When thinking about buying a TV, one of the first questions that arises is how big it will be. However, this variable is dependent on others, such as the space we have for the new TV.

Buying the biggest TV doesn't always make sense! Know the proper diagonal for the space you have.

Let's consider that you have a room and want to buy a TV. In this room there is a sofa, which will be where you will sit (as a rule) to watch TV. What is the proper number of inches the TV should have? Deco Proteste did a set of tests and achieved the following results:

  • 32 ″ (81 cm): 1.5 to 2.3 meters;
  • 40 and 43 ″ (102 to 109 cm): 2 to 2.8 meters;
  • 46 to 49 ″ (117 to 124 cm): 2.4 and 3.2 meters;
  • 50 or 51 ″ (127 to 130 cm): 2.5 to 3.3 meters;
  • 55 ″ (140 cm): 2.8 to 3.6 meters;
  • 65 ″ (165cm): 3.4 to 4.2 meters.

Given the above values, we notice that there are different sizes that fit identical distances. Despite the large variations between the minimum and maximum distances, it has been found that if we keep a range of about 40 cm above and below the optimal distances, the vast majority of users say they maintain comfort. Overall, the optimal distance extracted from the test is about 2.3 times the diagonal value of the screen.

In addition to these calculations you can also use the simulator of RTINGS.

To determine the most advisable viewing distance, Deco Proteste took into account

  • the diagonal value of the screen;
  • the video signal (quality and resolution);
  • the picture quality of the television set;
  • the luminosity in the place;
  • viewing time (for longer periods, tolerance to larger screens and shorter distances decreases);
  • the content you are watching (eg news differs from a football game or action movie);
  • the personal tastes. Not all people feel comfortable at exactly the same distance.
