Question: 1 / 400

What is the typical thickness of drywall used in most interior walls?

1/4 inch

1/2 inch

The typical thickness of drywall used in most interior walls is 1/2 inch. This size is standard for residential construction in non-load-bearing walls, providing a good balance of strength, weight, and affordability. It is versatile and widely available, making it the go-to choice for general applications in interior wall construction.

Using 1/2 inch drywall allows for sufficient coverage and sound insulation while being manageable for handling and installation. Thicker options, like 3/4 inch and 1 inch, are more commonly reserved for specific situations, such as soundproofing or fire-rating requirements, rather than typical interior wall applications. Conversely, 1/4 inch drywall is often used for repair work, curved surfaces, or applications where minimal weight is needed, rather than standard wall construction. Therefore, 1/2 inch stands out as the industry standard for most interior walls.
