With these inches, nothing is clear. It would be much easier if manufacturers indicated the diagonals of manufactured devices in centimeters. So we could determine the diagonal of the screen by eye and decide for ourselves whether it is a lot or a little. But usually the diagonals of TVs, phones, tablets are indicated in inches. Therefore, one often hears from buyers: "Diagonal 7 inches - how much is it?" Let's understand these units of measurement once and for all.
Diagonal 7 inches - how much is it in centimeters?
The easiest way to figure it out is to convert inches to centimeters. Connoisseurs know that one inch is equal to 2.54 centimeters. Based on this, it is easy to calculate how much it is - a diagonal of 7 inches. It will be equal to 17.78 centimeters. Take a regular ruler and see what kind of segment it will be. In the future, if you don’t understand the diagonal, you can already translate inches into centimeters yourself: just multiply the value by 2.5. This can be done even in the mind. If you have a calculator, then multiply by 2.54. It will be more accurate.
TV Diagonal
If you are trying to match a TV, one of the important parameters is its length between two opposite edges - the bottom and the top. This is the diagonal of the TV. Modern models are produced with different diagonals. There are very large TVs with a diagonal of 50 inches or more. But the models that are now the most popular and common have a diagonal of 32 inches. This is the "golden mean" between a huge cinema and a small model for the kitchen.
But as for seven inches, this is extremely small for a TV. Perhaps there are no such models with such a miniature diagonal. However, there are special TVs on the market for cars or for traveling, but such devices have been popular for a long time. Now they have been supplanted by tablets.
Tablet screen size
It is worth noting that most tablets have a screen size of exactly 7 inches. This category usually includes low-cost budget models that are in the greatest demand. They fit perfectly in the hand, making them easy to control. It is not necessary to install a high-resolution matrix in such a diagonal, which reduces the cost of the tablet itself.
The most popular 7 models are:
- Huawei MediaPad.
- PocketBook Surfpad U7.
- 4GoodT700i.
There are also models from the popular Korean manufacturer Samsung. You can list them for a long time, but the fact is that a 7-inch diagonal is ideal for an inexpensive budget tablet.
There is another category - gadgets with a diagonal of 9-10 inches. The manufacturer Apple set the tone for this “fashion”, which in 2010 introduced a tablet with a diagonal of 10″ on the market. And although in fact there are only 9.7″, nobody cares anymore. Many modern gadgets with such a diagonal are positioned precisely as 10-inch tablets.
There are other models with 12-inch screens, but this is already rare.
Mobile phones
If you still can't imagine how much it is - a diagonal of 7 inches, then visualize a smartphone that barely fits in one hand. It is this phone that has approximately the same diagonal. But this is also rare, because most mobile phones are equipped with 5-inch screens. There are also versions with 5.5-inch screens. 6-inch smartphones are rare, and there are very few models with 7-inch matrices.
The popular smartphone iPhone 7 received a diagonal of 4.7 inches (almost 5), and the new Korean flagship Samsung S8 has a 5.8-inch screen. But it is worth recognizing that the matrix of this smartphone is not classical. I even had to introduce a new term Infinity Display to explain the large diagonal.
Conclusion
Remember the number "2.54". To understand how much it is - a diagonal of 7 inches, just multiplyvalue by 2.54 or at least 2.5 for higher accuracy.
