What inch size is my TV? Inch size guide
The world of consumer electronics offers a variety of monitor and television sizes that meet the different needs and applications of customers. The most common sizes are between 10 and 105 inches. A list of the sizes with the corresponding diagonals and dimensions (16:9) can be found a little further down in the text.
Inch to Centimeter Conversion Chart for Monitor/TV Sizes
The size of TVs and monitors is often given in inches, which describes the diagonal size of the screen. Since many countries use the metric system, it is useful to know how to convert these measurements to centimeters (cm). This can be particularly helpful in understanding the size of the TV in relation to the space available or in choosing the right model.
Basic Conversion Formula
1 inch = 2.54 cm
This constant allows for easy conversion from inches to centimeters.
How can I easily determine the inch size of my TV?
If you do not know the inch size of your screen, you can easily find out.
- Measure the screen from bottom left to top right in cm (only the glass, not the casing).
- Divide the result by 2.54 (1 inch = 2.54 cm).
- Round the result and you have the inch size of the screen.
The inch size is an important variable that you need when buying a TV mount. Other important factors are, for example, the (existing) VESA mount and the weight of the TV.

Importance of Conversion for TV Mounts
For example, if you want to buy a TV with a screen diagonal of 55 inches, this is equivalent to 139.70 cm. This conversion will help you better estimate the space the TV will take up and ensure that it fits well in your living room or intended location.
Knowing the diagonal screen size in centimeters will help you choose the right size mount. Here are some important points to consider:
- Compatibility: Make sure the mount can support the weight and size of the TV. A mount that is too small or too weak could be unsafe.
- Mounting points: Many mounts use VESA (Video Electronics Standards Association) standards, which are also given in millimeters. It is important to know the VESA dimensions of the TV and check that they fit the mount.
- Distance from the wall: Some mounts allow a small distance from the wall, while others are swivel or tilt and require more distance. The size of the TV in centimeters will help determine the ideal distance.
