How resolution names work

The number before the p is the short side of the frame in pixels; the p means progressive (whole frames, not interlaced). A 16:9 1080p frame is 1920×1080. Turn it vertical and it's 1080×1920: still 1080p, same pixels.

4K in video usually means UHD, 3840×2160, which is exactly four 1080p frames. Cinema DCI 4K is wider, 4096×2160.

Worked example

You filmed 4K wide (3840×2160) and post vertical.

A 9:16 crop of that frame is 1216×2160. Export it at 1080×1920.

1080×1920 = 2,073,600 pixels, the same as 1920×1080: 1.00× 1080p.

Questions

What resolution is 1080p vertical?

1080×1920. Same pixel count as 1920×1080, turned sideways.

What's the best resolution for TikTok, Reels and Shorts?

1080×1920 covers all three. TikTok Studio wants at least 720×1280, Reels at least 720 pixels, and YouTube says Shorts upload at up to 1080p. Meta recommends 1440×2560 for Reels ads.

Is 1440p the same as 2K?

In video it's commonly called 2K, and YouTube labels it 1440p (2k): 2560×1440.

Should I film in 4K for vertical video?

It gives room to crop and reframe, since a 9:16 slice of a 4K wide frame is 1216×2160, still more than 1080×1920. 4K has four times the pixels of 1080p, so files are much bigger.
