The 9:16 aspect ratio is the vertical video standard, essentially 16:9 rotated 90 degrees. It has become the dominant format for mobile-first content on platforms like TikTok, Instagram Reels, YouTube Shorts, and Stories. This tall, portrait orientation fills the entire screen on smartphones held vertically.
For TikTok, Instagram Reels, and YouTube Shorts, use 1080 x 1920 pixels. This Full HD vertical resolution is the standard across all major platforms and ensures your content looks crisp on all devices.

Yes! 9:16 is simply 16:9 turned on its side. If you have a 1920x1080 (16:9) video, rotating it gives you a 1080x1920 (9:16) frame. The math is identical, just with width and height swapped.
Most people hold their phones vertically most of the time. Vertical video fills the entire screen without requiring rotation, creating a more immersive, full-screen experience. Studies show vertical videos have higher completion rates on mobile.
Yes, but you'll lose significant content. You can either crop (losing the sides), add blur/color bars on top and bottom, or use AI tools to expand the frame. The best approach depends on your content.
Most platforms accept 24-60fps. TikTok and Instagram Reels work best at 30fps. YouTube Shorts supports up to 60fps. Higher frame rates (60fps) are good for action content but increase file size.
