When it comes to finishing your staircase, the details matter—and few details are as important as the stair moulding. More than just decorative trim, stair moulding serves a functional purpose, protecting edges and surfaces while helping to define the architectural character of your space. One of the most critical decisions when selecting stair moulding is choosing the right type of wood. With so many options available, how do you strike the perfect balance between durability, style, and budget?
In this in-depth guide, we’ll explore the best types of wood for stair moulding, examining the benefits and drawbacks of each, so you can make a confident and lasting choice.
Why Wood Type Matters for Stair Moulding
Staircases are among the highest-traffic areas in any home, which means the moulding surrounding them must be especially strong and resilient. Here’s why your choice of wood plays a pivotal role:
-
Durability: Different woods have different hardness levels, affecting resistance to dents, scratches, and wear.
-
Stability: High-quality wood resists warping and expansion with seasonal humidity changes.
-
Aesthetic: Wood species vary in grain pattern, colour, and texture—impacting how well they match your décor.
-
Finish Compatibility: Some woods accept stain or paint better than others, which matters for final appearance.
1. Oak – The Gold Standard for Strength and Longevity
Why It’s Great
Oak is one of the most popular choices for stair moulding—and for good reason. Whether you opt for red oak or white oak, you’ll benefit from a hardwood that’s incredibly durable, versatile, and readily available.
Key Features
-
Janka Hardness: ~1,290 (Red Oak), ~1,360 (White Oak)
-
Grain: Prominent, open grain; easily visible
-
Finish: Takes stain very well; available in many pre-finished options
Best For:
-
High-traffic staircases
-
Traditional and transitional homes
-
Projects where durability is a top priority
Considerations:
-
Can be heavy and harder to work with for DIYers
-
Prominent grain may not suit minimalist designs
2. Maple – Sleek, Smooth, and Modern
Why It’s Great
Maple wood is a fantastic choice if you’re aiming for a smooth, uniform look. Its subtle grain and natural light colour make it a favorite for modern staircases or painted finishes.
Key Features
-
Janka Hardness: ~1,450
-
Grain: Fine and consistent
-
Finish: Accepts paint well; can be tricky to stain due to density
Best For:
-
Contemporary and minimalist homes
-
Painted or light-toned moulding
-
Areas where a smooth finish is preferred
Considerations:
-
Uneven stain absorption can lead to blotchiness
-
Slightly more expensive than oak
3. Poplar – Cost-Effective and Paint-Friendly
Why It’s Great
If you’re planning to paint your stair moulding, poplar is one of the best and most budget-friendly options. It’s a softer hardwood, which makes it easy to cut and install.
Key Features
-
Janka Hardness: ~540
-
Grain: Straight and uniform
-
Finish: Takes paint beautifully; not ideal for staining
Best For:
-
Painted moulding projects
-

Low- to medium-traffic stairs
Considerations:
-
Not as durable as oak or maple
-
Dents and scratches more easily
4. Walnut – Luxury and Sophistication
Why It’s Great
Walnut is a premium hardwood prized for its rich, dark tones and striking grain patterns. It adds instant luxury to any stairway, making it perfect for high-end interiors.
Key Features
-
Janka Hardness: ~1,010
-
Grain: Wavy, bold grain with occasional knots
-
Finish: Excellent for dark stains and natural finishes
Best For:
-
Luxury homes
-
High-contrast interior design schemes

Statement staircases
Considerations:

One of the more expensive options

5. Cherry – Elegant and Timeless
Why It’s Great
Cherry wood offers a warm, reddish-brown hue that deepens over time. It’s a classic choice for moulding in both traditional and craftsman-style homes.
Key Features
-
Janka Hardness: ~950
-
Grain: Smooth with subtle figuring
-
Finish: Deepens naturally; takes stain well
Best For:
-
Classic or historic homes
-
Rich, warm-toned interiors
-
Stained trim work
Considerations:
-
Tends to darken with age (can be a pro or con)
-
Pricier than basic hardwoods
6. Birch – Durable and Understated
Why It’s Great
Birch is a strong, straight-grained wood that offers a slightly more budget-conscious alternative to maple. It’s tough and takes finishes well, making it a strong contender for stair moulding.
Key Features
-
Janka Hardness: ~1,260
-
Grain: Straight, subtle
-
Finish: Good for both stain and paint
Best For:
-
Versatile design schemes
-
High-traffic staircases
-
Budget-conscious projects with a desire for durability
Considerations:
-
Prone to blotchy staining (use a conditioner first)
-
Less common in pre-finished trim pieces
7. Ash – Strong and Striking
Why It’s Great
Ash combines the best of both worlds—it’s strong like oak but has a more dramatic grain pattern. Its pale colour makes it easy to stain, but it’s often used naturally for its visual appeal.
Key Features
-
Janka Hardness: ~1,320
-
Grain: Bold, straight grain
-
Finish: Takes stain well, especially for rustic looks
Best For:
-
Rustic and industrial interiors

Homes looking for a standout wood grain
-
Durable, everyday use
Considerations:
-
Can be harder to find in trim profiles
-
More expensive than poplar or pine
Honorable Mentions: Other Wood Types for Niche Applications
– Pine: Inexpensive and easy to work with, but soft and dent-prone. Good for painted trim in low-traffic areas.
– MDF (Medium Density Fiberboard): Not technically wood, but common for painted trim. Inexpensive, smooth, but vulnerable to moisture and damage.
– Reclaimed Wood: Great for eco-conscious or rustic projects. Unique character but can be inconsistent in quality.
