Vertical video
Vertical video is video filmed and displayed in portrait orientation, usually with a 9:16 aspect ratio, so it fills a phone screen held upright. It is the standard format for TikTok, Instagram Reels, YouTube Shorts and Stories. Vertical video avoids black bars on phones, unlike horizontal 16:9 video viewed in portrait mode.
Why it matters
Most phone viewing happens with the device held upright, so vertical video fills the screen and holds attention. Horizontal video on a phone shrinks to a small strip. For short video and microdrama apps, vertical is not optional, and producing for it changes how teams shoot, edit and frame every shot.
How it works
- Video is shot or edited in portrait shape, usually 1080 x 1920 pixels for a 9:16 ratio.
- The file stores that shape so players know it is taller than it is wide.
- Mobile apps play it full screen when the phone is upright.
- For horizontal footage, editors crop or reframe the key subject into a vertical frame.
What is the best resolution for vertical video?
The most common choice for vertical video is 1080 x 1920 pixels, a 9:16 ratio in Full HD. It fills most phone screens and is widely accepted by short video platforms. Some creators shoot at 2160 x 3840 (vertical 4K) to allow cropping, then export at 1080 x 1920 to keep files small.
Is vertical video 9:16 or 4:5?
Vertical video is usually 9:16, which fills a whole phone screen. 4:5 is a slightly tall format often used for feed posts, because it takes up more space than a square without covering the full screen. Choose 9:16 for full-screen stories and short clips, and 4:5 for scrolling feed posts that sit between other content.
Where it's used
Short video apps and microdrama services build everything around vertical video because people hold phones upright. News publishers reframe horizontal footage into vertical clips for mobile audiences.
By the numbers
- YouTube treats only square or vertical videos of up to 180 seconds as Shorts; wider formats are not classified as Shorts. (Understand three-minute YouTube Shorts (YouTube Help))
