When buying a TV, they pay attention to various parameters - the manufacturer’s brand, design features, the presence of certain functions, etc. However, perhaps the most important characteristic of this household appliance is, of course, the length of the diagonal of the selected model. The TV screen size of a modern build may vary. Choosing a model that is most suitable in a particular case, dimensions should be subject to several important factors.
What to look for when choosing a size
At the stands of modern hypermarkets of household appliances, a lot of TVs of different brands, designs and dimensions are usually exhibited. Determining the most suitable device size in the hall of such a store is visually rather difficult. The area of ​​the room itself, other working models, the height of the ceilings, etc. can distort the perception. Therefore, approximately the sizes of TVs by the owners of apartments and houses are usually determined even before going to the store.
The main parameters that should be considered when choosing the length of the diagonal are:
the size of the room in which the TV will be located;
the estimated distance between the screen and the future location of the audience;
design features of the model.
Room dimensions
Televisions in our time are installed not only in living rooms, but also in other rooms of the apartment. When choosing the most suitable model, the area of ​​the room should be taken into account. The dimensions of the TVs in cm (diagonal) are not officially determined at the moment. After all, most models are assembled using technologies developed abroad. The diagonal length of these household appliances in stores is usually indicated in inches.
Thus, the model 19-22 ″ is best suited for the kitchen. At the same time, installing a TV costs a little higher than in living rooms. In the bedroom of the standard five-story building, the TV at 22-26 ″ will look good. For the hall, of course, it is worth choosing a larger model - 32-65 inches.
Of course, the above figures are nothing more than a recommendation. The sizes of TVs that are ideally suited in a particular case may differ from the above. Even in a typical Khrushchevka, the choice of model dimensions is often seriously influenced by factors such as interior features, furniture size, how it is arranged, etc. In private houses, the area of ​​rooms may even be larger or smaller than the size of rooms in city apartments.
TV distance
This factor is usually decisive in selecting the most suitable model. The larger the TV’s diagonal is , the farther the sofa or chair should be located from it. The comfortable distance to the screen sometimes depends on the design features of the model. Today, on the shelves of shops you can find only two main types of TVs - LCD and plasma. In the first case, color transfer occurs through the smallest crystals. Therefore, the monitors of such TVs have a fairly high resolution and give a clear picture. And therefore, you can sit close to them, absolutely without risk of spoiling your eyesight.
Old-style plasma TVs should be watched from a slightly greater distance than LCDs. This is due to the design features of such models. The fact is that the color in such screens is transmitted due to the glow of the plasma in the cells (inert gas). The latter are relatively large. And therefore, when viewing such a TV too close, the image may seem fuzzy and vague. Sometimes on screens of this type even pixels are quite noticeable. Fortunately, the plasma models of the new generation of this drawback are practically devoid of. You can sit at the same distance from them as from LCD TVs.
Distance and screen sizes
What exactly should be the length of the diagonal at a given distance from the device to the sofa? The optimal ratio of these two parameters have certain values. So, the dimensions of the 32-inch TV allow, for example, to comfortably view it at a distance of 4 meters. What ratios of the length of the diagonal and the distance to the screen still exist can be seen in the table below.
Diagonal (inches) | Distance (m) |
17 | 2 |
25 | 3 |
32 | 4 |
37 | 5 |
55 | 7 |
80 | 10 |
Thus, in order to find out how long a diagonal should have for comfortable viewing, before buying, you just need to measure the distance from the sofa or chair to the intended location of the TV.
Distance to TV with HD picture
Recently, many models have appeared on sale that support including HD-technology. The latter provide a very high quality picture. Therefore, you can watch TVs with this screen resolution closer than usual. The table below shows the diagonal-to-distance ratio for HD-Ready technology and even more advanced Full-HD.
TV sizes in inches | Distance (m) |
Ready | Full |
20-27 | 1.5-2.1 | 1.1-1.5 |
37-40 | 2.8-3 | 2-2.2 |
42-47 | 3.2-3.6 | 2.3-2.5 |
52 | 4 | 2.8 |
How to convert inches to centimeters
The dimensions of the TVs, as already mentioned, are chosen, including on the basis that these devices should harmoniously fit into the interior. Therefore, surely many apartment owners are also interested in what real dimensions a model with one or another diagonal can have and how harmoniously it will look in a room.
They learn the sizes of TVs in cm (or rather, the length of the diagonal) by performing a simple mathematical operation. The calculation should be made on the basis that 1 inch is 2.54 cm. That is, 17 inches, for example, is 43.18 cm, 32 is 81.28, etc.
Additional factors
TV sizes can be selected taking into account several other parameters. When buying, be sure to pay attention to:
The thickness of the framing frame of the screen. In older models, it can be quite wide. And therefore, with the same diagonal size, the screen itself on such a TV may be slightly smaller.
Model weight. This option is relevant if you intend to purchase a wall-mounted TV and use brackets to mount it. In this case, the choice of model size can be affected by such factors as the holding capacity of the material of which the walls are made.
The most popular diagonal length
In modern apartments and houses, you can see TVs of almost any size. At the same time, both LCD and plasma models are popular. If we talk about the first variety, then in this case, the most widespread TVs with screen sizes from 32 inches and above. The fact is that models with a smaller screen are not able to support HD-technology. The dimensions of the TV 32 inches (or slightly larger) make it suitable for installation in almost any typical living room high-rise buildings. Plasma models are capable of supporting HD only with a diagonal length of at least 50 inches.
Size Dependence
Well, and, of course, you should choose a TV based on its price. The cost of this household appliance depends on its size directly. The larger the model, the more expensive it costs. For example, a budget Shivaki TV with a diagonal of 32 inches is usually sold for 15 thousand rubles. A 40 ″ model of the same manufacturer costs about 40 thousand rubles. "Shivaki" 55 ″ will cost about 50 thousand rubles. As you can see, the difference is significant. Therefore, before going to the store, you should, among other things, evaluate your financial capabilities.
The parameters discussed above are the main ones when choosing the dimensions of modern TVs. In most cases, 32 ″ is the most suitable diagonal length. A TV with a screen size of 81.28 cm in the standard Khrushchev’s hall will look quite harmonious, solid and modern. For the living room of the apartment in Stalin, a new building or a private house, most likely, it will be possible to choose a larger model.
