Small bedrooms are kind of a puzzle. You've got closets, windows, and a door or two eating up every wall, and somehow you still need to figure out where to put a TV that you can actually see from the bed. That was the situation in my guest room slash home office. I spent a lot of time trying to come up with something that worked. Ceiling mount, some kind of drop down mechanism from the attic, I looked at all of it. Everything seemed way more complicated than it needed to be.
What I ended up doing was mounting the TV directly on the sliding hollow core closet doors. I'll be honest, I wasn't totally sure it would hold up long term. But that was 2017. It's now 2026 and the TV is still up there, the door still slides fine, and nothing has moved.
Here's exactly how I did it, and the one mistake most people make that'll send the whole thing crashing down.
- The door skin is hollow. You need a solid wood backing board cut to the full door width
- Screws go through the board and into the solid wood frame that runs along each side of the door
- Stick with a smaller lighter TV. 32" to 40" is the sweet spot for a door mount
- Leave slack in all your cables so the door can still slide open and closed
- I've been running this same setup for 9 years on the same door and it works
About Hollow Core Doors
Hollow core doors are built around a thin wood frame with a veneer skin glued over each face. The space in between is usually filled with cardboard honeycomb to keep the veneer from flexing inward. That fill material and the thin skin aren't structural at all. They'll pull right through if you try to hang any real weight off them. If you just drove screws straight into the center of the door and tried to hang a TV mount off them, they'd rip through the skin eventually. The door would be garbage and your TV would be on the floor.
What is solid is the perimeter frame. There's typically about a 1-1/2" wide piece of wood running along both vertical edges and across the top and bottom of the door. That's your anchor point. The whole trick here is to attach a backing board that spans the full width of the door so you can drive screws into those solid side rails on both edges. The board bridges across the hollow center and transfers all the load into the frame where the wood can actually handle it.
Disclaimer
This mounting technique isn't the most ideal. Even though most TV mount manufacturers provide a warranty against damage to the TV if the mount fails, none of the ones I contacted will honor it for this type of installation. You need to make sure the door is in good condition and the track hardware is in good shape before you do this.
I also wouldn't recommend this for a young child's room. Kids climb, they pull on things, they hang off furniture, and a TV on a sliding door introduces a risk I wouldn't be comfortable with in that environment. For an adult bedroom, a guest room, or a home office where the door doesn't get thrown around constantly, it's a different story. That's exactly what I did. My setup is in a guest room slash home office and it doesn't get messed with all that often. Nine years in and it's been completely fine. But you understand that if you do this you do it at your own risk.
Choosing the Right TV Size for a Door Mount
Since the door's going to be sliding around with the TV on it, you want to keep the TV size reasonable. An LED TV with a width that's less than the width of the door is going to work best. A 32" is ideal, 40" still works fine. Going wider than the door starts to look awkward and puts a lot more stress on the track rollers every time you open and close it.

Mounting a TV to a Hollow Core Door
Measure the door and cut the backing board
First thing you need is a piece of lumber cut to the exact width of your hollow core sliding door. Mine was 36". The board needs to span the full width so your screws can reach the solid wood frame on both sides. The width of the board itself should be wide enough that your mount screws land at least a couple inches from the edges. You don't want them right on the edge of the board where it could split. A 5/4 x 6 worked well for my mount. You could go with framing lumber but something like an S4S pine board is going to look a lot nicer. If you don't have a saw, most home centers will rip it to length for you.
Position the board and mark where your screws will go
Hold the board up against the door at the height where you want the TV to end up. For watching from a bed you generally want the center of the screen somewhere around 42" to 48" off the floor. Adjust for your specific situation. With the board held in position, mark your screw locations on the board so they fall within about 1-1/2" of each side edge where the solid door frame is. I used 5 screws per side spaced roughly 1" apart vertically. If you're using a wider board I'd add more screws.
Drill pilot holes and countersinks in the board
Drill pilot holes all the way through the board at each marked location. Then run your countersink bit at each hole so the screw heads will sit flush with or slightly below the board face. Don't skip the countersink. That's how you split boards when you drive screws near the edge. Takes an extra 30 seconds per hole and saves you the headache.
Transfer the marks to the door and drill pilot holes
Use the board as a template and transfer the hole locations to the door. Hold the board exactly where it'll end up and use a pencil through the holes to mark the door. Then drill shallow pilot holes into the door frame. You're just getting the screw started, not drilling all the way through. Before you drive any screws, probe around to make sure you're actually hitting solid wood and not hollow space. You can usually tell pretty quick when the bit changes resistance.
Attach the board to the door
Set the board back in position, check that it's level, and drive the #8 x 2-1/2" screws through the board and into the door frame. You want at least 1" of thread biting into the frame without the tip coming out the back side. Snug them down firm but don't go crazy. You're driving into a door frame, not a ledger board. If you're using a thicker piece of lumber you might need to go up to 3" screws to make sure you're getting enough bite into the frame.
Paint or stain the board to match the door
This is optional but I'd defintely do it. Take the time to sand it smooth, prime it, and paint or stain it to match your door before you put the mount on. A raw pine board on a white hollow core door looks exactly like what it is, an afterthought. This step takes an extra hour and makes the whole thing look like it belongs there.
Attach the TV mount to the board
Now you'll mount the TV mount to the board you just attached to the door. Check your mount instructions for the mounting hole spacing and pre-drill pilot holes at those locations. Use your level and take your time here. A crooked mount is really annoying to fix once the TV is hanging on it. Drive the lag screws that came with the mount until it's snug and doesn't move. I was able to use the lag screws that came with my mount because they weren't so long that they'd go through the board and into the door.
Let it sit before you hang the TV
Before you put the TV on, give the whole assembly some time, at least a day, and test it. Pull on the mount, push on it, put some real force on it and make sure nothing shifts. When I first did this I was pretty nervous about it right up until I loaded it up and it didn't move at all. That's when I felt good about hanging the TV. Follow the instructions for your particular mount to get the TV attached.
Hang the TV and deal with the cables
Cable management is going to be a bit of an issue with this setup. The key thing is to leave enough slack in all your cables so the door can still slide fully open and closed in both directions. If your cables are tight they'll get stressed at the door edge every time it moves and eventually something's going to fail or get pinched. Route the cables up and along the top of the door casing using adhesive cord clips or cable ties to keep them out of the way when you're accessing the closet. Leave a generous loop of cable right at the point where the door edge meets the casing. That's your stress relief.
Tips for Mounting a TV on a Closet Door
Looking back at the original version of this post from 2017, a few things I'd change or do different if I was starting over:
- Get a tilting mount, not a flat one. Being able to angle the screen down a few degrees makes a real difference when you're watching from a bed and the TV is sitting at or above eye level. The price difference between a flat mount and a tilt mount is minimal and it's worth it.
- Keep the TV at 40" or under. The weight stays manageable for the door track hardware and the TV's width stays within the door panel. Go bigger and you're adding a lot more stress to the rollers every time the door moves, plus the TV starts hanging past the sides of the door which looks weird.
- Plan your cable management before you mount anything. I ended up going back and adding adhesive cord clips along the top of the door casing to keep the HDMI and power cables from hanging loose. Cheap fix but it's easier to do it before the TV is up. Most importantly, leave a loose loop of cable right at the point where the door edge meets the casing. That's where cables get stressed and fray over time if you're not careful.
This isn't the most ideal solution but it's been working out really well for me. The doors still function fine for accessing the closet and even with sliding the doors, tilting and turning the TV it's been very secure over the years.
FAQ
Yes, but not directly into the door skin. The veneer and cardboard honeycomb fill aren't strong enough. What works is attaching a solid wood backing board that spans the full width of the door, then driving screws through that board into the solid wood frame that runs along both edges of the door. The board spreads the load across both frame rails instead of relying on the hollow center. This is what I've been doing for 9 years on my own door without a problem.
Done right with a reasonably sized TV it's safe. I've had mine up for 9 years and it hasn't moved. The things that matter most are the condition of the door track hardware and how heavy the TV is. TV mount manufacturers won't warranty this kind of installation so you're taking that on yourself. I wouldn't do it with a large heavy TV or in a room where kids are climbing on things, but for a smaller screen in a guest room or office it works fine.
32" to 40" is the sweet spot. The width stays within the door panel, the weight's manageable for the track hardware, and the viewing angle from a bed is comfortable at that size. I've had a 32" on mine since 2017. Once you start going bigger the weight adds up fast and the TV starts hanging past the edges of the door on both sides.
Yes, and that's honestly one of the better parts of this setup. The door slides normally. You need to manage your cables so nothing snags when it moves, but I access my closet regularly with the TV mounted and it's never been an issue. Just leave a loose loop of cable at the door edge and route the rest along the top casing with some cord clips.
A sliding closet door is the best option I've found when every wall is taken up by windows, doors, or furniture. The TV faces the bed, the closet still works, and you're not blocking anything. Other things people try are ceiling mounts (complicated and expensive), corner mounts (awkward viewing angle), or over-the-door hangers (usually not rated for a real TV). The backing board method is the most solid of all those options and the one I'd actually recommend.
The backing board approach works on any hollow core sliding door, including bypass closet doors, some wardrobe doors, and so on. Barn doors are usually solid wood all the way through so you can skip the backing board and mount directly into the door as long as the wood is thick enough. Just make sure wherever you're screwing into is actually solid and not veneer over air.
#8 x 2-1/2" coarse thread bugle head wood screws are what I used. Long enough to get at least 1" of bite into the door frame after going through the board, but not so long they poke out the back. If you're using a thicker board step up to 3" screws. Stick with coarse thread. It grabs wood a lot better than fine thread for this kind of application.
