How to read this
- Pixel density (ppi) is how many pixels fit in one inch. Resolution alone cannot tell you — you have to divide by the diagonal.
- The same 4K is 163 ppi on a 27" monitor and 68 ppi on a 65" TV. That is more than double, but a TV is watched from far away, so it does not matter.
- The distance at which pixels vanish comes from one arcminute, the limit of human sight. Once a pixel looks smaller than that, no eye can find the grid.
- Aspect ratio is width and height reduced to the simplest whole numbers. Modern phones are 19.5:9 or 20:9, so 16:9 video leaves black bars on the sides.
Frequently asked questions
Q. What is the iPhone 8 screen resolution?
750×1334 pixels — 1,000,500 in total, about 1 megapixels, which puts it in the HD class.
Q. What is the pixel density of the iPhone 8?
326 ppi. That is the diagonal in pixels of a 750×1334 grid divided by the 4.7" diagonal of the panel, and it makes each pixel about 78 micrometres across.
Q. How big is the iPhone 8 screen in millimetres?
58.5 mm wide and 104.1 mm tall, worked out from the 4.7" diagonal and the 375:667 aspect ratio. The visible area is roughly 9.4 square inches.
Q. How far away do pixels stop being visible on the iPhone 8?
About 26.8 cm. That is where a pixel subtends less than one arcminute, the limit of human sight — closer than that and the grid starts to show.
Q. What aspect ratio does the iPhone 8 use?
16:9 (exactly 375:667), with the long edge 1.78× the short one. It is taller than it is wide, which suits a device you hold in one hand.
