#FAQ
How is PPI calculated? ▾
PPI (pixels per inch) is calculated as the diagonal resolution divided by the diagonal size in inches: PPI = √(width² + height²) / diagonal inches.
How are megapixels calculated? ▾
Megapixels equal the total number of pixels (width × height) divided by 1,000,000. For example, a 1920×1080 display has about 2.07 megapixels.
