A species that you love the look of and will maintain is a better pick than the hardest one on paper.
Janka hardness measures the force needed to press a steel ball partway into a piece of wood, expressed in pounds-force (lbf). Higher numbers mean greater resistance to denting. It measures dents, not scratches, which depend mostly on the finish. Values for the same species differ between charts, and a difference of under about 100 lbf is effectively a tie.
Using one common chart, hickory is 1,820, hard maple 1,450, white oak 1,360, ash 1,320, red oak 1,290, American black walnut 1,010, American cherry 950 and southern yellow pine 870. Treat these as reference points and not exact guarantees.
| Species | Janka hardness (lbf) | Group |
|---|---|---|
| Hickory | 1,820 | Hard |
| Hard maple | 1,450 | Hard |
| White oak | 1,360 | Hard |
| Ash | 1,320 | Hard |
| Red oak | 1,290 | Standard |
| American black walnut | 1,010 | Standard |
| American cherry | 950 | Soft |
| Southern yellow pine | 870 | Soft |
A rough grouping helps. Woods under 1,000 lbf, such as pine and cherry, will dent and show wear, which some people welcome in a rustic or older home. Woods from about 1,000 to 1,300, such as red oak and walnut, are the everyday choice for most homes. Woods above 1,300, such as white oak, maple and hickory, suit busy households with kids and pets.
Grain affects how wear shows. Open-grained woods like oak and hickory hide small marks better than smooth, tight-grained maple, which shows every mark but takes a clean modern finish. Hickory has strong contrast between light and dark boards, so it is a bolder look than other species.
Color is a matter of taste and of the rest of the house. Red oak has a warm, slightly pink tone, white oak is more neutral and tends toward yellow-brown, maple is pale and fine, walnut is a deep brown and cherry darkens with exposure to light. Take samples home and look at them in your light.
Stain can change color but not hardness. Maple and cherry can look blotchy with some stains, so the species and finish should be chosen together. Finish also affects footing: a very glossy finish can feel slippery in socks, so discuss sheen and slip resistance before finishing. If treads are only part of a larger update, see our stairs and railings service.
Light exposure changes wood over the years. Some species darken or lighten as they age, which is part of why an old stair rarely matches a new one. If you are replacing only a few treads, expect a difference until the new ones settle in, or plan a refinish that covers the whole stair.
Treads are the surface you walk on, and risers are the vertical faces. Many stairs use a hardwood tread with a painted riser, which saves money and gives a classic contrast. Stringers, skirt boards and handrails can be different species from the treads, but color should be intentionally matched or intentionally contrasted rather than almost the same.
Handrails and balusters are touched constantly, so smooth, stable species suit them. Rules for rail height and shape are summarized in our stair railing code guide. Some projects use one species throughout, and others use paint for balusters and stain for treads. Both work when the finish is carried out well.
Wood is a natural material, and two boards of the same species can look quite different. Lumber is sold in grades that describe how much knotting, color variation and mineral streaking is allowed. Clear grades give a uniform look, while rustic or character grades include knots and color swings. For stairs that will be stained, a more uniform grade helps the finish look consistent from tread to tread.
Ask to see a sample finished the way yours will be, in the light of the room. Dry wood looks very different from wood with a clear coat, and stain can shift the color across species. Looking at an unfinished sample and imagining the result is a common source of surprises.
Solid treads can usually be sanded and refinished, which gives a stair a long life. How often depends on traffic and finish. Felt pads on furniture, a mat at the base of the stair and keeping pet nails trimmed all reduce wear. Avoid stair runners or mats that slide, since they create a fall hazard.
Clean with products recommended by the finish manufacturer, and avoid excess water on wood. Slippery stairs are a safety concern, so if treads feel slick, ask a finishing professional about sheen and traction options rather than applying a product on your own.
Solid versus veneered or engineered stair parts is a separate decision. Solid treads can be sanded and refinished more than once. Engineered parts with a hardwood face can be stable and consistent, but refinishing depends on the thickness of the wear layer. Whatever you choose, ask how the tread nosing is formed and fastened, because loose nosings are a common stair complaint.
Species selection also applies to mantels and shelving, where color and grain are on display. Our mantels and built-in shelving page describes how those pieces are planned.
Among common species, hickory rates highest on one chart at 1,820 lbf, followed by hard maple. Hardness is only one factor, so grain and appearance matter too.
Yes. Red oak, at about 1,290 lbf on one chart, is a common everyday choice. It is hard enough for most homes and its open grain hides small marks.
Not necessarily. Pine is softer and will dent, which some people like in rustic or older homes. If you want a crisp, unmarked look, choose a harder species.
No. Stain changes color only. Hardness depends on the species, and scratch resistance depends largely on the finish.
