Choosing a resolution for YouTube Shorts
1080×1920 is a practical 9:16 editing target, not a universal best resolution or an eligibility requirement. Keep useful source detail and avoid upscaling a low-resolution clip. Shorts also accepts eligible square videos.
Fix it
- Set the video canvas in your editor
Use a vertical or square canvas appropriate to the source. Use your editor to preview an adjustable crop. The linked tool center-crops files up to 100 MB to 1080×1920; do not use it to upscale a low-resolution source.
