Diagonal 7 inches

What are the sizes of tablets in inches: table

The size range, or screen diagonal, of a tablet is indicated in centimeters (cm) or inches (“), which is equal to 2.54 cm, and is indicated by double or single upper quotation marks. In most cases, all manufacturers use English measurements.

• 7 inches. The diagonal resolution is either 4:3 or 16:10 (less often 16:9). Ideal for mobile devices slightly larger than a smartphone to play mobile games, surf the web and communicate outside the home while you're on the go studying. It will especially appeal to children and petite girls due to the ability to hold the device firmly even with small hands. The keyboard on this screen is a little small, so handwriting enthusiasts may find it awkward.
• 8 inches. Also with a length to width ratio of 4:3 or 16:10 (sometimes 16:9). Already better for watching movies, but in models with a resolution of 4:3 you see an unpleasant black frame. A tablet with this diagonal is an excellent choice for those who like to keep notes on a calendar, take notes for work, or additionally use a universal device as an e-reader.
• 9 inches. So far it only exists in 16:10 resolution and is actually rarely released as it makes little difference to the user experience but carries more weight due to it being less portable and costing more.
• 9.7 inches. The standard diagonal of classic iPad models with an aspect ratio of 4:3. Such a brick is difficult to hold even with two hands, so using mobile applications and games on the go will make the owner sweat a lot. To solve this problem, you can purchase a special gamepad for mobile devices. The keyboard is easy to press and watching videos is quite comfortable. But the disadvantages are more weight, as well as battery consumption due to the increased number of pixels, since image development is much more difficult.
• 10.1 inches. It has a resolution of 16:10 or 16:9. This tablet is of little use for talking or listening to music, but is recommended for watching movies, since all video formats are played in full screen mode without an annoying black border. Web pages via a mobile browser will sometimes display crookedly because they are primarily designed for a 4:3 square.
• Over 12 inches. This is quite a rare occurrence because not only are they heavy, but they are almost as big as a small laptop. It is not mobile at all, and there is no demand for it.
• 17.78 cm. Comfortable and lightweight, as well as the cheapest option that is easy to hold with one hand. Not a bad option for reading books, but not the best for browsing the web due to difficult navigation. Not suitable for use with word processors or graphics. Height and width 15.1x9.4 cm.
• 20.3 cm. They have the same characteristics as the 7-inch. However, they have a competitive advantage that sets them apart from others. They are better for reading websites and e-books, watching videos, but at the same time, they are mobile enough to use on the go. The disadvantage is the high price. The form factor is 17.2x10.8 cm, respectively.
• 23-25.7 cm. Large models are only suitable for watching movies or online games and perhaps reading newspapers or magazines. They are mainly suitable for office work, spreadsheet editing, calculations, document writing, etc. Length and width vary from 19.4 x 12.1 cm to 25.9 x 16.2 cm.

length and height (width) of the TV in cm

A 10-inch diagonal is how many centimeters the screen of a tablet or TV is; its width and height dimensions are a common question that Internet users ask in the search bar. The diagonal itself is not a very convenient designation for a person who is going to buy a tablet or upgrade their TV. Because the distance from the bottom corner to the opposite top corner does not give an idea of ​​​​what the width and height of the monitor is, for example, 10″. And measuring in inches forces you to look for the answer - how many centimeters.

Tablet

Briefly about the proposed acquisition

The screen diagonal of a 10-inch tablet is 25.4 centimeters. Determining how many centimeters a given figure is in inches is quite simple, even if a person does not have special knowledge of the metric systems of different countries. To calculate, he just needs to use a conversion table or look up the value of an inch in a reference book.

Length converter from centimeters to inches and vice versa.

A tablet screen, computer monitor, iPhone or TV, any purchase in the field of electronics, including a laptop necessary for work or play, in an online store or electronics supermarket will be equipped with this characteristic.

The most popular format for office programs is 9.7 inches. A tablet screen with this diagonal is often used as an additional monitor when working on a personal computer. A 10 or 10.1″ diagonal is a tablet screen produced for those who want a larger screen length, rather than a square one, with a 3:4 aspect ratio.

In the country

They also produce a 10-inch tablet or TV screen with a diagonal of 25.4 cm. This product is not the most popular. It's awkward to carry and impractical for one-handed gaming when it's not on a stand or table. Experts recommend this screen size for permanent installation.

If you purchase a keyboard and mouse for your tablet, the length and width (height) will not be an obstacle to comfortable use. With an aspect ratio of 16:10, this is a normal device used as a TV.

A game

It is convenient for watching TV programs, series and movies, and for working with office programs. Its dimensions and weight will prevent you from taking it with you all the time. But a tablet diagonal of 10″ is the optimal size to see the image better.

How to relate metric measurements

Using tablet size in cm or inches diagonally is a popular practice in selling electronic equipment. It has different types, these products are produced in different countries. Some of them do not use the meter and centimeter as a metric unit.

In the office

Therefore, the screen size is usually indicated in inches. On the price tags, the technical characteristics indicate the diagonal, which is more understandable to specialists, rather than the length and width (height). For the domestic user, earlier, when only TVs produced in their own state were in use, it was typical to see the indication in cm.

To find out how many cm the diagonal of a 10-inch tablet or TV (monitor) is, the number of inches is multiplied by 2.54 cm. It is in this digital value that an inch is expressed - a unit of measurement of a somewhat outdated English system of measures.

In the shop

The meter and centimeter obtained by using a special conversion table or an online calculator to calculate how much 10″ is are also not very informative.

If a consumer of electronic products is interested in how long a device is, additional measurements will have to be made. Some points to note:

1. A tablet or laptop used as a TV or for working with office programs and subject to permanent installation, with a diagonal of 10″, is equipped with frames.
2. Many manufacturers provide different sizes and functionality of this frame. This could simply be a visual field limiter or a location for installing control buttons.
3. To find out what the height or width is in this electronic device, even at the specified 10″, it is not enough to simply convert each inch to a centimeter. Moreover, it is not difficult - just multiply 2.54 cm by ten inches.
4. The diagonal of a rectangular screen is not its height and width. Moreover, if the frame of the device is wide enough, and to place it in a limited, specially designated space, you need to know exactly these dimensions.

Studies

It was possible to immediately find out what the width and height of the future acquisition were, and not just its diagonal. It is a simple distance from the opposite top and bottom corners. It is measured in inches, and not in cm, which is familiar to Russian users.

But this is a generally accepted standard for indicating technical specifications, used for a TV receiver, a tablet, a laptop, and even an iPhone. It was introduced in order to unify data on the products of manufacturers from different countries of the world.

How to find out the real parameters of the tablet

Screen dimensions of 10 inches almost always have an aspect ratio of 16:9. This assumes that its height in inches is 4.9 and its width in the same inches is 8.72. The size, if needed in centimeters, can be found in the conversion table or calculated independently using a calculator. It should be remembered that 1 inch = 2.54 centimeters.

Ten inch screen

From here you can find the dimensions of the tablet screen in cm, that is, what they will be:

• width;
• height.

Calculations will show that the width of this structure for visualizing the image (only the screen itself) is 22.14 cm (that is 8.72 inches), and its height is 12.45 cm (4.9 inches).

But there is also a standard aspect ratio that is gradually going out of use. It is believed that the 16:9 aspect ratio of a rectangular screen has a more optimal resolution and is quite safe for vision with constant use. A ten-inch monitor or screen has a height of 6 inches (15.24 cm) and a width of 8 inches (20.32 cm).

Bright colors

Subtleties

Even having at hand a table for converting screen sizes into centimeters from inches, depending on the diagonal, the idea is still approximate. Simply because the frame width is not indicated anywhere in the technical specifications, as if only the screen parameters matter to everyone.

In the children's room

If to install the tablet in a stationary form or to buy a case, you need not the dimensions of the device, but its actual dimensions, you will have to first measure the space in centimeters. Then use a tape measure or soft measuring tape to simply measure along two of the sides. This is enough to recognize all four sides of the rectangle.

The use of a single number to provide information to the consumer - a diagonal in inches - is perhaps a fundamental step towards unification when selling products from different countries.

Slim body

However, this practice makes life easier for sellers of electronic equipment and makes life more difficult for its buyers. And no matter how cheerfully special tables are offered to facilitate the conversion procedure, the need for additional calculations and measurements when purchasing is still present.

How to measure the diagonal of a tablet with a ruler

Device sizes are checked in two ways:

• using a ruler marked in centimeters;

In the first case, the ruler is placed under the diagonal of the device. It is important that it is pressed tightly against the screen. This line can be purchased at your regular office supply store.

You need to download the program from Google Play or Apple Store. Otherwise, the tool will transfer the virus to your tablet. Once installed, click on Display and then on Screen Size.

Where to look in settings

To find out what screen extension is, open Settings. They are marked with a gear icon. If you can't find the app, enter a keyword in the search. To do this, click the magnifying glass icon at the top of the screen.

Once you open Settings, select About Device. At the bottom of the page you will see size information.

Second way. You can also find out the diagonal of your tablet using a special system info droid program, this program can be downloaded from the play market application. If you haven't installed system info droid yet or don't know how to install this application, you can read the instructions on how to download and install system info droid on your tablet. After installing the system info droid program on the tablet, run the system info droid program on the tablet.

After starting the program, click once on the “DISPLAY” item, after which a section will open in which you will see a special Screen Size line, where the diagonal size of your tablet will be indicated in inches and centimeters. Here are simple ways to find out the diagonal of your tablet or phone.

That's all for now, goodbye, good luck! See you at computerhom.ru.

Smartphone diagonal - from large to small in inches

Read what the diagonal of a smartphone is. How to measure it and convert inches to centimeters. Is there a connection between diagonal and resolution? And what is the viewing area of ​​the phone display.

What is the diagonal of a smartphone

The phone screen diagonal is the distance from the bottom left corner to the top right corner. It's quite easy to measure. And anyone with a ruler can do it. The diagonal is indicated in inches. This is because the first devices with screens – televisions – appeared in the USA. And there the so-called “imperial” system of measures was adopted. It is also called English.

How to find out the diagonal of a smartphone in centimeters

To convert inches to centimeters, multiply the diagonal value by 2.54. 1 inch = 2.54 cm or centimeters. For example. If the screen diagonal is 6.2', then in centimeters it will be 6.2 * 2.54 = 15.75 cm.

What is the difference between screen resolution and diagonal

Read more about screen resolution here. In short, the resolution of a smartphone is the number of pixels along the X-axis and Y-axis. For example, 720x1280 pixels.

As you can see, the diagonal tells us about the size of the screen itself. While resolution is how many pixels are on the screen. The more there are, the clearer and more detailed the picture will be. The smaller, the more “grainy” the screen will be.

That is why in the characteristics of smartphones there is still such a thing as pixel density. This is the number of pixels that fit in one inch of a device's screen.

It turns out that the larger the screen diagonal, the higher the resolution should be. This is when the pixel density will be acceptable. For example, a smartphone screen with a diagonal of 5.5 inches and a resolution of 720*1280 pixels will be better in quality than a 6.2-inch screen with the same resolution. This is because in the first case there will be more pixels for every inch of the screen.

What are the diagonals of smartphone screens?

According to Deviceatlas.com, in the first half of 2021, the most popular smartphone diagonals in the hands of users around the world were still 5.5 and 4.7 inches. And this despite the fact that in 2019, a rare manufacturer released models smaller than 5.8 inches onto the market. It seems that in 2021, the first place will be taken by phones with screens from 5.8'.

The maximum smartphone screen size can be considered 6.7 inches. Phones with such screens are also called phablets. Anything larger is already a tablet.

What is the viewing area (viewport) of a smartphone screen

The term “viewport” was coined so that website and application creators could create highly readable and distinguishable elements on any smartphone.

In fact, this is a trick that allows smartphone manufacturers to write beautiful resolution numbers, such as Full HD (1280x1920 pixels), etc. But in fact, in a browser or application in real life, much lower values ​​are used - 414x736. Do you feel the difference?

The viewport makes websites appear differently on mobile devices than they do on a desktop screen. Users don't have to zoom in to see small text and buttons. Thus, the viewing area of ​​a smartphone screen means a resolution at which it will be convenient to view websites or application interfaces.

An example of the relationship between viewing area, resolution and diagonal of iPhone screens:

All smartphone diagonals:

The largest and smallest tablet

In addition to popular sizes, there are prominent representatives of “portable computers” that were created not so much for functionality as for competition in size.
The largest tablet in the world is Ardic Technology London Edition. You cannot take it with you on the road, put it in your bag, in your briefcase, bring it home, pick it up. Its diagonal is 383 inches, and working on such a colossus is, to put it mildly, inconvenient. The giant is equipped with a giant keyboard for typing, but this does not solve the problem.

The world's smallest work tablet is the LEXAND SB5 HD car tablet. Its diagonal is 5 inches. It's not too different from the typical representatives of this genre, but packing technological accretion into a small lump is not so easy. This device is more like a phone in size.
