Frequently asked

What is the best YouTube video size?
The best standard YouTube video size is 1920 × 1080 pixels, a 16:9 HD video. If your footage was shot in 4K, upload 3840 × 2160 so YouTube can serve a sharper version on large screens.
What is the YouTube video aspect ratio?
Standard YouTube videos use a 16:9 aspect ratio. Vertical videos can be 9:16 and Shorts should use 1080 × 1920, but regular watch-page videos are built around 16:9.
Can I upload 4K video to YouTube?
Yes. Upload 3840 × 2160 for 4K when the source footage was shot at 4K resolution. Upscaling a soft HD file rarely helps because YouTube compression cannot add detail that is not in the source.
What file type should I upload to YouTube?
MP4 with H.264 video and AAC audio is the safest YouTube upload format. MOV and WebM also work, but MP4 is the easiest format to move between editing tools.
What is the maximum YouTube video size?
YouTube accepts uploads up to 256 GB or 12 hours, whichever comes first. Most brand and creator videos should stay much smaller so the upload, processing and review pass faster.
