A 4K video frame (3840 x 2160, about 8.3 MP) meets 100 pixels per inch for 27 of the 34 listed sizes, the largest by area being 18 x 36 in; 24 x 36 in is out because its short side needs 2,400 pixels and the frame has 2,160. An 8K frame (7680 x 4320) reaches 33 sizes, up to 40 x 60 in.
Video and screen frames against 8 x 12, 16 x 24 and 24 x 36 in.
Frame sizes, from the sources
DJI's Osmo Pocket 3 page publishes 4K at 3840 x 2160, 2.7K at 2688 x 1512, 1080p at 1920 x 1080 and a 3K 1:1 size of 3072 x 3072. Wikipedia gives 4K as 3840 x 2160 for digital television and 4096 x 2160 for digital cinematography, about 8.3 megapixels for 3840 x 2160, and 8K UHD as 7680 x 4320, the highest size in Rec. 2020. Apple's pages give the iPhone 16 and 17 screens as 2556 x 1179 and 2622 x 1206 pixels and say you can take 8MP still photos while recording 4K video.
Each frame against the listed sizes
The rule is the same as on the phone pages. The screen-capture rows assume a screenshot has the display's pixel size, because Apple's pages give display pixels only. Because video is wider than most prints, the short side decides: a 2,160-pixel short side meets 100 ppi up to 21.6 in on that side.

Worked example
A 4K frame is 3840 x 2160. A 16 x 24 in print needs 1,600 x 2,400, and 2,160 and 3,840 are both above that, so it fits. A 20 x 30 in print needs 2,000 x 3,000, which also fits. A 24 x 36 in print needs 2,400 on the short side and the frame has 2,160, so it does not.
The frame size is the pixels in the video, not the sharpness: compression and motion blur apply. Apple's note that a still can be taken while recording 4K at 8MP suggests a still is saved separately from the video frames; check the file you will print.
