TV diagonal in inches and centimeters

When buying a TV, the first thing they look at is the screen size. Many, out of inexperience, believe that this value is the total size of the technique, including the frame of the frame. But the diagonal is the size of the display itself, the matrix.

If you look at the international market, there this value is indicated in inches. The Russian people, in turn, are accustomed to a completely different measuring system, therefore, when choosing equipment, they have to find out the dimensions in advance. To facilitate this process, there are tables for converting inches to centimeters, which indicate the length and width of the screen.

Difference between an inch and a centimeter

Display diagonals are measured in inches for the reason that most of the television panels produced are produced in foreign countries.

An inch is a unit by which length or distance is measured. It has found wide application in the USA, although it was invented in England. As a general rule, 1 inch equals 2.54 centimeters.

A centimeter is a unit of measurement that is relevant for the metric system. 1 cm \u003d 0.01 m. Converting the diagonal of the TV from inches to centimeters is a simple task. Multiply inches by 2.54 to get cm (may be rounded as 2.5). And vice versa, knowing centimeters, they get inches – the figure is divided by 2.54.

Diagonals of displays are measured in inches for the reason that most of the television panels produced are manufactured in foreign countries in which this system of measurements has been adopted. In the USSR, the metric system operated, with centimeters.

For example, the TV model “Berezka 61ТЦ-311D” had a diagonal of 61 cm, which is indicated in the name. Today, TV manufacturers in Russia adhere to the European system when describing device parameters.

If you specify other values ​​in the model name, such as height or width, this complicates its presentation. It is for this reason that manufacturers “switched” to inches.

How the diagonal is measured

Sony KDL-32WD603

When buying a new TV, many users incorrectly determine its dimensions, believing that this value is the width between the corners of the case.

The main parameter is the diagonal – a line from one opposite corner of the screen to another, for example, from the bottom left to the top right. That is, you need to measure only the display, without taking into account the frame of the case.

In the name of TVs, the designations of the screen diagonal are now attributed. For example, the Sony KDL-32WD603 model. The number “32” is the dimensions of the display in inches. Conversion to centimeters:

1. 1″ = 2.54 cm.
2. 32 inches x 2.54 = 81.28 cm.
3. The manufacturer does not specify the display width and height. Here you can refer to the table.

And what if the diagonal is unknown for some reason. To do this, use a ruler and tape measure to measure the screen size horizontally and vertically. These numbers are squared, added up and taken as a root.

For example, having measured the dimensions, it turns out that horizontally 75 cm, vertically – 35 cm. The squares of the numbers are 5625 and 1225.

In total, it turns out – 6850. After extracting the root, 82.7 remains. But, since the measurements were carried out in centimeters, they are converted to inches: 82.7 divided by 2.54 \u003d a little more than 32 inches. A calculator is useful for such calculations, but now there are various services on the network that will do all the calculations in a second.

Which diagonal to choose

When choosing a TV, you should rely only on the screen size

The display diagonal is considered an independent characteristic, independent of other equipment parameters. The electronics market confirms this. For example, you can easily find a model with a small diagonal and high resolution, and vice versa, with a large screen, but a small resolution.

But this does not mean that when choosing a TV receiver, you should rely only on the size of the screen. To get a high-quality, detailed picture, consider:

• distance from the viewer to the TV;
• display resolution.

The resolution itself, in turn, depends on the characteristics of the matrix and the content being played (on a 4K device, you can run a video with a resolution of, for example, 1024 x 768 pixels, but it will “stretch”, due to which all imperfections will be visible) .

If the picture is high resolution, it is “assembled” from more pixels. And to evaluate the quality, you can reduce the distance to the panel.

If you watch low-quality content nearby (terrestrial TV channels), then all the flaws in the picture and video processing will be noticeable. If you increase the distance, the errors become less noticeable.

For example, there is a 32 inch TV used to watch broadcasts on the air. The recommended screen distance would be 3 diagonals, i.e. 32 x 3 = 96” or, if translated into centimeters, 96 x 2.54 = 243. Rounded up, it turns out to be about 2.5 meters.

With a display resolution of 720p, the normal distance is considered to be from 1.9 m. For Full HD content, even less – 1.3 m. These are the minimum allowable distances from which image distortion will not be visible.

It turns out that with an available distance to the panel of 2.2 m, you can take a TV with a diagonal of 37 inches (resolution – HD Ready). For Full HD models, the diagonal can be 52”. And for modern 4K devices – 60 ”at the same distance, without reducing the picture quality.

Knowing the viewing distance, you can easily choose the right size TV. Or the diagonal is selected first, and then the installation location. By correctly choosing and calculating the screen size, the user receives a high-quality picture, which increases viewing comfort. But, the larger the screen, the more expensive the TV model.

What are the dimensions of the TV? – 1a.lv

Until the 1990s, there was most often only one device with a screen in the house – a TV. In addition, the owners were more interested in the image on the screen than the object itself and its dimensions. There was no particular choice between different TV models. Their size was limited to “large” and “small”.

Today’s TVs are packed with cutting-edge features, high-tech, and come in a variety of sizes and designs. Therefore, at present, buyers are aware of the difference between one TV model and another. Often even the design of the room in which the TV will hang affects the choice.

With the advent of new and modern models on the market, it has become important to indicate the screen size, usually in inches. Take a look at the template prepared by the 1a.lv team, which will tell you how to estimate the dimensions of TVs in cm. One inch is equal to 2.54 cm. Thus, a 65-inch TV will have a width of about 55 inches or about 140 cm. To make it easier to navigate in sizes and convert them to centimeters, we have prepared a simple table that deciphers the dimensions of the TV in centimeters.

These parameters should also be taken into account when evaluating the most suitable computer monitors. This system is also used to specify the screen size of phones, tablets, and other devices.

Resolution

Modern TVs are available in three resolutions: 1080p, 4K and 8K. We recommend that you choose 4K TVs because the available content to watch in 8K resolution is limited at the moment. In addition, 4K viewing already requires excellent Internet speed, but it may not be enough to download 8K content.

This factor is taken into account when buying a TV, since TVs of the same size but with different resolutions will need to be placed at different distances. Also, if the space is small, it is better to choose a smaller TV with a higher resolution, because then you can sit closer to it, and the size is enough to cover the entire field of view. Pexels Different types of TVs should be viewed from different distances depending on their size and technology. This affects both eye comfort and image quality.

• Eye comfort – Sitting too close to the TV won’t hurt your eyesight, but your eyes may get tired. If you want to watch long movies, keep the right distance.
• Image quality – If you are sitting at the wrong distance from the TV, the picture on your new TV may not seem as clear. However, this will not be an objective assessment, as you violate the distance, which prevents you from enjoying the quality.

Pexels It is recommended not to exceed this distance by more than 3 times, as this may make it difficult to read the text or consider small details.

• 32″ (81 cm) screen best viewed from 1.2m to 2.40m.
• 50″ (127 cm) TV best viewed at least 1.9 m away.

Take a look at the TV screen size chart and recommended distances. It can also be easily calculated using the formula: TV dimensions in cm x 1.5 = recommended viewing distance.

Size	Middle	Far
19″ (48 cm)	0.7 m	1.4 m
26″ (66 cm)	1. 0 m	2.0 m
