TV size: convert inches to centimeters

Until the nineties, in the houses probably there were only one device with a screen: the Tv. Moreover, those who owned one were interested more in what the screen projected than in the object itself. Consumers had no experience, and therefore no preferences, between one TV and another: the choice was between a “large one” for the living room and a “small one” for the kitchen.

In the last twenty years, however, the technology has brought into our lives an increasing number of devices with screens: computers, smartphones, tablets, even watches.

At the same time, the forerunner of these screen devices with screen, the television, has evolved its technology, dimensions and design. Today a TV buyer is on average very informed about the differences between one device and another. Often his choice is affected or even affects the design of the spaces of the house.


The fact that the screens entered our everyday life carried huge changes to our everyday life. However, there is an element, linked to the origins of TV, that has survived every evolution of the screens: the habit of representing the size of the screens with their diagonal expressed in inches. Over time everyone, from the industry professional to the housewife, to the boy who buys his first mobile phone, have acquired the ability to guess the real size of a screen from its measure in inches.

How many of the consumers who go to an electronics store – with the intention of buying a 6-inch smartphone, a 13 or 17-inch computer, or a 65-inch TV – are aware or interested to the fact that one inch is equivalent to 2.54 centimeters or that the inches measure the diagonal of the screen?


In most cases, guessing the size of a TV is an enough – along with its price – to guide the choice between one model and another. However, there are situations in which the client or the professional who studying the rooms of the house of a customer needs to know the exact measurements of the TV in width and height. An example could be the installation of a TV between two windows, in a niche, or the installation of a motorized TV lift.

Conversion chart

That’s why we have created a conversion table that allows to convert the diagonal inches of a TV into its height and width in centimeters. Our goal is to help the professional during the design phase or for the final customer about to buy a TV.

It’s important to stress that this table refers to TVs with an aspect ratio of 16:9, and the measures here contained are very generic: for more specific data, we advice you to consult the technical data sheet provided by the manufacturer.
