DIY TV Support: How to Build Safe, Stable TV Stands and Mounts

When you build a DIY TV support, a custom structure designed to hold a television safely and securely. Also known as TV stand, it TV mount, it needs to handle weight, balance, and safety—especially if you’re mounting a 70-inch screen or placing it where kids or pets are around. A poorly built support can lead to tipping, damage, or worse. You don’t need to hire a pro if you know what to look for in materials, height, and anchoring.

Most people focus on how the TV looks, not how it stays put. But the DIY TV support is more than just a shelf—it’s a load-bearing structure. Think about the weight: a 70-inch TV can weigh over 50 pounds. Add a soundbar, cables, and decorative items, and you’re pushing 70 pounds or more. That’s why wood thickness, bracket strength, and wall anchors matter. A TV stand, a freestanding piece of furniture designed to hold a television made from particleboard will sag over time. A TV mount, a fixed or adjustable bracket attached to a wall to hold a television needs to be anchored into studs, not drywall alone. Even if your TV looks small, the leverage from a long stand or an angled mount creates serious torque.

Height is another hidden issue. A 70-inch TV should sit so the center of the screen is at eye level when seated—usually around 42 inches off the floor. If your stand is too low, you’re straining your neck. Too high, and you’re looking up at an awkward angle. That’s why many DIYers end up building adjustable stands or using risers. And if you’re mounting on the wall, you need to account for cable management, ventilation, and access to ports. A clean-looking setup isn’t just about style—it’s about function.

You’ll find plenty of posts here that cover real-world fixes: how to stop a TV from sliding, what wood thickness actually holds weight, how to match a stand to a recliner sofa, and why some mounts fail after a year. These aren’t theoretical guides—they’re solutions people used in their homes, with tools they already owned. Whether you’re building a simple console, reinforcing a shelf, or installing a full wall mount, the advice here is practical, tested, and focused on what actually works.
