You may have heard of 1080p / 1440p if not 4k (especially tvs or televisions) and so on, but I decided to lay it out to make it easier or as easy for people to understand.
480 x 360 ---------- .48k ------------ 360p
640 x 480 ---------- .64k ------------ 480p
1280 x 720 -------- 1.28k ----------- 720p
1920 x 1080 ------ 1.92k (2k) ----- 1080p ----- not true 2k
2560 x 1440 ------ 2.56k (2.5k) -- 1440p ----- true 2.5k
3840 x 2160 ------ 3.84k (4k) ---- 2160p ----- not true 4k
5120 x 2880 ----- 5.12k (5k) ----- 2880p ----- true 5k
7680 x 4320 ----- 7.68k (8k) ----- 4320p ----- 7.5k or true 7.5k to me personally, but definitely not true 8k if you were to put it in the 8k realm...
"True" is another term as well... 3840 x 2160 is technically (3.84k and not 4k so it's "truly" not "4k" at that point). 3.84k is very common though and rounds up to 4k.
4096 x 2160 - 4k (over 4k or true 4k not 3.84k or under 4k) - 2160p
True 4k is 4096 x 2160 to me personally.
7680 x 4320 - to me this is 7.5k not 8k since it rounds down closer to 7.5k than up to 8k (over / under - 7.75k - 7,750)
True 8k would be 8,000 or above 8,000.
Left side is where you get 2k, 2.5k, 4k, 5k, and/or 8k.
Right side is where you get 1080p, 1440p, 2160p, 2880p, and/or 4320p.
2k (1080p)
2.5k (1440p)
4k (2160p)
5k (2880p)
8k (4320p)
This does not include wide screens or it would be basically a 3.5k (widescreen) type situation going or something else like that.
Let me know if I got something wrong. Also it's never perfect (basically), but this shows a wide range at least to me personally.
I should let the 7.5k go though before I go into full geek if not full nerd or both being... Grandmaster G/N (Geek / Nerd) combo...
It's just not worth it...

It's "True 7.5k" (7680x4320) to me though.
