TV VESA Patterns Explained: How to Check Your TV Before Buying a Wall Mount

VESA is the mounting-hole pattern on the back of a television. It is written as horizontal spacing × vertical spacing in millimetres, for example 200 × 200 or 400 × 300. A wall mount must support your TV’s exact VESA pattern as well as its weight. Size alone is never enough.

How to find your VESA pattern

Remove the TV stand only if the manufacturer’s instructions allow it, then look for four threaded mounting holes on the rear panel. Measure the distance from the centre of the left hole to the centre of the right hole, then from the centre of the top hole to the centre of the bottom hole. Record both measurements in millimetres. Alternatively, search the TV model’s official specification sheet for “VESA mounting interface.”

Common VESA examples

The mount specification must list your pattern or a range that includes it. Do not force a mismatch by drilling new holes in the TV, using makeshift plates or relying on only two screws.

VESA is only one compatibility check

Also verify the TV’s bare weight without its tabletop stand against the mount’s rating. Confirm the wall type and installation method are appropriate, especially for an extending full-motion arm. Consider rear-panel shape, recessed mounting holes, port access and the space needed for cables. A compatible VESA pattern does not automatically mean a mount will suit every wall or room layout.

Choosing the right mount after VESA

Choose a fixed mount for a close, straight-on setup; a tilt mount for a controlled vertical angle; or full motion when viewers genuinely need swivel or extension. Read our fixed, tilt and full-motion comparison before deciding. For concrete-wall planning in Singapore, use the pre-installation checklist.

Take these details before shopping

1. TV make and exact model number
2. VESA width and height in mm
3. TV weight without its stand
4. Wall type and intended mounting position
5. Ports, soundbar and cable-routing needs

With these details ready, you can select a ULTI TV wall mount by verified compatibility rather than guesswork.

How to use this guide for your own setup

Turn the specification sheet into a real compatibility check

Screen size alone does not tell you whether an arm will work. Find the monitor model on its label or manufacturer page, then write down its weight without its original stand, VESA mounting pattern, the position and depth of the VESA recess, and the dimensions of the rear housing. These details affect both the arm’s load range and the physical clearance when the screen is raised, rotated or pulled forward.

Measure the desk as well as the screen

1. Measure desktop thickness at the exact clamp position.
2. Check beneath and behind that point for drawers, cable trays, rear support bars, modesty panels and wall clearance.
3. Measure the available depth. A gas-spring arm needs room to articulate; a portrait screen can need more height and rear clearance than expected.
4. Plan the cable route with the arm at its furthest and highest position. A cable that is taut at one position can pull on a port as the arm moves.

Before you buy

Ask for the supported load range per arm, clamp and grommet requirements, VESA hardware supplied, and whether an adapter is required for your exact monitor. Do not rely on a marketplace title or an image alone: compare the listing details with the model’s official specifications. If anything is unclear, photograph the rear of the monitor and the desk edge, then use ULTI’s monitor arm finder or the monitor-and-desk fit FAQ to work through the fit before ordering.
