What is the size of a 5.7-inch display screen? What are the dimensions of length and width?
The size of a 5.7-inch display screen also depends on the aspect ratio of the screen. This size refers to the diagonal length of the screen, which is approximately 14.5 centimeters.
There are two common specifications for the current mainstream 5.7-inch screen. Below are their detailed data, which you can refer to based on your own device situation.
Comparison of two mainstream specifications
Screen ratio | Common application scenarios | Display area width | Display area height |
4: 3 %ratio | Industrial equipment, medical instruments, old portable screens | About 11.5 centimeters | About 8.6 centimeters |
16：9 %ratio | Some old smartphones and portable displays | About 12.6 centimeters | About 7.1 centimeters |
For example, if you are asking about a 5.7-inch display screen on an industrial device, it is likely to have a 4:3 ratio and a length and width of approximately 11.5cm x 8.6cm. If you are asking about the screen of an old smartphone, it is likely to have a 16:9 ratio and dimensions of approximately 12.6cm x 7.1cm.
How to make an accurate judgment?
You can quickly confirm through the following methods:
Observing appearance: The screen looks almost square, which is 4:3; It looks quite slender, at 16:9.
Query parameters: The most accurate method is to search for "screen resolution" online based on your device model.
If the resolution is 640 × 480 (VGA) or 320 × 240 (QVGA), then it is a 4:3 aspect ratio screen.
If the resolution is 854 × 480 (FWVGA) or 1280 × 720 (HD), then it is a 16:9 aspect ratio screen.
I hope this information is helpful to you! If you can tell me which device the 5.7-inch display screen is used on, or know its resolution, I can help you make more accurate recommendations.
