Hang TV Drywall Anchors: Your Ultimate No-Fail Guide
Hanging a brand new television on drywall can feel like a disaster waiting to happen. You have a heavy, expensive piece of electronics and a wall made of compressed gypsum powder. The fear of a catastrophic crash is real, and it keeps many from even attempting the project.
The core of the problem lies in the material itself. Drywall is relatively soft and has very little structural integrity on its own. A simple screw has almost nothing to grip, which is why it can be pulled out with minimal force, taking your TV with it.

Why You Can’t Always Rely on Wall Studs
In a perfect world, you would mount your television directly into the wooden studs behind the drywall. Studs provide a solid, secure anchor point that can easily support the weight. However, wall studs are typically spaced 16 or 24 inches apart, and their locations rarely line up perfectly with where you want your TV to be.
This is a common dilemma in home theater setup. The ideal viewing height and horizontal position often fall in the empty cavity between two studs. For many, the question of should TV be centered on wall takes precedence, forcing them to find a solution for mounting on hollow drywall.
Understanding Shear vs. Pull-Out Force
When you hang a TV, the anchors must resist two types of forces. Shear force is the downward pull of gravity, trying to slice the screw through the drywall. Pull-out force (or tensile force) is the anchor being pulled straight out from the wall, and this is where most failures occur.
An articulating or full-motion mount dramatically increases the pull-out force when the TV is extended. The leverage created by the arm acts like a crowbar, prying the anchors out of the wall. This is the most critical factor to understand when selecting your anchors; what works for a flat mount may fail spectacularly with an articulating one.
Choosing the Right Drywall Anchor: Your Key to Success
The market is flooded with dozens of anchor types, but only a select few are appropriate for the heavy, dynamic load of a television. Using the wrong hardware is the number one cause of mounting failures. Do not use standard plastic conical anchors or simple self-drilling anchors for a TV.
These lighter-duty anchors are designed for static loads like picture frames and are completely inadequate for a television, especially one on an articulating mount. You must use an anchor that distributes the load across a wider area of the drywall behind the wall’s surface.
The Gold Standard: Toggle Bolts
For mounting a TV on drywall, toggle bolts are the undisputed champion. A toggle bolt consists of a screw and a spring-loaded wing mechanism. You drill a hole, fold the wings, insert them through the hole, and they spring open flat against the back of the drywall.
As you tighten the screw, the wing pulls tight against the back of the wall, creating a secure clamp that distributes the weight over a large surface area. Modern strap toggles or snap toggles are an evolution of this design, making installation even easier by pre-installing the toggle and using a plastic guide.
A Viable Alternative: Molly Bolts (Sleeve Anchors)
Molly bolts, also known as sleeve-type anchors, are another strong option. When you tighten the screw on a molly bolt, the metal sleeve behind the drywall expands and compresses, creating a wide, load-bearing flange. They are very secure but can be trickier to install perfectly than a toggle bolt.
The main drawback is that they require a very precise hole size and can be difficult to remove. However, for a permanent installation like a TV mount, they provide excellent holding power when installed correctly.
Drywall Anchor Comparison for TV Mounting
Understanding the capabilities of each anchor type is crucial. The weight ratings listed are often for shear force in ideal conditions; the pull-out strength, especially with an articulating mount, is the more important consideration.
| Anchor Type | How It Works | Pros | Cons |
|---|---|---|---|
| Strap/Snap Toggle Bolt | A metal bar is inserted through the wall and pulls flat against the back, distributing the load widely. | Extremely high load capacity; Best choice for TVs; Easy to install. | Requires a relatively large hole; Cannot be easily removed. |
| Molly Bolt (Sleeve Anchor) | A metal sleeve expands behind the drywall to create a secure flange. | Very strong and reliable; Permanent installation. | Requires a precise hole size; Can be difficult to install correctly. |
| Heavy-Duty Self-Drilling Anchor | A wide-threaded anchor screws directly into the drywall. | Easy and fast to install; No pre-drilling needed. | NOT recommended for TVs; Lower pull-out strength; Can damage drywall. |
| Plastic Conical Anchor | A plastic sleeve expands as a screw is driven into it. | Good for very light items (under 10 lbs). | Absolutely unsafe for TVs; Very low holding power; Prone to failure. |
Step-by-Step Guide to Hanging Your TV with Drywall Anchors
With the right anchors in hand, the installation process is straightforward. Precision and patience are key. Do not rush these steps.
1. Plan and Measure
First, determine the exact location for your TV. Use painter’s tape to mark the outline of the TV on the wall to visualize its placement. Place the mounting bracket against the wall within this outline and use a level to ensure it is perfectly straight. Use a pencil to mark the drilling locations through the holes in the bracket.
2. Drill the Pilot Holes
Choose a drill bit that matches the size specified by your anchor’s manufacturer. Drilling a clean hole is important; sometimes, you may find that drywall crumbles when you drill, which can be a sign of old or damaged board. If this happens, you may need to shift your location slightly.
3. Install the Anchors
Follow the specific instructions for your chosen anchors. For snap toggles, you will insert the metal toggle bar through the hole, pull the strap to set it against the back of the wall, and then slide the plastic cap into place before snapping off the excess strap. For molly bolts, you will gently tap the entire anchor into the hole until it is flush.
4. Secure the TV Mount
With your anchors in place, position the TV mount over them. Insert the provided bolts through the mount and into the anchors. Begin tightening the bolts by hand first to ensure they are not cross-threaded. Then, use a screwdriver or wrench to tighten them until the mount is snug and secure against the wall. Do not over-tighten, as this can damage the drywall.
5. Hang and Test the TV
Attach the corresponding mounting plate to the back of your TV. With the help of another person, carefully lift the TV and hook it onto the wall mount according to the manufacturer’s instructions. Once it’s in place, gently apply some pressure to the TV and mount to ensure everything is solid and there is no movement or creaking from the wall.
Mistakes That Lead to Disaster
Avoiding common pitfalls is just as important as following the correct steps. Be aware of these frequent errors to ensure a secure installation.
Using an Underrated Mount
Ensure your TV mount is rated for the size and weight of your television. A mount that is too small or flimsy will put excessive stress on the anchors and the wall, even if the anchors themselves are strong. Always choose a mount rated well above your TV’s actual weight.
Ignoring Wall Material Differences
This guide is specifically for standard drywall. If you suspect you have different walls, the rules change. For instance, finding the right anchors for lath and plaster walls requires a completely different approach, as the material is more brittle and has hidden wooden lath strips.
Forgetting the Weight of the Mount
When calculating the total load, many people forget to add the weight of the mount itself to the weight of the TV. A heavy-duty articulating mount can weigh 20-30 lbs on its own. Always combine the weight of the TV and the mount before selecting your anchors to ensure you are well within their safety limits.
Frequently Asked Questions
Can you hang a TV on drywall without studs?
Yes, it is possible to hang a TV on drywall without studs by using the correct drywall anchors. Heavy-duty drywall anchors like toggle bolts or molly bolts are designed to securely fasten a TV mount to a hollow wall.
What kind of drywall anchors should I use for a TV?
For hanging a TV, it is best to use heavy-duty drywall anchors such as toggle bolts (including snaptoggles) or molly bolts. These types of anchors expand behind the drywall to create a strong hold capable of supporting the weight of a television.
How much weight can drywall anchors hold?
The weight capacity of drywall anchors varies by type and size. Some heavy-duty toggle bolts can hold up to 100 pounds or more in 1/2-inch drywall, while other types of anchors may support less weight. It’s crucial to check the weight of your TV and the load capacity of the specific anchors you choose.
Are drywall anchors safe for all types of TV mounts?
Drywall anchors are safest when used with fixed or tilting TV mounts. It is generally not recommended to use drywall anchors with full-motion or articulating mounts, as the movement can put extra stress on the anchors and the drywall, increasing the risk of failure.
How do I install drywall anchors for a TV mount?
Installation varies by anchor type, but generally involves drilling a pilot hole, inserting the anchor into the hole, and then securing it. For toggle bolts, the wings collapse to go through the hole and then open up behind the drywall. Molly bolts are inserted into the hole and the screw is tightened to expand the sleeve behind the drywall.
