How to Choose the Right Drywall Thickness for Commercial Space

To ensure quality, durability, and safety when installing drywall in commercial spaces, it’s crucial to select the proper thickness. It can be confusing to determine which drywall thickness is best for your particular needs with so many options available. We’ll give you a thorough explanation of how to select the appropriate drywall thickness for your commercial space in this article.

What Is Drywall Thickness?

The depth of the drywall sheet is referred to as the drywall thickness. The most popular sizes for drywall are 1/2 inch and 5/8 inch, with a thickness range of 1/4 inch to 1 inch.

Why Does Drywall Thickness Matter?

Your commercial space’s strength, durability, and soundproofing capabilities are significantly influenced by the thickness of the drywall. The wrong thickness selection can result in a number of problems, such as structural instability, inadequate insulation, and increased noise levels.

How to Choose the Right Drywall Thickness

Here are some factors to consider when selecting the right drywall thickness for your commercial space:

1. Building Codes and Regulations

It’s crucial to review your local building codes and ordinances before choosing the appropriate drywall thickness. For fire and safety reasons, these codes will specify the minimum thickness requirements. In some areas of your commercial space, thicker drywall may be necessary because it is generally more fire-resistant.

2. Soundproofing Needs

Thick drywall is typically advised if soundproofing is needed for your commercial space. A quieter workplace can be created with thicker drywall by reducing noise transfer between rooms.

3. Structural Stability

Thickner drywall might be required to ensure structural stability if your commercial space is in a busy area or gets a lot of use. Thicker drywall can offer more support and guard against wear-and-tear damage.

4. Moisture and Humidity

It might be necessary to use thicker drywall if the moisture and humidity levels in your commercial space are particularly high. In general, thicker drywall is more moisture resistant and can stop the growth of mold and mildew.

Drywall Thickness Options

Now that we’ve discussed the factors to consider when selecting the right drywall thickness, let’s take a closer look at the different options available.

1. 1/4 inch Drywall

The thinnest option is 1/4 inch drywall, which is typically used for curved walls, arches, and other specialized applications. Due to its weak construction and short lifespan, it is not advised for use with standard walls.

2. 3/8 inch Drywall

Although slightly thicker at 3/8 inch, drywall is still not advised for standard walls due to its poor durability and soundproofing qualities.

3. 1/2 inch Drywall

The most typical drywall thickness for standard walls and ceilings in commercial spaces is 1/2 inch. It is suitable for the majority of applications and has good strength, soundproofing, and insulation qualities.

4. 5/8 inch Drywall

A thicker choice that offers greater strength, durability, and soundproofing properties is 5/8 inch drywall. For high traffic areas, specialized applications, and to satisfy building code requirements, it is typically advised.

5. 3/4 inch Drywall

The thickest option is 3/4 inch drywall, which is typically only used for specialized purposes like soundproofing or to meet particular building code requirements.


To ensure quality, durability, and safety in your commercial space, choosing the appropriate drywall thickness is essential. You can decide which drywall thickness is ideal for your particular needs by taking into account elements like building codes, soundproofing requirements, structural stability, and moisture and humidity levels. Keep in mind that thicker drywall generally offers better soundproofing and insulation qualities and is more durable, while thinner drywall is best used in specialized applications. You can make sure that your commercial space is secure, cozy, and useful by taking the time to choose the appropriate drywall thickness.
