How to choose the right TV size for your home


Increasing competition always leads to lower prices, which only benefits users. Modern large-screen TVs have ceased to be a technique for the rich. However, this does not mean that it is worth chasing the maximum size, since although it can be bought cheaply, it is not a fact that this will give the expected effect. Comfort and pleasure do not depend on how large the screen will be, but on how correctly it is selected, namely, whether the diagonal corresponds to the distance to the eyes.

Choice of screen size per room

When choosing a TV, first of all, it is worth deciding where it will stand in the room, and where the user will be while watching. After that, the distance between these points is measured and divided by 2.5-3. The main rule for choosing a TV is: there should be 2.5-3 diagonals from the panel to the eyes. The latter is measured in inches, and an inch, in turn, is equal to 2.54 cm.

Thus, with a distance of 4 meters, that is, 400 cm, it turns out 400 cm / 3 = 133 cm. Now 133 / 2.54 = 52 inches. So, for a room of 4 meters, the optimal diagonal of the TV is 50 inches.

Finding the right TV for a room usually takes longer, but if you know the exact size chart and take into account the area of ​​\u200b\u200bthe room, you can get the right one much faster. A properly selected LCD TV will not cause visual impairment and will delight its owners for many years.

The calculated data are averaged and may be slightly adjusted. At the same time, do not forget about the design of the room, as well as think in advance about exactly where your TV will stand. LCD panel can fix it on the wall. The table for comparing the diagonal of the TV and the distance to it from the viewer is as follows:

  • 24 inches — 2 meters;
  • 32 inches — 2.5 meters
  • 40-42 inches — 3 meters;
  • 50-55 inches — 4 meters;
  • 65-75 inches — 5 meters.

How are diagonal and screen resolution related?

Choosing the best display and TV screen size is often not so easy, and the buyer must also take into account the resolution features of the selected device, as well as be aware of what acceptable formats may be. The thing is that the quality of the image and convenience in the process of viewing the broadcast on the screen depend on the resolution.

TV Distance Calculation

A few years ago, only FHD and HD TVs were presented on the market, so when choosing, it was recommended to divide the distance by 2.5. With the advent of higher resolution, this value has increased to 3, since UHD provides such a sharp picture that even sitting next to it, it is difficult to see individual pixels. That is why manufacturers «allowed» to sit closer to 4K TV, but this does not mean that you can ignore the rule of 3 diagonals and choose a huge screen.

The main problem is not that the pixels will be visible, but that, due to the too large size, it is difficult to completely cover the screen at close range. This leads to eye fatigue and can cause visual impairment.

Quite often, users wonder if it makes sense to buy a 4K TV to watch FHD content. Won’t the final picture be worse than conventional FHD TVs? You should not be afraid of this, since any modern TV with UltraHD resolution has Upscaling function, that is, programmatically “stretches” the FHD image to UHD. As practice shows, there really is a difference, and the result is better than when viewing the same content on FHDTV. How well the “improvement” mode works depends on the specific manufacturer and models.

Choosing a TV diagonal for the kitchen

It is obvious that it makes little sense to adhere to the recommendations of the data above when choosing a TV for the kitchen. A rare person is focused on watching while cooking or while eating, which means that you should not worry about how comfortable it will be to watch. However, for the kitchen there are other requirements. One of them is where to place the device. If the screen is 32 inches, which is too much for the kitchen, then finding free space will not be easy, but you can hang it on a bracket above the refrigerator.

And in general, hanging a TV in the kitchen is the most logical solution, but it is worth giving a choice swivel bracket, which will allow you to change the viewing angle depending on the position of the user. Also in the kitchen, a positive quality for a TV is the large viewing angles.

Important! When buying, you should clarify the weight of the TV, since strong walls are not always available. However, modern models for the most part weigh up to 5 kg, which means that if the wall is not made of drywall, then it will withstand.


The diagonals of modern LCD TVs can drastically differ in their parameters, but when buying, it must be borne in mind that the greater the distance from the viewer to the TV, the larger the diagonal of the device’s display should be. The user himself decides which options to choose, but in any case, you must always take into account the area of ​​\u200b\u200bthe room in which the TV will be placed.
