Is Tongue and Groove Plywood More Expensive?

Yes, tongue and groove plywood is usually slightly more expensive than standard plywood sheets.
The higher price comes from its special edge design, where one side has a “tongue” and the other a matching “groove.” This allows the panels to fit tightly together, creating a stronger, smoother, and more stable surface — perfect for floors, walls, and ceilings.

Reasons for the higher cost:

1. Extra machining process: Cutting precise tongue and groove joints requires additional production steps and equipment.

2. Better fit and stability: The interlocking system reduces movement, squeaks, and gaps, improving installation quality.

3. Reduced need for fasteners: Because panels lock together, they often require fewer screws or nails.

4. Higher performance: Provides better load distribution, especially for subfloors and structural applications.

   
   

   

Price difference

Depending on the thickness and grade, tongue and groove plywood typically costs 5–15% more than square-edge plywood. However, the long-term benefits — such as easier installation, stronger joints, and less maintenance — make it a cost-effective option for many construction projects.
