Best Wood for Stairs: Treads, Risers and Handrails

A staircase is used thousands of times a year, often in socks, shoes and bare feet, carrying people, furniture and shopping. It must be strong, safe, quiet and good-looking for decades. Choosing the best wood for stairs means looking at hardness, stability, slip resistance and finish, and thinking about each part separately: treads, risers, strings, newel posts and handrails.

In this guide we compare the hardwoods stair makers use most, with a focus on African species we supply from Central Africa at Global Timber Trade Hub. We also cover sizes, construction, finishes and how to buy stair timber in volume.

In short

Stair treads need hard, stable wood that resists wear and dents.
Wenge, moabi, doussie and sapele are excellent tread woods.
Iroko and sapele are popular all-rounders for treads, strings and handrails.
Treads are usually 32–45 mm thick, made from solid boards or laminated blanks.
Use a durable, slip-conscious finish on treads.
Order kiln-dried stock at about 8–10% moisture content.

What makes a good stair wood?

Hardness: resists dents from heels and dropped objects.
Wear resistance: the front edge of treads, the nosing, takes the most wear.
Stability: treads must stay flat and not creak or split.
Strength: treads span between strings and must not deflect.
Appearance: the staircase is often a focal point.
Workability: handrails and newels need smooth shaping and finishing.

Treads: where hardness matters

Treads take almost all the wear. For busy homes and commercial buildings, choose hard species such as wenge, moabi or doussie. Sapele is an excellent value option, harder than many classic mahoganies.

Risers and strings

Risers and strings take less wear, so you can use a slightly softer or more economical species, or a painted finish. Many stairs combine hardwood treads with painted risers for a classic look. Strings must be strong and straight; sapele, sipo and iroko are good choices.

Handrails and newel posts

Handrails need wood that shapes cleanly and feels smooth in the hand. Sapele, moabi, African mahogany and afrormosia are popular. Newel posts are often made from laminated blanks for stability. See African mahogany and afrormosia.

Tread sizes and construction

Thickness: commonly 32–45 mm for treads, depending on span and building rules.
Width: domestic treads are often 250–300 mm deep; commercial stairs may differ.
Solid or laminated: wide treads are usually glued from narrower staves to stay flat.
Nosing: the front edge is rounded or profiled for comfort and safety.

Always follow local building regulations for rise, going, headroom and handrail height.

Slip resistance

Smooth, glossy treads can be slippery, especially in socks. Choose a satin or matt finish, consider anti-slip inserts or grooves near the nosing on public stairs, and avoid wax polishes. For outdoor steps, use durable species such as iroko or doussie with grooved surfaces and good drainage.

Finishes for stairs

Hard-wax oil: natural feel, easy to repair, good slip behaviour.
Floor lacquer: durable, easy to clean, available with anti-slip additives.
Paint: for risers and strings in classic designs.

Moisture content

Order stair timber kiln dried to about 8–10% for heated homes. Let blanks acclimatise before machining. Wet timber will shrink, open joints and creak. See kiln dried vs air dried lumber.

Matching stairs with floors

Many homeowners want the staircase to match the hardwood floor. If the floor is already laid, choose the same species and finish for the treads, and ask for boards of similar colour. If both are new, order floor and stair timber from the same batch so colours match. Contrasting combinations also work well: dark wenge treads with white risers, or a golden movingui floor with darker moabi treads and handrails. See our guide to tropical hardwood flooring.

Cladding an existing staircase

Many renovations clad an old softwood or concrete staircase with new hardwood treads and risers rather than building a new stair. Cladding treads are usually 20–30 mm thick and glued and screwed to the existing structure. This approach saves cost and disruption. Stable species such as doussie, sapele and moabi work well, as they must stay flat when fixed over another material.

Commercial and public stairs

Stairs in offices, shops, hotels and public buildings face heavy traffic. Choose the hardest species you can, thicker treads where spans are long, and a hard-wearing floor lacquer with anti-slip properties. Consider metal or contrasting nosing inserts to improve visibility and grip. Check fire and accessibility rules, which may set requirements for materials, contrast and handrails.

How much timber does a staircase need?

A straight domestic staircase with 13 treads of 900 × 280 × 40 mm contains about 0.13 m³ of finished tread wood. Allowing for lamination, machining and defects, you need roughly 0.2 m³ of rough kiln-dried stock for the treads. Add strings, risers, newels and handrails, and a full hardwood staircase typically needs 0.4–0.6 m³ of rough timber. Stair manufacturers producing many stairs buy by the container and plan cutting to minimise waste.

Buying stair timber as a manufacturer

Stair makers usually buy kiln-dried FAS boards in 32, 40 and 52 mm thicknesses for treads and strings, plus thicker stock for newels. Pre-laminated tread blanks can save machining time. Keeping one or two main species in stock, with consistent colour, makes production and customer matching easier. We supply regular shipments to stair manufacturers on a fixed specification.

Lead times

Kiln-dried sapele, iroko and movingui can usually be prepared in 4–8 weeks before loading. Wenge and moabi depend on current stock; doussie and afrormosia need CITES permits, so allow extra time.

Spiral, winder and floating stairs

Not every staircase is a straight flight. Spiral and winder stairs use tapered treads that are wide at one end and narrow at the other. These are cut from wide laminated blanks, so stability matters even more. Floating or cantilever stairs, where treads appear to project from the wall with no visible support, need thick, stiff treads, often 60–80 mm, fixed to hidden steel brackets. For these designs, dense species such as doussie, moabi and wenge give the stiffness and solid feel people expect. A thin or soft tread on a floating stair will flex and feel unsafe, even if it is structurally sound.

Noise and creaking

Creaking stairs are one of the most common complaints in homes. Most creaks come from movement between treads, risers and strings, not from the wood itself. Using dry, stable timber, tight housings, glue blocks and screws instead of nails reduces movement. Wood that was too wet when fitted will shrink and leave gaps that creak. Ordering timber at the correct moisture content and letting it acclimatise is the cheapest way to avoid this problem.

Colour change over time

All the woods in this guide change colour with light. Sapele and moabi deepen to a richer red-brown. Iroko and afrormosia darken from yellow-brown to a deeper golden brown. Movingui mellows from bright yellow to a warm gold. Wenge can lighten slightly in strong sun. Areas covered by stair runners or rugs will stay lighter, so leave stairs uncovered for the first few months if you plan to use a runner later. See our African hardwood prices guide for more on each species and its cost.

Outdoor steps

External steps for gardens, decks and entrances face rain and sun. Use naturally durable species such as iroko, doussie, tali or azobe. Leave small gaps for drainage, cut grooves or fit anti-slip strips, and avoid ground contact for the treads. Interior species such as wenge and movingui are not the best choice outside. Our guide to the best hardwood for decking covers outdoor durability in more detail.

Our honest advice

For most homes, sapele or moabi treads with matching handrails give a beautiful, durable staircase at a sensible price. For a dramatic modern look, wenge treads with white risers are hard to beat. For wide, premium treads, doussie’s stability is worth the cost. Whatever you choose, laminate wide treads, choose a slip-conscious finish and follow your local building rules.

Ordering checklist

Species and grade, usually FAS or select for visible treads and handrails.
Thicknesses for treads, strings, risers and newels.
Minimum widths and lengths, so treads can be cut with little waste.
Moisture content, normally 8–10% for indoor stairs.
Colour matching needs, if the stair must match a floor or joinery.
Quantity, delivery port and whether you want FOB or CIF pricing.

Common mistakes

Soft wood for busy treads: dents and wear show quickly.
Glossy finishes on treads: they can be slippery.
Wide solid treads without lamination: they cup and split.
Ignoring building regulations: check rise, going and handrail rules.
