How Thick Does a Plywood Floor Have to Be?

Plywood flooring is a popular option for homeowners due to its cost-effectiveness, versatility, and durability. However, determining the ideal thickness for your plywood floor can be crucial to ensure long-lasting performance. In this blog, we will explore the factors that influence the thickness of plywood flooring, the recommended thickness range for different applications, and some key considerations to keep in mind.

Understanding the Influencing Factors

Subfloor Type and Condition

The condition of your subfloor plays a vital role in determining plywood thickness. If you have an uneven or damaged subfloor, opting for thicker plywood can help level the surface, improving stability and reducing the potential for squeaking or movement.

Support Span

The distance between joists or underlying support structures affects the required plywood thickness. A wider span necessitates thicker plywood to prevent sagging and maintain structural integrity. To determine the optimal thickness, consult a building professional or refer to industry standards based on your specific project.

Recommended Thickness Ranges for Plywood Flooring

Underlayment and Floating Applications

For underlayment purposes, such as preparing a smooth surface for vinyl or carpet installation, the typical recommended thickness ranges from 1/4-inch (6mm) to 1/2-inch (12mm) plywood. This thinner plywood is cost-effective and easy to work with, providing adequate support for the top flooring layer.

A slightly thicker plywood is preferred in floating floor installations, where the plywood flooring is not directly attached to the subfloor. A 1/2-inch (12mm) to 5/8-inch (15mm) thickness range is commonly used to ensure proper stability and prevent flexing.

Subfloor and Structural Plywood

For traditional plywood flooring installations, where the plywood is directly attached to the subfloor, the recommended thickness typically ranges from 5/8-inch (15mm) to 3/4-inch (19mm) plywood. This thickness range provides sufficient support, minimizing the risk of flexing or squeaking.

Considerations for Your Plywood Flooring Decision

Climate and Environmental Factors

If you live in an area with significant humidity or temperature fluctuations, choosing a plywood thickness that can withstand the environmental conditions is crucial. Choosing thicker plywood can add stability, preventing warping or moisture-related issues.

Heavy Traffic and Activity Levels

A thicker plywood with increased load-bearing capacity is recommended in high-traffic areas or rooms with heavy furniture. By opting for a higher thickness, you can ensure long-lasting durability and prevent premature wear or damage.

Acoustic Considerations

If sound transmission is a concern, such as in multi-level homes or apartments, consider using thicker plywood or incorporating additional soundproofing materials to minimize noise transfer.
