PPI Calculator
Enter horizontal and vertical resolutions plus measured diagonal inches. Output includes PPI (pixel density), aspect ratio approximation, megapixels, and dot pitch in millimeters.
- PPI
- 108.79
- Dot pitch
- 0.233 mm
- Aspect (simplified)
- 16:9
- Megapixels
- 3.69 MP
How to use
- Use panel marketing diagonal if bezels negligible; tighter accuracy comes from datasheet active area.
FAQ
Subpixel OLED layouts?
PPI here counts logical RGB pixels—not Pentile sub-pixel geometry differences.
Overview
Analytic geometry only — no uploads. PPI equals hypotenuse of pixel width and height counts divided by physical diagonal measurement.
