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 MacBook Air 15" (M3) screen resolution?
2880×1864 pixels — 5,368,320 in total, about 5.4 megapixels, which puts it in the 2.8K class.
Q. What is the pixel density of the MacBook Air 15" (M3)?
224 ppi. That is the diagonal in pixels of a 2880×1864 grid divided by the 15.3" diagonal of the panel, and it makes each pixel about 113.3 micrometres across.
Q. How big is the MacBook Air 15" (M3) screen in millimetres?
326.2 mm wide and 211.2 mm tall, worked out from the 15.3" diagonal and the 360:233 aspect ratio. The visible area is roughly 106.8 square inches.
Q. How far away do pixels stop being visible on the MacBook Air 15" (M3)?
About 38.9 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 MacBook Air 15" (M3) use?
360:233, with the long edge 1.55× the short one. It is wider than it is tall, which suits video and side-by-side documents.
