Quick Answer: Shiplap is a type of wood board with a rabbet (notch) cut along each long edge, so boards overlap slightly when installed horizontally. The overlapping edges create a uniform shadow line between each board, giving walls a clean, linear texture. It originated as exterior siding and structural sheathing on barns and homes in the 19th century - today it is used almost entirely for interior accent walls and decorative paneling.
Shiplap became a dominant design trend after being prominently featured on renovation television - but it has been around for well over a century and earns its popularity for good functional and aesthetic reasons. Here is everything you need to know about what it is and how to use it.
What Is the Shiplap Joint?
The defining feature of shiplap is the rabbet - a stepped notch cut along each long edge of the board. When two boards are placed next to each other, the rabbet of one fits over the rabbet of the other, overlapping slightly. This creates:
- A tight, water-resistant joint (why it was used as exterior siding)
- A consistent, uniform gap between boards that creates a shadow line
- A wall surface that is more stable and less prone to gaps opening as wood expands and contracts
The shadow gap - typically 1/8 to 1/4 inch - is what creates the distinctive linear texture that makes shiplap walls so visually appealing.
Shiplap vs. Board and Batten vs. Tongue and Groove
| Style | Joint Type | Look | Orientation |
|---|---|---|---|
| Shiplap | Rabbet overlap | Horizontal lines with consistent shadow gap | Horizontal (most common) or vertical |
| Board and Batten | Flat boards + cover strips | Wide panels with narrow raised strips | Vertical |
| Tongue and Groove | Interlocking tongue and groove | Tight, nearly seamless or with V-groove | Horizontal or vertical |
| Flat Planks | Spaced with gaps (no joint) | Linear with consistent even gaps | Horizontal or vertical |
Where Shiplap Works Best
Shiplap is well-suited for:
- Accent walls: Behind a bed in a bedroom, behind a sofa in a living room, as a fireplace feature wall
- Entryways and mudrooms: Adds character and is easy to wipe clean
- Bathrooms: Works well in half baths; in full baths, use moisture-resistant materials or finish with a quality primer and paint for humidity protection
- Kitchens: Behind open shelving or as a backsplash area alternative (finished with a wipeable paint or sealer)
- Full room installation: All four walls in a bedroom or living room creates a cozy, enveloping feel
How to Install Shiplap
Shiplap installs horizontally over existing drywall using a nail gun or finish nails driven into studs. Start at the bottom with a level base row, use a spacer (or let the rabbet create the natural gap), and work upward row by row. The overlap of the rabbet naturally maintains spacing consistency.

Paint or Stain?
White-painted shiplap is the classic modern farmhouse choice - crisp, clean, and versatile. Natural wood stain shows the grain and adds warmth. Gray-stained shiplap has a driftwood, coastal feel. All work well; the choice depends on the room's palette and the feel you want to create.
