Mounting a 65-inch TV with a full motion bracket is one of the most popular home improvement projects right now. But if you want the mount to sit as close to the wall as possible when retracted, you need an ultra thin profile design. And before you even pick a mount, you need to understand your wall’s stud spacing, because that determines which models will actually work for your installation.
This guide covers everything you need to know about ultra thin full motion mounts for 65-inch TVs, with a detailed look at 16-inch versus 24-inch stud spacing and how it affects your options.
What Makes a Full Motion Mount “Ultra Thin”?
A full motion TV wall mount lets you extend, swivel, and tilt your TV away from the wall. When you push the TV back, it folds against the wall surface. The distance between the wall and the back of the TV in this retracted position is called the profile.
Standard full motion mounts typically have a retracted profile between 60mm and 100mm. An ultra thin full motion mount aims to reduce that to under 50mm, sometimes as low as 27-35mm. The thinner the profile, the closer your TV sits to the wall when you are not adjusting it, giving a cleaner, more built-in appearance.
Achieving a thin profile requires precise engineering. The arm joints need to fold flat, and the wall plate needs to be as slim as possible while still distributing the load across the mounting points. This is where manufacturer quality really matters.
Why Stud Spacing Matters: 16-Inch vs 24-Inch Centers
In North American construction, wall studs are typically spaced either 16 inches or 24 inches apart, measured from center to center. This spacing determines where you have solid wood or metal framing behind the drywall to anchor heavy loads.
16-inch stud spacing is the most common in residential construction. Most rooms in houses built after 1970 use 16-inch centers for load-bearing and standard interior walls. The closer spacing gives you more anchor points and generally makes TV mount installation easier, since the mount’s wall plate holes are more likely to align with two or more studs.
24-inch stud spacing is common in non-load-bearing interior walls, certain commercial buildings, and some newer energy-efficient construction methods. With studs farther apart, you have fewer anchor points per horizontal span. This means your mount’s wall plate needs to be wide enough to reach from one stud to the next, or you need to use a mounting plate or toggle bolt solution for the gaps.
For a 65-inch TV, which typically weighs between 35 and 55 pounds, mounting into at least two studs is essential for safety. A mount rated for 16-inch stud spacing will work on walls with studs at that interval. But if your studs are 24 inches apart, you need a mount with a wall plate that spans at least 24 inches, or you need to add a support board between the studs.
How to Determine Your Stud Spacing
Before ordering a mount, verify your stud spacing:
Use a stud finder. Run an electronic stud finder horizontally along the wall at the height where you plan to mount the TV. Mark each stud location with painter’s tape. Measure the distance between marks.
Check from an electrical outlet. Electrical outlets in the US are almost always attached to a stud on one side. Find an outlet on the same wall, locate the stud next to it, then measure 16 inches in either direction to find the next stud.
Tap the wall. As a quick check, knock on the wall and listen. A hollow sound means you are between studs. A solid, dull sound means you are on or near a stud. This method is less precise but can confirm what your stud finder tells you.
Top Ultra Thin Full Motion Mounts for 65-Inch TVs
Here are models worth considering, depending on your stud spacing and weight requirements:
ThunderTech Pros 506-44
The ThunderTech Pros 506-44 supports TVs from 32 to 65 inches with a maximum VESA pattern of 400x400mm and a weight capacity of 110 lbs (50 kg). The retracted profile is just 62mm, which is thinner than most full motion competitors. It extends out to 357mm for comfortable angle adjustment. The 506-44 works with standard 16-inch stud spacing and includes integrated cable management along the arm.
This model strikes a solid balance between thin profile and heavy load capacity. At 110 lbs, it handles virtually any 65-inch TV on the market with a comfortable safety margin.
ThunderTech Pros 689
For slightly larger setups or if you want more extension range, the ThunderTech Pros 689 covers 32 to 80-inch TVs, supports up to VESA 600×400, and holds 100 lbs (45.5 kg). The profile is 60mm retracted, extending to 403mm. The wider VESA support means it also works for TVs with wider mounting hole patterns, which some 65-inch models have.
ThunderTech Pros 120-84
If your 65-inch TV is on the heavier side, or if you plan to upgrade to a larger screen later, the ThunderTech Pros 120-84 is the heavy-duty option. It supports 37 to 95-inch TVs up to 220 lbs (100 kg) with VESA patterns from 100×100 to 800×400. The retracted profile is 82mm, and it extends up to 1,229mm. This mount is designed for wider wall plates, making it compatible with both 16-inch and 24-inch stud spacing.
What About Ultra Thin Fixed Mounts?
If your priority is getting the absolute thinnest profile and you do not need the swivel and extension features, a fixed mount like the ThunderTech Pros CF64 achieves a 27mm profile. Fixed mounts are inherently thinner because there are no moving parts to fold. However, you lose the ability to adjust the viewing angle after installation.
Installation Guide: Ultra Thin Mount on 16-Inch Stud Walls
Step 1: Locate two adjacent studs using a stud finder. Mark the center of each stud vertically at your desired TV height.
Step 2: Hold the wall plate against the wall and align the mounting holes with the stud centers. Use a level to ensure the plate is perfectly horizontal.
Step 3: Pre-drill pilot holes into each stud through the wall plate holes. Use a drill bit slightly smaller than the lag bolts included with your mount.
Step 4: Drive the lag bolts through the plate into the studs. Tighten them firmly but do not overtighten, as this can crack the stud or strip the hole.
Step 5: Attach the TV brackets to the back of your TV using the provided bolts and spacers. Match the bolt pattern to your TV’s VESA holes.
Step 6: Hang the TV on the wall plate, route your cables through the mount’s built-in cable management channels, and test all range of motion.
Installation Considerations for 24-Inch Stud Walls
With 24-inch stud spacing, you have two main options:
Option A: Use a mount with a wide enough wall plate. The ThunderTech Pros 120-84, for example, has a wall plate that spans well beyond 24 inches, so you can anchor into two studs even at wider spacing.
Option B: Install a plywood backing board. Cut a piece of 3/4-inch plywood to span at least two studs (minimum 28 inches wide). Anchor the plywood into both studs with heavy-duty lag screws, then mount the TV bracket anywhere on the plywood. This method lets you use any mount regardless of its wall plate width, and it distributes the load across a larger area.
Never rely solely on drywall anchors for a 65-inch TV, even toggle bolts. The weight and leverage of a fully extended full motion arm can pull standard anchors out of drywall over time.
Weight Capacity: How Much Margin Do You Need?
A 65-inch TV typically weighs between 35 and 55 pounds, depending on the brand and model. LED and OLED panels are lighter; older LCD panels with thicker backlights are heavier.
As a safety rule, choose a mount rated for at least 1.5 times your TV’s weight. So for a 50-pound TV, look for a mount rated at 75 lbs or higher. This gives you margin for:
– The added leverage when the arm is fully extended
– Minor vibrations from nearby foot traffic or closing doors
– The weight of cables and any attached accessories like a soundbar mount
The ThunderTech Pros 506-44 at 110 lbs capacity gives you over 2x margin for most 65-inch TVs, making it one of the safest options in its size class.
Frequently Asked Questions
Can I mount a 65-inch TV on one stud?
It is not recommended. A single stud can technically hold the weight, but the sideways torque from a full motion arm, especially when extended, can loosen a single-stud mount over time. Always use at least two anchor points.
Does VESA pattern affect how thin the mount profile is?
Indirectly, yes. TVs with wider VESA patterns (like 600×400) often have the mounting holes set farther from the back panel edge. The mount’s arm connector needs to accommodate this, which can add a few millimeters to the profile. Models like the 689 handle larger VESA patterns while keeping the profile at 60mm.
What if my stud spacing is not exactly 16 or 24 inches?
Older homes and some commercial buildings may have irregular stud spacing. In these cases, the plywood backing board method is the safest approach. It gives you anchor flexibility regardless of where the studs fall.
Are ultra thin full motion mounts less sturdy than thicker ones?
Not necessarily. The profile thickness is about the folding geometry of the arm, not the structural integrity. A well-engineered thin mount like the 506-44 with proper steel construction and 110 lb rating is just as secure as a bulkier alternative. The key is material quality and load testing, not thickness alone.
Conclusion
For a 65-inch TV, the ideal ultra thin full motion mount depends on your wall construction. On standard 16-inch stud walls, the ThunderTech Pros 506-44 delivers a 62mm profile with 110 lbs capacity, integrated cable routing, and straightforward two-stud installation. For 24-inch stud spacing, the 120-84 provides the wider wall plate coverage you need along with heavy-duty capacity for future-proofing.
Check your studs first, pick a mount with adequate weight margin, and install it properly. The result is a 65-inch TV that sits nearly flush against the wall when retracted and swings out smoothly when you need to adjust the angle.
