2160
2160 is the vertical resolution of 4K ultra-high-definition video.

Where 2160 fits
Why 2160 is special
It is exactly twice 1080 in each direction, so a 4K frame holds four 1080p frames. The '4K' name counts horizontal pixels — about 3,840 — while the older names counted vertical lines, which is why the two conventions disagree.

Related numbers & connections
4K is exactly twice 1080p in each direction, so one 4K frame contains four 1080p frames. The naming conventions count different axes, which is why the numbers seem inconsistent.
View 1080 →Technology & computing
1080p counts horizontal lines; 4K counts vertical columns, roughly 3,840 of them. The same jump in resolution is therefore described by a smaller number in one convention and a larger one in the other, which is why the names are confusing.
