9:16 is the frame for phone video, and 1080 × 1920 matches it exactly. If the clip is meant to fill a phone, shoot tall from the start instead of cropping a sideways take.

9:16 is the tall frame for vertical video, the shape that fills a phone held upright. A 1080 × 1920 file matches it exactly. At 6.1 inches on the diagonal, the frame measures 3.0 × 5.3 inches (7.6 × 13.5 cm).
How this is calculated
As of November 2026, Google's ads help says vertical videos with a 9:16 aspect ratio are "best suited for the Shorts format." YouTube's upload help says you can upload "a short-form vertical video as a Short," and its Shorts file requirements say "With a square or vertical aspect ratio."
Divide 1080 by 1920 and you get 0.5625, the exact value for 9:16. A 720 × 1280 file has the same shape at a smaller size.
Put the two frames at the same height and the 16:9 one is 216% wider. That's why a vertical clip on a TV leaves bars on both sides.
Verdict
Choose 9:16 when the video is made to be watched upright on a phone. At 6.1 inches on the diagonal, the frame is 3.0 inches (7.6 cm) wide and 5.3 inches (13.5 cm) tall. On a 16:9 screen, the bars take up the rest of the width, so the picture looks small. Export at 1080 × 1920 so the file matches the frame without cropping or padding.
