Questions
YouTube Shorts aspect ratio and size guide
The standard YouTube Shorts aspect ratio is 9:16. A 1080x1920 export is the safest default when you want a Short to fill the full mobile screen without black bars.
If your original clip is horizontal, resize it to 9:16 and crop around the speaker, product, or screen demo. If you need to keep every edge visible, use a contained export and let the vertical frame add bars instead of cutting content off.
