Choosing Between Shiplap and Nickel Gap Siding

Shiplap and nickel gap are two of the most popular siding and paneling styles in modern design, each offering its own distinct character. Choosing between them isn’t always easy, both profiles offer unique aesthetics and can bring beautiful, timeless character to any project.

Whether you’re updating an interior space or finishing the exterior of your home, understanding the nuances between shiplap and nickel gap will help you make the right choice, especially when working with sustainable, durable alternatives like ACRE by Modern Mill. In this blog, we’ll break down the differences between these two styles, explore the best uses for each, and guide you toward the best fit for your next build or renovation.

What is Shiplap Siding?

Shiplap siding is one of the most sought-after profiles in modern design, commonly used for both interior and exterior applications. Characterized by its tight and secure fitting boards, shiplap creates a clean, streamlined appearance that blends rustic charm with contemporary appeal. Shiplap has become a key feature in today’s design-forward projects.

What makes shiplap unique is its tongue-and-groove construction, where each board fits into the next, creating a secure seal while still allowing for a slight reveal. This distinctive design adds texture and depth to walls, ceilings, and siding. While often associated with farmhouse-style interiors, shiplap’s versatility allows it to complement a variety of aesthetics, from coastal retreats to modern urban spaces.

What is Nickel Gap Siding?

Nickel gap siding is a modern take on traditional wooden paneling, characterized by a small, consistent gap between the boards. This narrow gap, typically about the thickness of a nickel, creates a clean, refined appearance. Unlike shiplap, which features tighter edges, nickel gap boards are spaced with a reveal that enhances depth while maintaining a sleek, contemporary look. It’s commonly used for both interior and exterior applications, offering a slightly more polished finish while still providing a touch of rustic charm.

Nickel gap siding can be used in a variety of settings, from modern homes to stylish interior accent walls. It’s simple yet impactful design complements various architectural styles.

Choosing Between Shiplap & Nickel Gap

Choosing between shiplap and nickel gap siding ultimately depends on your design goals, the space you’re working with, and the overall style of your project. Shiplap offers a traditional, rustic feel with its overlapping boards and wider reveals, making it a natural fit for farmhouse, cottage, or coastal-inspired spaces. While nickel gap has more narrow, consistent spacing and cleaner lines, bringing a modern, polished look that pairs well with contemporary or minimalist aesthetics.

When deciding, also consider whether the application is interior or exterior. Both profiles can work in either setting, but each offers a slightly different effect depending on the setting. Ultimately, your decision should align with the visual tone you want to create, as well as how the profile complements other materials and design elements in the space.
