The VESA Mounting Standard explained
The VESA Interface Standard defines the distance in millimeters between the four mounting holes on the back of a TV (distance horizontally x vertically). VESA is a standard used for TV wall mounts and wall mounting systems, adapted by most TV brands. Common VESA sizes are 200 x 200, 400 x 400 and 600 x 400 depending on the screen size of your TV.
Where can I find my VESA size?
Horizontal distance is 400 millimetres and vertical distance is 300 millimetres. The required VESA size in this situation is 400x300.
Vesa in summary
To sum up, VESA is a standard adopted by all important television manufacturers. It is the distance between the mounting holes in the back of the TV in millimeters. Whether a TV wall mount is fixed, tilt able, turn able or swiveling, the VESA mounting size is always the same: horizontal x vertical distance in mm.
