How to Use the Android Screen Size Calculator
1. Enter screen diagonal size in inches (e.g. 6.7).
2. Enter resolution width and height (e.g. 1080 and 2400).
3. Get exact physical screen width, height, surface area in cm2, and aspect ratio.
2. Enter resolution width and height (e.g. 1080 and 2400).
3. Get exact physical screen width, height, surface area in cm2, and aspect ratio.
Algorithm & Formula Details
Width = Diagonal * cos(arctan(Height / Width)), Height = Diagonal * sin(arctan(Height / Width)).
