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 Apple Watch Series 9 (41mm) screen resolution?
352×430 pixels — 151,360 in total, about 0.2 megapixels, which puts it in the 352×430 class.
Q. What is the pixel density of the Apple Watch Series 9 (41mm)?
329 ppi. That is the diagonal in pixels of a 352×430 grid divided by the 1.69" diagonal of the panel, and it makes each pixel about 77.2 micrometres across.
Q. How big is the Apple Watch Series 9 (41mm) screen in millimetres?
27.2 mm wide and 33.2 mm tall, worked out from the 1.69" diagonal and the 176:215 aspect ratio. The visible area is roughly 1.4 square inches.
Q. How far away do pixels stop being visible on the Apple Watch Series 9 (41mm)?
About 26.6 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 Apple Watch Series 9 (41mm) use?
176:215, with the long edge 1.22× the short one. It is taller than it is wide, which suits a device you hold in one hand.
