Nothing is clear with these inches. It would be much simpler 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 televisions, phones, tablets are indicated exactly in inches. Therefore, one often hears from customers: "Diagonal of 7 inches - how much is it?" Let's look at these units once and for all.
Diagonal 7 inches - how many centimeters is it?
The easiest way to figure it out is to convert inches to centimeters. Connoisseurs know that one inch equals 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 an ordinary ruler and see what kind of segment it will be. In the future, if you do not understand the diagonal, you can already convert the inches to centimeters yourself: just multiply the value by 2.5. This can be done even in the mind. If there is a calculator, then multiply by 2.54. It will be more accurate.
TV diagonal
If you are trying to pick up a TV, then one of the important parameters is its length between two opposite edges - lower and upper. This is the diagonal of the TV. Modern models are available with different diagonals. There are very large televisions with a diagonal of 50 or more inches. But the models, which are now the most popular and common, have a diagonal of 32 inches. This is the middle ground between a huge movie theater and a small model for the kitchen.
But as for the seven inches, this is extremely small for the TV. Perhaps there are no such models with such a miniature diagonal. However, the market has special TVs for cars or for traveling, but such devices have been popular for a long time. Now they are replaced by tablets.
Tablet Screen Size
It is worth noting that most tablets have a screen diagonal of exactly 7 inches. This category usually includes low-cost budget models that are in greatest demand. They fit perfectly in the hand, which makes them easy to control. It is not necessary to install a matrix with a high resolution in such a diagonal, which reduces the cost of the tablet itself.
The most popular 7-inch models are:
- Huawei MediaPad.
- PocketBook Surfpad U7.
- 4Good T700i.
There are also models from the popular Korean manufacturer Samsung. You can list them for a long time, but the fact is that the 7-inch diagonal is ideal for an inexpensive budget tablet.
There is another category - gadgets with a diagonal of 9-10 inches. Set the tone for this "fashion" manufacturer Apple, which in 2010 introduced on the market a tablet with a diagonal of 10 ″. And although in fact there is only 9.7 ″, this does not bother anyone. 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 a rarity.
Mobile phones
If you still can’t imagine how much it is - a diagonal of 7 inches, then visualize a smartphone that can barely fit in one hand. Such a phone has approximately such a diagonal. But this is also a rarity, because most mobile phones are equipped with 5-inch screens. There are also versions with screens with a diagonal of 5.5 inches. Rarely there are 6-inch smartphones, and models with matrices of 7 inches are generally units.
The popular iPhone 7 smartphone got 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 classic. I even had to introduce the new term Infinity Display to explain the large diagonal.
Conclusion
Remember the number "2.54". To understand how much this is a diagonal of 7 inches, just multiply the value by 2.54, or at least 2.5, for higher accuracy.
