What is the diagonal of the TV for a distance of 3

Optimal TV Distance

Extremely important: remember the square and shape of the room. Given this, you can calculate the diagonal of the TV. For an illustrative example: model 40 ″ from the viewer is best installed at a distance of up to 3 m, 50 ″. 4 m. But these figures are guided by TV with 720×576 pixels.

Below is a table in front of you, according to which you should start when choosing a place for installing the device and selecting a model.

Distance Screen diagonal in inches
1.5-2 m 14-17
2-3 m 21-25
3-4 m 26–32
4-5 m 34–37
5-7 m 42–55
7-10 m 61-80

recently, to calculate the diagonal, a common indicator for all existing types of TVs was used. 3 or 4. During the purchase process, it was necessary to calculate the optimal distance from the installation site of the TV to a sofa, bed or chair, and then divide by this coefficient. But the formula is considered to be more suitable for the very first TV models with SD-resolution.

After Full HD and Ultra HD began to go on sale, the formula calculations were changed. This process was influenced by the following factors:

  • a high resolution ratio contributed to an increase in image quality, and now the viewer could watch their favorite programs and films at a short distance;
  • modern technology has no negative impact on human eyes.

Such changes became the basis for calculating new coefficients. We got the following indicators:

  • HD Ready. 2.3;
  • Full HD. 1.56;
  • Ultra HD. 0.7.

For clarity, let’s take an example. The user intends to install the Full HD model somewhere 2.5 meters from the sofa. We divide this distance in cm by the coefficient corresponding to this resolution, and we get: 250 / 1.56 = 160 cm. What we got will need to be converted into inches. Accordingly, a TV of 60 or 55 inches is suitable for the selected distance. If we are talking about buying a model with HD Ready 250 / 2.3 = 109 cm. 42 inches model is suitable.

The ratio of the screen height to its width is a parameter that depends on the model and manufacturer. On the label, modern TV manufacturers use a systematic gradation, dividing into two types. 4: 3 and 16: 9. These concepts indicate the aspect ratio of the TV screen.

What resolution to choose a TV

The new 4K technology, also known as Ultra HD, has been used by manufacturers not so long ago, but is already gaining momentum in popularity. Especially for those who like to watch high-quality video, 2D and 3D graphics, and for gamers, this is the ideal solution.

4K significantly outperforms Full HD. the resolution is increased by 4 times. But the price is also higher. Full HD has a resolution of 1920×1080, for Ultra HD. 3840×2160.

To get the most out of your TV with Ultra HD, it’s best to buy a 40-inch TV or more. At the same time, it is impractical to install such a technique in a room with a small square, despite the fact that even with a small distance, the image will be gorgeous.

And here it is also important to consider your budget, since 4K is more expensive than Full HD. In addition, think about what exactly you intend to watch on TV: if only analog broadcasting, then there is no point in overpaying.

What diagonals and resolutions do TVs have

The diagonal of the display is prescribed by manufacturers immediately on the device labeling. these are the very first two digits. This specification is equal to the distance between 2 opposite corners of the monitor. This indicator is used by all brands that produce TV. over, the screen size is written in inches.

If you have not previously encountered how to choose a diagonal, take note of the following statements:

  • the diagonal directly affects the price of equipment.
  • the area of ​​the room affects which inch is considered optimal for it.

There is also the concept of “aspect ratio”. New TV models are presented as 16: 9, this format even supports analog broadcasting. If you have not figured out how to choose the right TV diagonal, initially decide for which room you are buying a model and what goals you are pursuing. What programs will you watch on TV, analogue? Then there is no point in overpaying. If the quality of the picture is important to you when watching your favorite movie, you have to pay a little extra.

The most popular are models with Full HD, HDR. A high pixel density is the maximum clarity and quality of the picture. When the picture includes a normal number of dots, you can enjoy content without compromising quality even from a short distance. Screen 32 ″ and 625 pixels. it is better to keep the distance to the viewer up to 2.5 meters. Screen 32 ″ and 720 pixels. distance of about 2 m.

How to choose a TV based on room size

To choose a TV, start from the characteristics of your room, in particular from the arrangement of furniture and the place where the TV is planned to be installed. Concerning the last point. It is necessary to perform a number of actions, namely to make visually marks for yourself where the TV will be placed in order to visually assess the correspondence of the TV to the room.

Remember that the concept of the optimal TV diagonal varies in accordance with the characteristics of the room. Sit on a sofa, bed, table or chair from which you will be viewing. This will allow you to assess the level of comfort.

In addition, remember about the features of the room. For example, for a kitchen, the ideal solution is to install the TV only on the wall. This rule applies to small living rooms and bedrooms in order to save space. over, this installation method reduces the risk of equipment damage.

Not sure how to calculate the diagonal of your TV? Use a YouTube video. There are quite a lot of videos in which, using specific examples, it is described how best to calculate the size of a room for TV correspondence.

Consider the distance from the TV location to the viewing point. Previously, a table was presented in front of you. Remember that a minimum of 2 meters is considered optimal. But take your time and do the calculations yourself to make sure which TV is right for you.

  • Better not to put it by the window. Because in this case, the image will be dim and the viewing comfort will be reduced to zero. Have to constantly play with brightness and contrast.
  • Away from both interior doors and the closet. As the risk of the door hitting the screen increases.
  • Clearly in front of the viewer. Therefore, you need to look as much as possible from all viewing points, whether it will be comfortable to enjoy a movie or broadcasts.
  • Consider TV backlighting as watching broadcasts in the dark is considered harmful, increasing eye strain.
  • Place so that the screen is not exposed to direct sunlight and the TV is located away from batteries.

How to choose a TV diagonal for a room: optimal viewing distance and types of resolutions

A TV in an apartment or in a house is not a classic TV like several decades ago. Now it is not just an opportunity to watch your favorite programs, films, news channels. modern TV models allow you to enjoy clear images and sound, and thanks to “smart” options, they can easily replace a laptop or computer. It remains only to choose the most suitable model for yourself.

The list of manufacturers and the range of available models for purchase, depending on the parameters, is the broadest. Therefore, the appearance of difficulties with choosing a TV is a regularity. In order to significantly reduce the list of applicants for a purchase, but also make the right choice, you need to understand one important question. what diagonal should a TV have? Here you need to remember that the size is influenced by the resolution of the model, for which room the TV is purchased, what is its area and what is your budget. So, for those who are looking for TV, consideration of the question of how to choose the diagonal of the TV will be relevant.

What diagonal of the TV to choose for the kitchen

To be honest, it is extremely rare that someone is purposefully watching TV in the kitchen. Accordingly, buying a TV for any kitchen is largely for background noise, or simply the ability to follow the news, dry songs, while not being distracted from cooking and cleaning. So the size of the TV for a given room doesn’t really matter. But at the same time, there are a number of factors that are best taken into account when buying kitchen appliances:

  • Place of installation. The large diagonal narrows the list of available placement locations. If you choose 32 inches, you can easily hang it with a bracket above the refrigerator or on an empty wall. But it is difficult to place 40 inches and above in the kitchen.
  • Weight of the device. The next point is in favor of more compact options for the kitchen. In the kitchen, you cannot put a TV on a curbstone or in a niche in the kitchen wall. If the diagonal is large, accordingly, the weight will be considerable. Therefore, in order to avoid a force majeure situation, it is enough to look at what the walls in the kitchen are made of.
  • The size of the room. If we are talking about a kitchen in its classic presentation, then 32 inches would be the best option. If the kitchen is a living room, then you need to take into account the dimensions of the room and the point where you can install the device. Depending on these factors, the diagonal may be larger.

Selection features

Remember that the calculation of the diagonal is considered especially important, but this figure will vary according to the type of matrix. Therefore, if you set out to correctly and correctly choose a TV, do not be lazy with Honor even the most insignificant, at first glance, moments. This will allow you to achieve a great result.

How to Measure the Right Distance Between Your TV and Couch

An LED TV is an LCD matrix. The backlight module consists of small LEDs. The technology, according to experts, is considered one of the most effective, because it provides rich and deep color. LED panels are a guarantee of excellent color reproduction, which contributes to the expansion of viewing angles. Comfortable viewing from anywhere in the room.

For OLED models, pixels are illuminated in a personalized order. Thanks to this technology, a high-quality contrast picture with excellent color rendition of 2-5 nanometers is achieved. This is especially visible, if you turn on the dynamic scene, there will be no blur.

Models that support LED, OLED technologies are among those that are harmless to human eyes. Therefore, when buying such equipment, the user may not worry about the distance from the TV to the place from which films, programs will be watched.

As you can see, there are different situations, so it is difficult to immediately tell which diagonal is better, it is important to take all factors into account. Next, let’s talk about them in more detail.

There are special online calculators that allow you to calculate the diagonal of your TV. It is enough to enter the distance between the device and the place from which you plan to view the content, plus the model resolution. Then you will get the optimal result for you.

What diagonal of the TV will be optimal for home viewing

It would seem that the matter is obvious: the larger the screen diagonal, the better. Meanwhile, when choosing a TV, you need to take into account the dimensions of the room in which we will put it, and, consequently, the distance from which we will watch the picture.

How to choose the best screen size

Impressive looks and immersion shouldn’t be the only criteria for choosing a screen size. A screen that is too large in relation to the size of the room can be overwhelming. So what’s the correct size?

There is an easy way to match the size of your TV to your room. To find the optimal Full HD screen size in inches, multiply the sofa-to-receiver distance in meters by 25.

For example, if the TV should be 2 meters from the sofa, its screen should be 50 inches. If the distance between the sofa and the TV is 3 meters, the recommended diagonal is 75 inches.

In the case of Samsung SUHD and UHD TVs, due to the higher resolution, picture quality and detail, the distance between the receiver and the sofa should be multiplied by 39.

So a TV set 2 meters away from the sofa should be up to 78 inches. If the sofa is 3 meters away from the TV, the UHD receiver must have a 117 ” screen.

The era of big screens

It is widely known that large-screen TVs are becoming more and more popular. In the near future, the average size of home TV screens will exceed the 40-inch threshold.

According to data compiled by IHS, the average screen size of TVs sold worldwide in 2015 was 39.4 inches. It is expected to be 40.8 inches next year.

In large global markets such as the United States or China, these changes are even more pronounced. In the United States, the average diagonal of TV screens purchased this year was 42.6 inches, and should increase to 44.5 inches in 2016.

Similar figures for China are 43 inches in 2015 and 43.9 inches next year. In the case of UHD TVs, the diagonal is even larger. In Korea and Australia, Samsung’s most popular UHD TV size this year is 55 inches.

Another trend contributes to the increase in the diagonal of the TV screen. the smaller and smaller frame size. In the past, the frames around the screens of large TVs were several centimeters wide, it was not so much the size of the screen that was impressive as the size of the entire device.

Today, the framework is so narrow that it completely merges with the environment. This allows the 55 ” TV to take up the same space as the previous generation 46 ” receiver.

UHD TV screen could be larger

UHD TVs have next-generation screens that have four times the pixel density of traditional Full HD TVs. Full HD screen has a resolution of 1920 by 1080 pixels.

In the UHD standard, the resolution rises to 3,840 by 2,160 pixels, resulting in amazingly clear images. Therefore, a UHD TV can have a larger screen than a Full HD TV at the same distance from the sofa, and despite this, individual pixels will not be visible and the image will not be tiring on the eyes.

From what distance should you watch TV? The International Organization for Standardization ITU-R suggests that in the case of a 50-inch Full HD TV, the optimal distance from the screen should be 2 to 3 meters.

If this distance is less than 2 meters, then you should choose a TV with a smaller screen or choose a UHD receiver. Otherwise, you may experience some discomfort. Images on a 50-inch UHD screen can be viewed comfortably from just 1 meter away. For an 85-inch UHD TV, the optimum distance is 1.6 to 3.3 meters.

It is worth while being guided by common sense. For the optimal screen size is not only a matter of taste, but a logical pattern.

Specification Based Recommendations

The calculation of the distance between the TV and the eyes is made correctly taking into account several more parameters: the quality of the matrix, the declared resolution of the TV, contrast and screen formatting.

Good image quality is now determined not by the dimensions of the device, but by the quality of the matrix and other technical characteristics.

Screen size

A common misconception when thinking about how to choose the size of a TV is that the diagonal size of the screen determines good visualization and there is a direct connection between them. However, even on the screens of smartphones and laptops, the image is clearer. Achieving the desired viewing angle can only be achieved by fixing a fixed distance to a relatively large screen (43 or 49 inches) or by reducing the distance to TV receivers. But in this case, even with guaranteed security, it is important to take into account the number of pixels.

At what distance to watch TV: table of optimal values

The distance to the TV, depending on the diagonal, is certainly an optimal parameter to be taken into account, which must be determined responsibly. Physicians have long been concerned about the problem of the influence of a television screen on vision. Nevertheless, the practice of calculating the distance from TV depending on its diagonal is still not widespread.

The overwhelming majority of people, starting from middle age, spend most of their free time watching TV and movies. This is understandable, given today’s realities. every home has a TV (despite the claim that computers are replacing it).

Plasma LCD and LED TVs

Until recently, they were recommended as the newest and most technologically advanced models in the world of television production. However, if you carefully read the instructions of manufacturers and doctors, then you can calculate the approximate distance here according to the same principle: both of them recommend choosing the required value when buying, multiplying the diagonal by 5. The optimal viewing distance is selected by the formula:

  • D is the length of the diagonal;
  • L. the required distance to the diagonal of the TV;
  • K is a special coefficient, the meaning of which is clear to specialists and has a value from 3 to 6, depending on how the TV diagonal should be located, whether the maximum or minimum permissible range is needed.

According to this formula, MDD (the minimum length at which the viewer should be before the screen), with D (diagonal parameters) 70-80 inches (and 65 too), should be 5 m. Choose the ratio of the diagonal to the location of the device and furniture, where the viewer will sit, much easier than making a choice of the diagonal of the TV, and then trying to attach it depending on the number of required meters.

CRT, or CRT TVs, are a type of standard device for watching TV programs, in which the required distance practically did not depend on the size of the screen. The required distance to the TV is also calculated from the size of the diagonal. It is quite simple to determine it by measuring the distance from the TV to the eyes (approximately at the place where the viewer will sit), and then divide by 5.

diagonal, distance

Naturally, a distance of 2 meters will give a figure of 40 centimeters, and if you divide this figure by 2.54 (the value of an inch in centimeters), you get about 16 inches. If the diagonal is 32 inches, then there should be 4 meters from the TV. The last CRT in these TV models, with a large screen, was released in 2014. This is due not so much to its shortcomings (of which there are relatively few), but to fire hazard and harmful radiation.

What is the best distance to watch 4K TV

4K is an abbreviation for 4K resolution in digital cinema and computer graphics. To obtain a high-quality image, the optimal aspect ratio of TV, monitor and projector in the 16: 9 aspect ratio.

The approximate date of the appearance of the technology is 2005, but it still has not received proper distribution due to the need to purchase additional equipment and a small amount of available content.

  • Fans of new technologies convince the average consumer that the standardized scan resolution of 3840×2160 pixels allows you to watch a higher scan (4096×2160), while providing impressive differences in clarity, sharpness, color reproduction and even contrast.
  • They also assure that as compensation for expensive cables and ports with increased bandwidth, 4K TV can be watched from almost any distance, and the selection of dimensions here should be done only taking into account the room. In fact, in this case, the calculation of the required size of the diagonal is carried out only taking into account the optimal distance.
  • The problem of choosing from what distance it is better to look at the image is precisely the multi-pixel. For a large screen or monitor, 2.7-3 meters is recommended. But, according to experts, in this case, the human eye does not see all the subtleties provided. If the distance from the screen to the viewer is less than the prescribed distance, 4K will clearly demonstrate the pixels, but will not give the desired picture clarity.
  • Therefore, it is believed that the table will help to determine the necessary distance, which is difficult for an uninitiated person to understand. Meanwhile, most buyers of new models are trying to calculate a safe distance, and at the same time, a high-quality image is not the most important for them.

Calculation of the ratio between the screen diagonal and the distance from the intended place of viewing the TV. this is what determines the health of the eyes and the quality of the picture on the screen. If we take into account only the resolution of the TV receiver, and do not care about the health of human eyes, then the novelty and manufacturability of the device will not be appreciated at its true worth.

Determine the diagonal taking into account the size of the room

To correctly determine at what distance to watch TV, you must first of all proceed from which type of TV is selected. With the existing variety of models, it is difficult for an incompetent person to understand matrices, resolutions and other wisdom.

The main thing here is to assimilate one immutable truth. the larger the diagonal you select, the further you will have to sit from the screen. And the main thing here is not the quality of the image transmitted from the antenna, but the ability of human vision to perceive the video image.

If someone tried to enlarge a picture from a mobile phone, a strong increase (zoom in) leads to disintegration into blurry spots, and no gadgets and cars will save the photo, and mobile tariffs are not to blame for this. It all depends on where the screen is. Sometimes the image is blurry up close, but if you look at it from a distance, everything will be clearly visible on it.

Therefore, before giving preference to a huge screen, you should measure the room where the new device will be lovingly installed.

The standard requirement for distance from a 55-inch screen is 4.5 m. If the size of the room allows it to withstand it, everything is fine. If you choose a TV with a 32-inch screen, you will need to watch it from a distance of 2.5 m.Correctly selected technical characteristics will make the image clearer and more beautiful than that of a TV-receiver with a large screen, but with worse matrix characteristics.

You can follow a different principle and calculate the diagonal according to the proposed formula. measure the distance from the viewing location to the intended location of the purchase. The length will turn out in cm, but you need to divide it by 5, and then by 2.54 (inch), and you get the optimal size of the diagonal, which you can set and look without prejudice to your own vision.

Screen resolution

Television does not always broadcast a high-quality image. In 4K, you need an app and additional accessories to get quality content, otherwise the software will correct the imperfections of the map, and if you sit too close, you may see a blurry image. The same rule applies when zooming in for a photo. How many pixels are needed to maintain a normal image?

For everyday use and extended viewing, manufacturers recommend choosing high-definition TVs. It is they, even with a relatively small diagonal, that allow the viewer not to depend on the distance. With such devices, you can afford to sit closer, expand the possible viewing angle and even activate the peripheral vision that is important for a person to the maximum extent.
