How wide is a 55 inch TV? That's the answer

In today's TV sets, the size is usually between 45 and 55 inches. Here we talk about the screen diagonal, that is, the distance between the lower left and upper right corners. But what is that actually in centimeters?

How many centimeters is 55 inches?

55 inches equals 129.7 centimeters. With an aspect ratio of 16 to 9, that means 121.8 x 57 centimeters. However, you should consider beforehand whether such a large TV is necessary at all. Most apartments don't have enough space between the sofa and the TV to be able to see the whole TV. So you would have to move your eyes back and forth while watching movies, which can be very tiring in the long run.

1. In the past, there was a rule of thumb that you should not fall short of three times the screen diagonal as the distance to the TV.
2. With many modern televisions, this no longer applies, because even from a short distance is no longer recognized by the eye that it is individual points and not an overall picture.
3. Bei 55 inches, the distance would be just under 34 meters, if you calculate this with the rule of thumb.
