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 S23 Ultra screen resolution?
1440×3088 pixels — 4,446,720 in total, about 4.4 megapixels, which puts it in the QHD+ class.
Q. What is the pixel density of the Galaxy S23 Ultra?
501 ppi. That is the diagonal in pixels of a 1440×3088 grid divided by the 6.8" diagonal of the panel, and it makes each pixel about 50.7 micrometres across.
Q. How big is the Galaxy S23 Ultra screen in millimetres?
73 mm wide and 156.5 mm tall, worked out from the 6.8" diagonal and the 90:193 aspect ratio. The visible area is roughly 17.7 square inches.
Q. How far away do pixels stop being visible on the Galaxy S23 Ultra?
About 17.4 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 S23 Ultra use?
19.5:9 (exactly 90:193), with the long edge 2.14× the short one. It is taller than it is wide, which suits a device you hold in one hand.
