To illustrate how this works, let’s calculate the PPI for a Full HD (1920 x 1080) screen with a diagonal size of 15.6 inches.
- Calculate Width² + Height²
- Width² = 1920² = 3,686,400
- Height² = 1080² = 1,166,400
-
Total = 3,686,400 + 1,166,400 = 4,852,800
-
Calculate Diagonal
-
Diagonal = 15.6 inches
-
Apply formula
- PPI = √4,852,800 / 15.6 ≈ 197.5 PPI
Thus, a 15.6-inch laptop with Full HD resolution has approximately 197 PPI, providing a clear and vibrant display.
