Shiplap vs Tongue and Groove: What’s the Real Difference?

Shiplap and tongue and groove (t&g) are both popular choices for interior and exterior cladding, but the main difference between them is the way they fit together. Shiplap has a groove cut into the top and bottom of each board, allowing them to overlap in a tight, interlocking pattern.

T&g, on the other hand, has a tongue that protrudes from one side of the board and fits snugly into a groove on the other side of the adjacent board. This creates a flush joint with no gaps between the boards.

Shiplap and t&g are both timeless design elements that add character and warmth to any space. Whether you’re aiming for a rustic, coastal, or modern look, the right cladding can make a big difference in achieving your desired aesthetic. But before you choose between shiplap or t&g, it’s important to know the differences between them. In this article, we’ll explore these differences in more detail and help you make an informed decision for your project.

Tongue And Groove: Characteristics And Applications

Tongue and groove (t&g) is a popular building technique that has been around for centuries. It is widely used for creating stable and secure joints that are used in flooring, paneling, and roofing. This technique involves inserting a protruding tongue on the edge of one board into the groove of another, creating a strong and straight joint.

Here are some of the characteristics, materials, and applications of t&g.

T&g boards have a unique interlocking mechanism that ensures a tight, secure fit between boards. The tongue on one board is fitted into the groove of another, which makes the boards fit tightly together. This interlocking mechanism offers excellent stability and durability to any structure.

Additionally, t&g boards do not have gaps between them, which makes them ideal for applications where a smooth surface is necessary.

Name The Most Common Materials Used For Tongue And Groove Boards

T&g boards can be made from various types of wood, including oak, maple, cedar, and pine. These materials offer a wide range of color, style, and texture options. Furthermore, engineered wood products, including mdf, plywood, and particleboard, can also be used to create t&g boards.

  • Beaded: Beaded t&g has a rounded bead on one board’s edge and a matching groove on the opposite edge, creating a charming and classic look.
  • Nickel gap: It is a perfect option for shiplap lovers. A tiny space between two panels gives it a sleek appearance.

T&g is an excellent option for creating sturdy and durable structures. The interlocking mechanism ensures a tight, secure fit between boards, and the use of different materials means it can be adapted to suit various applications.

Compare And Contrast The Characteristics And Applications Of Shiplap And Tongue And Groove

Shiplap and tongue and groove are used for interior wall cladding and flooring and people often confuse the two. However, they are quite different in terms of style, installation, and finishing. Shiplap boards interlock with one another on their sides, creating clean horizontal lines.

Tongue and groove, on the other hand, interlock at their ends. Here are some ways in which they differ:


  • Shiplap boards feature a small gap between them, which is referred to as a reveal.
  • In tongue and groove, there is no gap, and the boards fit snugly against one another.

Interlocking Mechanism

  • Shiplap boards interlock on their sides, forming an overlapping edge that creates a shadow line effect.
  • Tongue and groove boards connect at their ends, creating a continuous, smooth surface without any shadow effect.


  • Shiplap is most commonly made of wood but can also be made from synthetic materials like vinyl, fiber cement and plywood
  • Tongue and groove is commonly made of wood but is also available in pvc or other synthetics and composites.

Explain Why The Confusion Between The Two Occurs

The reason why people often confuse shiplap and tongue and groove is that they are both used for the same purpose, that being wall cladding and flooring. Additionally, shiplap boards are sometimes installed in a tongue and groove fashion, which adds to the confusion.

Also, many homeowners and contractors do not know that there are technical differences between shiplap and tongue and groove. This can lead to incorrectly identifying the material that is in use and may even result in improper installation. Despite these differences, both shiplap and tongue and groove remain popular choices for wall cladding and flooring due to their versatility and aesthetic appeal.


Now that you have a thorough understanding of shiplap and tongue and groove, you can make an informed decision about which option is right for you. Shiplap is a popular choice among homeowners due to its rustic charm and easy installation.

On the other hand, tongue and groove offers a more seamless finish and better insulation properties. It’s also great for high moisture and humidity environments. Keep in mind that these two options differ in terms of appearance, cost, and installation, so take these factors into account before making a final decision.

Ultimately, both shiplap and tongue and groove can add warmth, texture, and character to any room in your home. Whether you prefer a coastal-inspired aesthetic or a modern farmhouse vibe, these two styles of paneling are sure to give your walls an eye-catching look.
