How big is a six-inch mobile phone?

Actually, you can do the math yourself.

1 inch ≈2.54 cm

6 inches = 15.24 cm

The general mobile phone screen is 16: 9.

So if the length is x, 9X/ 16:

x？ +(9X/ 16)？ =( 15.24)?

X ≈ 13cm

Therefore, if the screen ratio of a 6-inch mobile phone is 16: 9, its length is about 13 cm and its width is about 7 cm.

This is just the length and width of the screen. If you count the border, it should be a little bigger.
