VESA mounts explained: How to match your TV's mounting pattern
Engadget explains how to identify a TV's VESA mounting pattern, noting that matching the hole pattern alone is not enough and that weight limits and hardware also matter.
The VESA pattern describes the spacing between the threaded mounting holes on the back of a TV, typically arranged in a square or rectangle. The first number is the horizontal distance and the second is the vertical distance. For example, a TV with a 400×200 pattern has holes spaced 400 millimeters apart horizontally and 200 millimeters apart vertically. A 200×200 pattern measures 200 millimeters in both directions. These numbers do not indicate screen size or resolution; larger TVs often use larger patterns, but checking the exact model is more reliable than guessing by screen size.
To find the VESA pattern, look up the TV model in its manual or on the manufacturer's support page, where the wall-mount or VESA specification is usually listed. If the spec is unavailable, measure from the center of one mounting hole to the center of the corresponding hole horizontally and vertically, and write the result as horizontal × vertical in millimeters.
Even if the hole pattern matches, the mount must also be able to hold the TV's weight. Compare the mount's maximum load with the weight of the TV. Additionally, VESA compatibility says nothing about the screws or how the bracket attaches to the wall, so follow both the TV manufacturer's instructions for the required mounting screws and the mount manufacturer's instructions for attachment.
