Builders across the U.S., Canada, and Australia are rethinking trim and moulding choices as minimalist design dominates. In 2026, bigger baseboards and sleek casings are more than aesthetic—they’re essential for modern builds.

These oversized baseboards not only protect walls and floors but also provide architectural weight that complements open-concept layouts and high ceilings.

But are these trends purely style-driven, or are they influencing construction standards and buyer expectations? Let’s explore what’s driving the 2026 baseboard trends, how builders are adapting, and which baseboard and casing styles are dominating projects across North America and Australia.

What Are the Trim Trends for 2026?

In 2026, trim and moulding are stepping into the spotlight—not just as finishing touches, but as defining features of interior spaces. Builders are opting for wider trim profiles that are clean, square-edged, and minimalist. Think 3.5 to 5.5 inches for casings and even broader baseboards for a grounded, architectural look.

This movement aligns with modern baseboard styles like Scandinavian, Japandi, and transitional interiors, all of which are trending in new builds and renovations alike.

Painted in matte whites or soft neutrals, trims are now designed to frame the space, not compete with it. Builders are being asked to install trim that enhances natural light and works with airy, open layouts—a significant shift from the dark, decorative finishes of the past.

Is Contrast Trim in Style for 2026?

Yes—and it’s a growing design feature. Contrast trim involves painting or staining baseboards and casings in a tone that stands out from the walls. This might mean charcoal trims on ivory walls or navy mouldings on soft greys.

For builders, contrast trim provides an easy way to offer personality without complicating construction. These high-impact visuals work best with modern baseboard trim options like square edge or eased edge profiles.

Expect to see this trend in custom home builds, multi-unit rentals, and remodels where the goal is modern but cozy.

Are Ornate Mouldings Going Out of Style?

Absolutely. Builders are ditching decorative beveling and intricate scrollwork in favor of flat stock and streamlined trims. Traditional crown and colonial profiles are being replaced by:

• Square and eased-edge profiles
• Craftsman-style casings
• Flush baseboard-to-wall transitions

This not only saves time and materials during installation but also reflects the shift toward cleaner architecture and sustainable design.

Still, some clients are asking for subtle elegance. That’s where picture frame molding is making a comeback—used selectively on walls for accenting, not in the entire trim package.

What Size Baseboards Are Trending in 2026?

Homeowners and designers are going big. The average modern baseboard in 2025 ranges from 5 to 7 inches tall, often paired with high ceilings and open-concept floor plans.

Here’s why bigger baseboards are trending:

• They make rooms feel more grounded and substantial.
• They enhance modern interiors with architectural weight.
• They work well with minimalist trims and square openings.

For builders, installing larger trim doesn’t require more skill—it just requires different sourcing and a little planning. It’s also an excellent upsell opportunity for added value in renovations.

Baseboard Size & Proportion Guide

Choosing the right baseboard height is crucial to maintain balance and proportion in any room. A general rule of thumb is approximately 1/2″ to 3/4″ of baseboard per foot of ceiling height. This ensures your trim complements the space without looking too small or overpowering.

Here’s a quick reference table to help you choose the perfect baseboard height for your room:

What Are Modern Baseboard Styles Builders Should Know?

Here are the top modern baseboard styles builders should have in their catalog:

• Square Edge: Flat and bold, this is the go-to in ultra-modern homes.
• Eased Edge Baseboard: With its slightly rounded top edge, this style is everywhere—from single-family homes to condos.
• Step Baseboard: A soft nod to traditional moulding but much cleaner and more contemporary.
• Flush Baseboards: High-end and minimal, these sit seamlessly against drywall for a shadowless effect.

Pairing these with modern flooring—like wide plank oak or polished concrete—helps achieve the complete look clients want in 2026.

How Does Eased Edge Baseboard Compare to Traditional Trim?

Eased edge baseboard is becoming a default in 2026 for a good reason. It delivers the same height and visual impact as colonial trim but with less visual noise.

For builders, the benefits are clear:

• It’s easy to cut, install, and paint.
• Works with modern or transitional doors and windows.
• Offers a cleaner, more hygienic finish with fewer dust-catching ridges.

It also fits well with modern color palettes, especially in white, gray, or greige tones—making it a safe and stylish choice for most builds.

Where Does Picture Frame Molding Fit Into 2026 Designs?

Once seen as old-school, picture frame molding is gaining fresh relevance in 2026. It’s now used as an accent feature, not a full trim package.

Builders are using it in:

• Dining rooms, to add dimension without clutter.
• Hallways, for visual interest.
• Home offices, as an elegant backdrop for bookshelves or desks.

Most designers are painting the picture frame molding the same color as the wall, creating a tone-on-tone texture that feels both modern and intentional.

This is a low-cost, high-impact detail that builders can offer in renovations or staging projects.
