Width and height follow the order the maker prints them in; phones are usually listed with the long side first.
- Pixel pitch (computed from PPI; a rectangular estimate, not a measured panel pitch)
- 152.4 um
- Physical size (computed from the rectangle, not the usable area)
- 3.6 by 4.8 in (9.1 by 12.2 cm)
- Aspect ratio (computed)
- 3:4
- Megapixels (computed)
- 0.48
- Looks sharp from (assuming 20/20 vision, one pixel per arcminute)
- 20.6 in and further
- Pixels per degree at an assumed 14 in viewing distance
- 40.7
Every row above is computed here from the stated resolution and the stated diagonal. With w and h in pixels and the diagonal in inches: PPI = sqrt(w^2 + h^2) / diagonal, which here is sqrt(600^2 + 800^2) / 6; pixel pitch = 25.4 mm / PPI; physical size = pixels / PPI, which is the full panel rectangle and not the usable area, so a screen with rounded corners or a notch has less usable area than the size shown; sharpness distance = 1 / (PPI x tan(1/60 degree)), the distance at which one pixel spans one arcminute for 20/20 vision; pixels per degree = 2 x distance x tan(0.5 degree) x PPI at the assumed viewing distance. Values are rounded to two decimals, and to one decimal for the pitch, the sizes in centimeters, the distances, and the pixels per degree.
