हल किया गया उदाहरण
1920x1080 display, 24-inch diagonal.
- 01Diagonal pixels = sqrt(1920² + 1080²) = 2203
- 02PPI = 2203 / 24 = 91.8 PPI
- 03Pixel size = 25.4 / 91.8 = 0.277 mm
अक्सर पूछे जाने वाले प्रश्न
What PPI is considered "Retina"?
Apple defines Retina as a PPI where individual pixels are indiscernible at typical viewing distance. For phones (held close), this is ~326+ PPI. For laptops (~18 inches away), ~220+ PPI. For desktops (24+ inches), ~110+ PPI.
Is higher PPI always better?
Higher PPI means sharper text and images but also requires more GPU power and makes UI elements smaller unless scaled. For most desktop use, 100-163 PPI is comfortable.
