Shiplap vs. Tongue and Groove Wood Paneling: Differences, Benefits and More

A thicker and more substantial type of wood veneer, shiplap and tongue-and-groove paneling has made a strong comeback in recent years. Thanks to the rise of modern farmhouse design, these wood finishes have shed their old associations with outdated '70s interiors. Instead of looking cheap or overused, today's paneling adds clean lines, natural texture, and a sense of warmth and depth to walls and ceilings.

Not sure what sets shiplap apart from tongue-and-groove wood paneling? You’re not alone. In this guide, we'll walk you through the differences, benefits, and best-use scenarios for each—so you can choose the right paneling for any room or outdoor space.

Wood Paneling: A Modern Farmhouse Trend

So what makes this once-outdated wall treatment feel fresh again? It all comes down to presentation. Modern designers and homeowners, think Magnolia's Joanna Gaines, have brought new life to paneling by changing how it’s styled and installed.

In most modern applications, shiplap and tongue-and-groove paneling are painted white or in soft neutrals rather than left as plain woodgrain. Instead of functioning as simple trim, they create a barn-inspired backdrop that instantly brightens a space. 

They’re also being used in more creative ways—extending across entire ceilings, open-concept living spaces, or as full accent walls, rather than just half-walls or chair rails.

One of the most noticeable updates? Orientation. Today’s shiplap and tongue-and-groove paneling is often installed horizontally, adding visual width and drawing the eye across the space. It’s common to see horizontal shiplap behind kitchen tables, on fireplace walls, or paired with built-in shelving.

One thing that often gets overlooked in the wood paneling trend? The actual type of paneling used. While shiplap is the most recognized term, it’s just one of many options including beadboard, board and batten, and wainscoting. Of all the styles, tongue-and-groove is the closest match, and it’s easy to mistake the two—leading to the wrong choice for a project.

The Differences in Shiplap vs. Tongue and Groove Wood Paneling

Shiplap and tongue-and-groove paneling may look similar once installed, but the difference lies in the profile of each plank. 

Shiplap planks are cut with a small L-shaped notch, called a rabbet joint, along their edge. These notches allow the boards to slightly overlap, creating a stepped effect as they stack along the wall or ceiling. Some styles also include a beveled edge to soften the seams for a more finished look.

Tongue-and-groove paneling features a tongue on one side and a matching groove on the other. The tongue fits snugly into the groove of the next board, creating a strong, interlocking seam. While some tongue-and-groove boards may include a slight bevel, most have square edges that deliver a clean, uniform finish—tighter than what you’ll typically get with shiplap.

Shiplap vs. Tongue and Groove: Which Do You Choose?

Unsure whether to go with shiplap or tongue-and-groove for your project? While they may look similar, choosing without understanding the differences could lead to visual and structural mistakes.

So how do you choose? Below, we’ve broken down practical tips, advantages, and installation insights to help you make the right call for your space.

The Ease of Installation

Need a quicker install to finish your project on time? Shiplap paneling tends to be easier and faster to install than tongue-and-groove. Because the boards overlap with a single rabbet joint, they simply slide into place without much adjustment. Tongue-and-groove, by contrast, has two interlocking sides that require more precision.

With shiplap, once the boards are in position, you can nail directly through the overlapping edge to secure them. Tongue-and-groove panels need to be fastened through the tongue itself, which requires more careful placement. If speed and ease are your priorities, shiplap is the better option.

The Paneling Materials  

Wood is the most common material used for both shiplap and tongue-and-groove paneling. If you plan to paint or finish the surface, affordable woods like pine, and even plywood, are popular choices.

If you prefer to leave the wood natural, consider a higher-quality species like cedar or basswood. A clear sealer will protect the surface while showcasing the wood’s grain and natural beauty. Choose a species that looks good on its own without paint.

Van Dyke’s offers unfinished shiplap crafted from solid basswood hardwood, perfect for customizing your space. Each plank is whitewashed on one side and left raw on the other, so you can choose the finish that works best for your project. No two boards are exactly alike. Eeach features unique natural characteristics like mineral streaks, knots, and visible grain patterns. These authentic details bring rustic warmth to your design. Available by the piece, this shiplap is great for smaller DIY projects such as accent walls, cabinet faces, islands, or door paneling—ideal for capturing that clean, rustic modern farmhouse style.

Shop Unfinished Shiplap

So, besides wood, what other kinds of materials can shiplap and tongue and groove planks be made from? While most wood paneling projects are for interior spaces, you can find other materials intended for outdoor and exterior applications, too. However, you can still get creative with them if you like. From fiber cement to vinyl and metal, there are several other material options.  

Climate Considerations

Both shiplap and tongue-and-groove paneling can be used indoors and out—from cozy interior spaces to sheds, barns, and other exterior structures. But the environment where you’re installing the panels plays a big role in how well each style performs over time. Because these are natural wood materials, it’s important to consider your local climate—especially for outdoor installations—before deciding between the two styles. In wet climates like the Pacific Northwest, shiplap’s overlapping profile naturally sheds water, making it better suited for moisture-prone areas. Tongue-and-groove’s interlocking seams can trap moisture between boards, increasing the risk of warping or rot over time. In hot, dry climate,s like parts of the Southwest, shiplap handles shrinkage better. The overlapping edges disguise minor gaps that may appear as the wood contracts.

In colder regions like the Northeast, tongue-and-groove provides better insulation. Its tight, interlocking fit helps keep warm air in and cold drafts out—making it a smart pick for homes with long winters. This tighter seal can also help improve energy efficiency, especially in areas with extreme temperature swings.

Vertical vs. Horizontal Applications and Designs

Tongue-and-groove paneling can be installed either vertically or horizontally, depending on the look you’re after. Horizontal installation is ideal for visually widening a space, while vertical boards can emphasize height. For exterior use, tongue-and-groove panels lay flush against the wall, forming a tighter seal that helps prevent moisture from seeping in.

Shiplap requires more care in installation, especially in humid or wet environments. While it can be a DIY project, professional installation is recommended for moisture-prone areas like bathrooms or exterior walls in rainy regions.

Affordability

Shiplap is typically more affordable than tongue-and-groove, thanks to its simpler profile and easier installation. Labor costs may be lower, especially for DIYers. However, final pricing depends on material type, room size, and even regional rates.

If you're handling installation yourself, shiplap is more forgiving. Tongue-and-groove requires more precision, so hiring a pro may be worth the investment to ensure a seamless finish.

To estimate how much unfinished shiplap you'll need for your project, follow these basic steps::

1. Measure your space: Start with length × height (or width for ceilings). Example: a 50-square-foot wall.
2. Find the square footage per board: Our unfinished shiplap measures 5" wide × 92" long, with about 3.19 square feet of usable coverage once the overlap is accounted for.
3. Calculate how many boards you need: Divide your wall's square footage by the square footage per board. 

Here’s an example:

50 sq. ft. / 3.19 sq. ft. = 15.7 boards

Plan for overage: Always order a few extra boards to cover cuts, errors, or replacements down the line. In this case, round up to at least 16 boards. 

So, Shiplap or Tongue and Groove?

Now that you know the key differences, it’s time to choose the paneling that best fits your project. For a decorative interior accent—like a kitchen, hallway, or entry wall—shiplap is often the go-to. For exterior builds or spaces that require extra insulation, tongue-and-groove may be the better choice.

Both styles offer unique advantages. Consider your location, design goals, and budget—and enjoy the process of bringing your space to life.

Frequently Asked Questions About Shiplap Paneling and Tongue and Groove Boards

Q: What is the difference between shiplap paneling and tongue and groove boards?

A: Shiplap paneling uses a single rabbet joint that creates an overlap between boards. Tongue and groove boards use an interlocking tongue on one side and a groove on the opposite side. Shiplap creates visible shadow lines and installs quickly. Tongue and groove creates a tighter, smoother finish that handles seasonal movement more effectively.

Q: Is shiplap easier to install than tongue and groove?

A: Yes. Most homeowners find shiplap paneling easier to install because the overlap allows for small alignment adjustments. Tongue and groove boards require careful fitting, and installers often nail through the tongue to keep fasteners hidden. This creates a clean finish but adds time to the project.

Q: Which option works better for bathrooms or moisture-heavy areas?

A: Shiplap paneling can perform well in bathrooms if it is installed correctly, sealed, and painted with a moisture-resistant finish. Tongue and groove boards can trap water inside the joint if moisture gets behind the wall. For high-humidity spaces, proper ventilation and careful installation matter more than the specific style.

Q: Can you install shiplap paneling vertically?

A: Yes. Shiplap paneling works in vertical and horizontal layouts. Horizontal shiplap creates longer visual lines, while vertical shiplap can make a room feel taller. Both approaches look clean and modern when installed carefully.

Q: Is tongue and groove good for exterior siding?

A: Tongue and groove boards can be used on exterior walls when the installation is protected from direct moisture. The tight joint helps keep out drafts and cold air, which makes it a good choice for insulated builds. In very wet climates, many installers prefer shiplap because the overlap sheds water more effectively.

Q: Which option is more affordable?

A: Shiplap paneling is usually more affordable because the profile is simpler and installation takes less labor. Tongue and groove boards often cost more due to the interlocking joint and the extra time needed for fitting each board.

Q: How thick are shiplap boards?

A: Shiplap paneling is commonly sold in thicknesses between 1/2 inch and 3/4 inch. The exact size depends on the manufacturer and the material. Always check the profile measurements before planning your installation.

Q: Do tongue and groove boards need to be painted or sealed?

A: It is recommended. Even if you choose to leave the wood natural, sealing the boards protects against moisture and seasonal movement. Painted finishes work well too, especially in high-traffic or high-humidity areas.

Q: Can you mix shiplap and tongue and groove in the same home?

A: Yes. Many homeowners use shiplap paneling for feature walls and tongue and groove boards for ceilings or exterior areas. The styles complement each other and create visual interest without looking mismatched.

Q: Which one should I choose for a DIY project?

A: Shiplap paneling is the easiest option for most DIY installers. It aligns quickly and allows for simple face-nailing. Tongue and groove boards are still manageable, but they require more precision and a bit more patience.
