Table TV diagonal in cm and inches: how to measure the diagonal

Diagonal TV display is measured in inches. It is therefore important before buying a particular model of TV screen sizes present in our usual centimeters. Also need to know how far from the screen with a particular size of accepted conduct view. This will determine the level of comfort in the contemplation of films, series and programs. Additionally, this article useful information about the Screen Aspect Ratio will be revealed, told how to translate inches to centimeters, and presented the finished table with all calculations.

TV sizes depending on the diagonal

Without a doubt, the size of the TV is directly dependent on the diagonal. The more screen size, so he, respectively, and more. And the more the display - the more the TV. Here everything is very, very simple. However, before the TV screen size is not matched. Because the display was significantly smaller than himself. Thus, speakers and various interfaces (as in older models, when there was no remote, and even controls), located on the front surface, exactly where the screen was. That is why to calculate the dimensions of the TV based on the diagonal became impossible.

Currently, the progress has reached such proportions that the screen - it is practical and has a TV. The only exception is the thickness of the body (usually no more than several centimeters) and the frame of 1-2 cm perimeter of the display. Thus, based on the size of the matrix, it is very easy to imagine the dimensions of the device.

Reference! During the Soviet era, when the country was engaged in manufacture of such equipment, diagonal reflected in centimeters. Now the design, development and production is concentrated abroad, where a system of measures different from our part of the world. That is why the measurement of the size of the screen is held in inches.

How to convert inches to centimeters

Translation inches to centimeters is very simple and nezateyliv. Inch - a unit of measure. To find the TV screen size is enough to know its diagonal inches. Then it will be possible to easily convert inches to centimeters, knowing how many centimeters equals one inch.

It is known that inch is 2.54 cm. This means that the standard in size for current times 32 inch TV, has a size of 81.28 cm. The same way it is easy to know the size of any screen. We need only inches multiplied by a value of 2.54.

It should also be noted that it is necessary to choose the right distance to the TV. The larger the matrix - the farther the viewer should be on TV. And, accordingly, the smaller it is, the closer you need to be positioned to the TV. Otherwise, enjoy comfortable viewing will not work. If the screen is too large when viewed from a distance, you can see all what is shown on the screen, it will be impossible, and if small, then the picture would have peer. This greatly interferes with vision - in this case it is subjected to excessive stress.

It is considered that the distance to the TV should be 3 or 4 diagonal of its screen. In other words, if the screen size is 32 inches (81 cm), then the distance should be 2.4 - 3.2 meters. The larger the display, the diagonals may be greater. That is, to comfortably keep viewing on small screens should be considered as an acceptable size in number of three diagonals or a little more. While on a huge display of over 50 inches, this figure could exceed more than four screen sizes.

Aspect ratio, diagonal and resolution

Much more important relationship the Screen Aspect Ratio and its diagonal and resolution. It should be to run ahead and say that now TVs are available with display, the aspect ratio of which is 16: 9, the diagonal can be absolutely anyone. Resolution may also be different in 1366 × 768 pixels (HD Ready), 1920 × 1080 pixels (Full HD) and 3840 × 2160 (Ultra HD). In other words, when different diagonal resolution may also be different, but will remain a single aspect ratio.

However, recently it was still possible to meet the PC monitor where the aspect ratio of the matrix was 4: 3 and diagonal could be either 17 or 19 inches. A resolution was either 1024x768 or 1280x1024 pixels.

Important! The transition to the aspect ratio of 16: 9 has been made for a reason. The fact that the monitors with an aspect ratio of 4: 3 are almost square. A human eye is known to read more information in width rather than in height. Matrix widescreen 16: 9 made it possible to perceive more information, and to do so has become much comfortable: in view of the practical does not see anything except the TV Images.

Thus, the relationship between the aspect ratio of the matrix, resolution of the captured image and diagonal once expressed more distinctly. But at the current time only constant aspect ratio (ie 16: 9), while the screen size and resolution can be anything. For communication between the producers screen resolution and space do not exist: they can make any matrix. But the average user, it is desirable to read the warning below.

When you select the TV must be remembered that the higher the resolution - that will be more clear look at the screen image. However, it is observed on the condition that the playback video will match the resolution of the TV screen. Another caveat: with the same resolution of the two televisions, for example, Full HD, more clearly and precisely will appear on the picture of them, whose screen size will be smaller. Thus - a huge display should provide maximum resolution in Ultra HD transmission for maximum picture clarity.

How to measure the diagonal TV

When selecting the TV screen measurement of the majority of users it is carried out incorrectly. They believe that its size - it is the distance in width from one end to the other. Far from it. After a diagonal of the rectangle is called a line drawn from the lower edge of one side to the upper edge of the other side. Example: The distance from the lower left corner of the display to the upper right. The measurements being made only of the matrix itself, without taking into account the framework of the TV. Yet there is a nuance: TV manufacturers, especially with regard to the Chinese companies, some of the models leave the black edge of the matrix, which does not reproduce the image. At the same time they do not close this dark plot frame. Thus, before turning on the TV screen may appear much larger than it actually is.

Another nuance lies in determining the size of the display in curved TVs. With its measurement have difficulty only with roulette. Help out here as conventional tape centimeter, which is twisted by hand, like Hank some tape. He is flexible, so do not hurt the screen.

Much more difficult to determine the distance to maintain a comfortable viewing on today's curved TV. The point here is this: if you take a normal TV and the one with the bent matrix, then it turns out that the curved TV model will be slightly longer, in spite of the same display size. Here the usual calculation of the distance in the diagonal 3-4 is not relevant. And you will need to determine the distance for comfortable viewing, based on the width of the screen. You just need to measure the width of the curved model in a shop and then compare the received measurement with the width of a conventional TV. Make it easy, because the data on the display diameter for conventional models are already known.

Screen in inches	Screen width in inches
32	70
40	88
42	95
50	110
55	121
60	132
65	143
75	166

Knowing the width of the display, depending on its dimensions, you can easily compare these data with the width of the curved TV. Information about the width of the diagonal and the desired distance, which should be placed conventional TVs (to be presented later), is known. Therefore, to determine this is the distance in models with curved screen will have no difficulty.

Table diagonal TV in cm and inches

A special table was compiled in order to not have to translate mentally inches to centimeters, which you can use to instantly get information. Along the way, in this table includes information on the distance at which the TV should be positioned relative to the viewer. In the process of selecting the TV to make any calculations are not very convenient. And it is not necessary, all information is available in a simple and understandable table:

inches	centimeters	Viewing distance (in meters)
22	56	1,70 — 2,40
32	81	2,40 — 3,40
37	94	2,80 — 3,90
40	102	3,00 — 4,20
42	107	3,20 — 4,50
46	117	3,50 — 4,90
50	127	3,80 — 5,30
55	140	4,20 — 5,80
60	152	4,60 — 6,30
65	165	4,90 — 6,80
75	190	5,70 — 7,90

Many highlighted the variation in distance from a few tens of centimeters to a few meters depending on the dimension of the display. Of course, a comfortable distance is individual for each person. But it is necessary to take into account that the greater the display, the more of it you need to be located.
