How to Resize a Video for YouTube Shorts?
Sized Right for Every YouTube Format
Resize for All YouTube Formats
For Shorts, that’s 1080×1920px at a 9:16 aspect ratio, vertical, full-screen, and algorithm-friendly. For standard uploads, 1920×1080px (16:9) is the go-to. Dadan handles both, including the reframing when you’re converting horizontal footage into a vertical Short.
YouTube Quality Optimization
YouTube compresses every upload. Dadan exports videos with settings that give YouTube’s processing the least reason to degrade your video. The cleaner the source, the sharper the result on screen.
Real Time Preview
Preview the resized frame before export so text, faces, products, and key motion stay visible in the final cut.
