This article will guide you on how much weight your drywall can support and what to consider before mounting anything.
Whether you plan to hang a picture or mount a TV, you might wonder whether it is safe to hang this. Knowing the weight limits is essential to prevent damage and ensure safety.
Drywall alone can hold about 1.5 pounds to 2 pounds per square foot. With certain additional equipment like anchors, the weight capacity can be increased up to 150 pounds.
Different types of Drywall and their Strengths
Understanding the type of drywall in your home is important, as it can help you determine the maximum weight it can safely support. There are several types of drywall, each with its own load-bearing capabilities.
Regular Drywall (Whiteboard):
- Thickness: Standard thickness, typically 1/2 inch.
- Special Features: Most commonly used in residential spaces.
- Strength: Provides standard load-bearing capability but is less durable than other types.
Type X Drywall:
- Thickness: Thicker than regular drywall, often 5/8 inch.
- Special Features: Contains special fibers for more durability.
- Strength: More durable and capable of supporting more weight than regular drywall.
Moisture-Resistant Drywall (Green/Blue Board):
- Thickness: Similar to regular drywall, typically 1/2 inch.
- Special Features: Designed to resist moisture and prevent mold growth.
- Strength: Less capable of supporting weight compared to both regular and Type X drywall
Weight Capacity in Different Home Areas
Above Doors and Windows
The drywall in these areas is less capable of handling heavy loads due to structural limitations. These wall parts often need more direct support from studs, which can cause the drywall to crack if too much weight is applied.
My Experience: I thought of having an extra TV in my bedroom too. My bedroom is small, and there is no place to add a couch. I decided to mount my TV above the door for a better view. This way my bed and TV are in the same line. But the handyman who came to mount the TV suggested this is not the right place for TV. After rearranging furniture, we added a chair and found a better place to mount my TV.
In Bathrooms or Garages
These areas might have moisture-resistant drywall, which has a slightly different composition. It supports less weight than regular drywall as it is primarily designed to resist mold and water damage rather than bear heavy loads.
Anchors for Additional Load Capacity
Anchors are designed to distribute the weight of an object more evenly across a larger surface area. This allows you to hang heavier items without damaging the wall. The more anchors you use, the greater the weight the drywall can support.
There are different types of anchors available. Check out our article on the different types of drywall anchors to find the one that suits your needs.

| Type of Anchor | Load Capacity ( per pair ) |
| Plastic Ribbed Anchors | Up to 10 pounds |
| Threaded Drywall Anchors | Up to 25 pounds |
| Hollow-Wall Anchors | Up to 30 pounds |
| Expansion Anchors | Up to 100 pounds |
| Self-Drilling Anchors | Up to 150 pounds |
Alternatives to Anchors: Drywall Backing
Drywall backing adds extra support to your walls, especially when you want to mount heavy items without relying solely on anchors. Installing backing behind your drywall can make nails and screws stronger by providing a solid surface for them to grip.
What is Drywall Backing?
Drywall backing means adding a piece of wood between the wall studs before putting up the drywall. This wood provides a strong base for nails, screws, or heavy items, making the wall more capable of holding more weight.
How Does it Work?
When you attach nails or screws to a wall with drywall backing, they go through the drywall and into the wood behind it. This makes the wall much stronger and allows it to hold heavier items than if the nails or screws were just in the drywall alone.
