YouTube Video Size

The YouTube player is 16:9, so 16:9 video fills it without bars. 1920 × 1080 (1080p) is the everyday standard, and YouTube also accepts 1440p, 4K (3840 × 2160) and up to 8K (7680 × 4320).

Safe zone and tips

Making a 16:9 image from a phone photo

A typical 12-megapixel phone photo is 4032 × 3024. The largest 16:9 area you can cut from it is 4032 × 2268 pixels: crop to that, then scale it down to 1920 × 1080. Cropping first and scaling second keeps everything in proportion.

Frequently asked questions

What is the best size for YouTube videos?

Use 1920 × 1080 (1080p (recommended), 16:9), 1280 × 720 (720p, 16:9), 2560 × 1440 (1440p, 16:9), and 3840 × 2160 (4K (2160p), 16:9). The first one is the safest default.

Which aspect ratio should YouTube videos use?

16:9. Crop to the ratio first and then scale to the size in pixels, so nothing is stretched or cut off unexpectedly.

What is the smallest resolution YouTube lists?

YouTube’s standard sizes go down to 426 × 240 (240p). That looks blurry on today’s screens, so 1280 × 720 is a sensible minimum for new uploads and 1920 × 1080 is better.
