Recommended distance to watch the TV depending on its size
And when we talk about the size of televisions we always do so in terms of inches, a reference that also does not tell us anything about its general size. Therefore, how can you convert those inches to centimeters? Thus, when talking about a 40-inch television, for example, it means that The diagonal of its screen measures 40 inches; To go from inches to centimeters we will do it through a simple mathematical operation.
How to convert inches to centimeters
And vice versa. Thus, one inch is equivalent to 2.54 centimeters, so if you want to convert X inches to centimeters you will have to multiply the total number of inches by 2.54, in order to obtain the equivalent in centimeters. Thus, if you want to know how long the diagonal of a 40-inch television measures, you will only have to multiply 40×2,54, with a total of 101.6 centimeters screen diagonal.
Now, for the inverse calculation we must divide the centimeters of the television by its inches; For example, if the screen (not counting the frames) measures 110 centimeters, it will be enough to divide this number by 2.54. The result would be 110/2,54=43,307. Although the result is not exact, we must apply the equivalence with the closest number of inches, in this case, 42 or 43 inches.
How to calculate the measurements of a television
Once we are clear about how to calculate the diagonal of a television screen, the following question comes to mind: how can we calculate the width and height of a television from inches from the screen? In this case another variant enters the equation, which is the aspect ratio, or what is the same, the proportion of the screen with respect to the height and width, which is currently 16:9. This means that the screen has a ratio of 16 units long by 9 units wide; From here it is possible to calculate the measurements of a television, both its height and width, through a few simple steps.
Thus, with an aspect ratio of 16:9, we can calculate both the height and width of a television from its inches. Thus, to know the width and height of a television you would have to multiply the number of inches by 2.21 to calculate the width and number of inches times 1.245 To calculate the height, we insist, as long as the screen is of proportion 16:9.
With this method, a 40 inch screen diagonally it would have a width 88.4 centimeters and one height of 49.8 centimeters; Thanks to these calculations, you will be able to easily know the size of a television based on its inches and know if you have space or not before even buying it and having it arrive at your home. To facilitate operations you can count on a online calculator, the mobile calculator, Windows calculator or one you have at home.
Even so, below we provide you with a table with the most common measurements of televisions according to their inches:
- 22 inches: 48.4×27.40 cm
- 24 inches: 53.15×29.89 cm
- 28 inches: 61.99×34.87 cm
- 32 inches: 70.84×39.85 cm
- 37 inches: 81.91×46.07 cm
- 40 inches: 88.55×49.81 cm
- 42 inches: 92.98×52.30 cm
- 45 inches: 99.62×56.04 cm
- 47 inches: 104.5×58.53 cm
- 50 inches: 110.69×62.26cm
- 55 inches: 121.76×68.49 cm
- 60 inches: 132.83×74.72 cm
- 65 inches: 143.90×80.94 cm
- 70 inches: 154.97×87.17cm
- 75 inches: 166.04×93.39 cm
- 80 inches: 177.10×99.62 cm
Distance to the TV depending on its size
Once we are clear about the issue of inches and measurements in centimeters, we must also keep in mind the viewing distance recommended depending on the size of the television; And it is not the same to see a 65-inch screen from a few meters away than from a few more. The resolution of the television also comes into play here, whether 720p or HD Ready, 1080p or Full HD, 4K or UHD…
The larger the screen size, the greater the recommended viewing distance; The same thing happens with the screen resolution, since the higher the resolution the more the optimal distance. In this sense there are several online calculators that they recommend different distances depending on the size of the screen and its resolution; To give an example, on a 50-inch television, if it is 4K we can be at a distance of less than one meter, while if it is Full HD we will have to maintain a distance of about two meters.
That will be when you will have to do your calculations according to the Screen size, his resolution and the distance that you can afford in the place where you place the television.
