This is not ending here. Once you have learned to know the inches of a TV, it is time to calculate the distance that must be between him and the people who are going to see him. Obviously, it will not be the same if your screen is 50 ″ or 32 ″, just as its resolution also influences it.

Therefore, the larger the screen, the greater the distance for correct viewing. There are several online calculators to measure the distance to the TV, but to give you an idea, we give an example:

  • A 50 ″ TV with 4K resolution can be seen with a distance of less than 1 meter.
  • The same with FHD resolution we will have to see it at least 2 meters.

That is why we recommend calculating the size well and knowing the inches of a TV as well as the resolution and the distance so that you can get the most out of all the content. Samsung recommends measure the distance from which you watch TV and divide it by 2. The result will be the screen size “optimal” for a better viewing.
