Now the screen of smart phones is getting larger and larger, and many netizens want to change a phone with a larger screen. Among them, there may be "how much larger a 5-inch screen phone will be than my current phone ？ ”Or the question "Who is bigger on the 3:2 4-inch screen or 16:9 4-inch screen.

Different mobile phones have different resolutions. for example iPhone 4 /4S resolution is 960x640 (3:2), Galaxy Note resolution is 1280x800 (16:10), Lumia 900 resolution is 800x480 (5:3), Galaxy Note II resolution is 1280x720 (16:9), etc. The commonly known "X-inch screen" refers to the diagonal length of the screen. Even if the diagonal length is the same, the screen area will be different under different length width ratios.

The following figure visually shows the size of the above four common screen scales under the same size (diagonal length):

It can be seen that when the diagonal length is the same, the 3:2 resolution screen is the largest and the 16:9 resolution screen is the smallest. This is why many netizens thought that the 3.7-inch Defy (16:9) was not as large as the 3.5-inch iPhone 4/4S (3:2) screen. Let's calculate:

IPhone 4/4S: 3.54 inch=89.9mm, length width ratio is 3:2, calculated by Pythagorean theorem, length=74.8mm, width=49.9mm, screen area=3731mm2;

Defy: 3.7 inch=94.0mm, length width ratio is about 16:9, calculated by Pythagorean theorem, length=81.9mm, width=46mm, screen area=3772mm2.

From the calculation results, the Defy size of the 3.7-inch screen is almost the same as the so-called 3.5-inch iPhone 4/4S, and because the Defy screen is narrower, people will feel that it is smaller from the visual experience. It can be seen that if you care more about the screen area, when choosing a mobile phone, you should not only see the size of the screen represented by the diagonal length, but also see the resolution of the screen.

The minicomputer also calculated the screen display area of common resolutions at 4.0-5.5 inches, as shown in the following table (from the table, we can also see why the 5.5 inch Galaxy Note II screen looks the same size as the 5.3 inch Galaxy Note), for your reference:

*Note 1: The resolution of iPhone 5 is 1136x640, not exactly equal to 16:9, but very close;

Note 2: Meizu MX2 uses a 4.35 inch screen, known as 4.4 inch.
