Nobody knows the value of a TV until it goes through a pandemic. Suddenly, everyone started to appreciate this appliance that is ubiquitous in every home in the world, but that was kind of relegated to the background at the expense of the amount of hours we spent in front of our cell phones.
Gathering the family to watch series or just “hypnotizing” the little ones to work in the home-office, we realized the importance of the size of the TV in relation to the space in which we live. When looking for the ideal TV, the first question that arises is: TVs are measured in inches. Because?
The maintenance of inch TV measurements is a mystery, but its origin is due to the fact that the United States was the country where these devices began to be produced. Interestingly, even after the rest of the world adopted the metric system (only the USA, Liberia and Myanmar adopt the so-called “imperial system”), the tradition continues today.

The TV measurements, as we said above, continue to be calculated in inches – a measure that is equivalent to 2.54 centimeters and are represented by the double quotation mark (“) symbol. What is measured is the size of the screen, drawing a diagonal line , which runs from the upper end of the left side to the other lower end of the right side, or vice versa.
To get an idea of what that means, just check how many inches your current TV has, multiply that number informed by the manufacturer by 2.54. A device that is nominally 40 inches, for example, has a screen that diagonally measures about 1.02 meters.
That done, another question comes up: is it true that the bigger the TV, the better? Not always! Experts in the subject explain that each environment has a TV size limit. In addition, the way people get comfortable and the use they make of TV also influences the perception of images.
Thus, having knowledge about the measurements of TVs is essential to, before buying, know what is the best size for the environment where it will be installed.
How many inches will your new TV have?

When buying your new TV, regardless of whether it has an LCD, Plasma or LED screen, an important detail to be considered is the distance between the sofa (or bed) and the device.
So, buying a 65 “TV, for example, and placing it in a small environment, will cause immense discomfort because, after a while, the brightness of the screen will start to bother your eyes and the viewing of moving images very much close up can cause a kind of vertigo and headache.
To achieve a view that is both comfortable and clear of the images displayed, you must be between a minimum and a maximum position of the TV. In addition, the eyes should be directed and aligned right in the middle of the screen. Below is an infographic with recommended average distances for TVs with Full HD resolution.

TV size and seat distance
If you want to establish a size that can be considered “ideal” of TV in relation to the distance from the seats, there is a rule of the Society of Engineers of Film and Television of the USA (SMPTE), that is to multiply the distance between seat and TV by 0.625 .
So, if you sit normally 2.7 meters from your TV, that means that the diagonal line of the screen will have to measure 2.7 x 0.625, which results in 1.69 meters which, converted to inches (just divide for 2.54 remember?), will result in 66 inches.
If you are still not convinced that this is the ideal size, you can do a “test” by cutting a cardboard the size of the suggested TV screen and placing it on your wall. This will then be the size of your turned off device. Remember that when the TV is there, and on, it will look incredibly bigger.
