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 Galaxy Tab S9 screen resolution?
1600×2560 pixels — 4,096,000 in total, about 4.1 megapixels, which puts it in the QHD class.
Q. What is the pixel density of the Galaxy Tab S9?
274 ppi. That is the diagonal in pixels of a 1600×2560 grid divided by the 11" diagonal of the panel, and it makes each pixel about 92.6 micrometres across.
Q. How big is the Galaxy Tab S9 screen in millimetres?
148.1 mm wide and 236.9 mm tall, worked out from the 11" diagonal and the 5:8 aspect ratio. The visible area is roughly 54.4 square inches.
Q. How far away do pixels stop being visible on the Galaxy Tab S9?
About 31.8 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 Galaxy Tab S9 use?
16:10 (exactly 5:8), with the long edge 1.6× the short one. It is taller than it is wide, which suits a device you hold in one hand.
