The VESA (Video Electronics Standards Association) interface is the distance between the four mounting holes on the back of a TV (shown as 'horizontal distance x vertical distance').
This interface is commonly used to mount screens on wall mounts or stands.
TVs up to 32 inches usually have a VESA of 100x100 mm;
VESA 200x200 is common for TVs up to 55 inches;
TVs larger than 55 inches usually have a VESA of 300x300 or even 400x400;
TVs larger than 65 inches usually have a VESA of 600x400.
Measuring the distance between the (four) horizontal and vertical holes on the back of your TV is the fastest and easiest way to find the VESA size for your TV.
The first distance stated for a VESA interface is always the horizontal distance. The second distance is the vertical distance between the holes.
These two measurements produce the following format: HORIZONTAL x VERTICAL = VESA interface pattern.
VESA 100x100 - The fastening points are 10 cm apart
VESA 200x200 - The fastening points are 20 cm apart
VESA 300x300 - The fastening points are 30 cm apart
VESA 400x200 - The fastening points are horizontally 40 cm and upright 20 cm apart
VESA 400x400 - The fastening points are 40 cm apart
VESA 600x400 - The fastening points are horizontally 60 cm and upright 40 cm apart
