Inches to Centimeters Conversion

To convert inches to centimeters (in to cm) can be helpful to reduce frustrating errors or even potential mistakes, even in simple tasks, such as buying a television or a tv lift mechanism. 

Until the nineties, houses probably had just one device with a screen: the TV. 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, 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 devices with screen, the television, has evolved its technology, dimensions and design.

Today a TV buyer is quite informed on the differences between one device and another. Often his choice is affected or even affects the design of the spaces of the house.

On the one hand, the purchases of electronic material has become an online experience, requiring a perfect undertanding of the right dimensions of any item before the purchase.

On the other hand, more and more applications, such as motorized tv lifts, require knowledge of the right dimensions of the TV to obtain the best technical and aesthetic results.


The screens carried huge changes to our everyday life. However, there is an element, linked to the origins of TV, that has survived the screens evolution: the use of the inches to represent the screen size.

Over time everyone, from the industry professional to the housewife, to the teenager who buys his first mobile phone, have acquired the ability to link a size in inches to an actual screen dimension.
