What is the size of a 6.5-inch display screen? What are the dimensions of length and width?
The size of a 6.5-inch display screen refers to the diagonal length of the screen being 6.5 inches (approximately 16.51 centimeters). However, its actual length and width dimensions depend on the aspect ratio of the screen.
The most common is the 4:3 ratio screen used in industrial equipment. Taking the 6.5-inch industrial LCD screens of brands such as AUO and Tianma as an example, their display area size is usually:
Width: Approximately 132.48 millimeters.
Height: Approximately 99.36 millimeters.
In addition to this most common specification, there can also be significant differences in length and width dimensions depending on the screen ratio. I have organized several situations into a table for your comparison:
Screen ratio | Typical width (mm) | Typical height (mm) | Typical applications/devices |
4：3 | About 132.48 | About 99.36 | Industrial equipment, old-fashioned displays |
16：9 | About 110.63 | About 62.23 | Mobile phones, portable screens |
Other ratios (such as 1:2) | About 64.54 | About 150.60 | Special vertical screen equipment |
6.5-inch 4:3 screens are mostly industrial grade LCD screens, commonly used in outdoor equipment, vehicles, or industrial computers.
Which specific device do you want to know about the 6.5-inch screen on? If it is a mobile phone, the proportion is usually slender (such as 16:9 or longer), and I can help you calculate its approximate size.
