9:16 Aspect Ratio
A 9:16 frame is 9 units wide for every 16 units high. Common sizes include 720 x 1280 and 1080 x 1920 pixels. It is the portrait version of 16:9 and fills a vertically held phone screen, which makes it useful for full-screen vertical photos and video.

Nine width units correspond to sixteen height units, a decimal ratio of 0.5625. Multiply width by 16/9 to calculate the exact vertical canvas height.
How it compares
A 9:16 frame is taller than 2:3, 3:4, or 4:5. It shows less content at the sides, so keep faces, captions, and important details away from interface overlays.
Common uses
- Full-screen vertical video viewed on a phone.
- Stories, tutorials, and demonstrations with the main subject near the center.
Fit, Crop, and Pad

Fill the framePad
Add background
Cropping a 16:9 landscape video to 9:16 removes most of both sides, so a centered crop can miss an off-center subject. Fit keeps the full video but leaves large areas above and below. Pad fills those areas with a background.

Calculate the missing side
height = width × 16 / 9width = height × 9 / 16
For a 1080 px width, height = 1080 x 16 / 9 = 1920 px. For a 1280 px height, width = 1280 x 9 / 16 = 720 px.
