YouTube Shorts use the 9:16 vertical ratio at 1080×1920, same as TikTok and Instagram Reels.
YouTube Shorts are 1080 x 1920 pixels, a 9:16 vertical ratio, up to 3 minutes long. Keep text and faces inside the center 4:5 area so captions and buttons don't cover them.

YouTube Shorts specs
YouTube Shorts use 9:16 vertical at 1080×1920. Same dimensions as Instagram Reels and TikTok. Maximum length is 60 seconds; anything longer is treated as a regular YouTube video.
Shorts have their own dedicated player and discovery surface inside the YouTube app, separate from the regular 16:9 video feed. The recommendation algorithm for Shorts is also separate.
Cross-platform cross-posting
A single 1080×1920 9:16 export works on YouTube Shorts, TikTok, Instagram Reels, Facebook Reels, and Snapchat. For creators producing short-form video, one export covers five distribution surfaces.

Shorts safe zone
YouTube's Shorts UI is less invasive than TikTok's, but the right side still has a like / comment / share column, and the bottom has the channel, the title and a row of links. Keep important content centered and away from the bottom 320 pixels.

Frequently asked questions
Is YouTube Shorts the same ratio as TikTok?
Yes. Both use 9:16 at 1080×1920. You can post the same export to both. The audio libraries differ; commercially-licensed audio doesn't always cross over.
Will a long video become a Short on YouTube?
Only if it's vertical (9:16) and under 60 seconds. A 16:9 horizontal video, even if it's 30 seconds, is treated as a regular video, not a Short.
What is an aspect ratio?
Aspect ratio is the relationship between width and height, written as width:height. A 1920×1080 image has a 16:9 aspect ratio because 1920÷120 = 16 and 1080÷120 = 9. The ratio describes the shape of the rectangle, independent of size. A 1280×720 image is also 16:9.
How do I calculate the aspect ratio of an image?
Divide width by height to get the decimal ratio. To get the simplified form, find the greatest common divisor (GCD) of width and height and divide both by it. 1920÷1080 = 1.778, GCD(1920, 1080) = 120, so the ratio is 16:9. The calculator above does this instantly.
Is 1920×1080 a 16:9 aspect ratio?
Yes. 1920÷1080 = 1.778, which equals 16÷9. Full HD video, most monitors, and standard YouTube videos are all 16:9 at 1920×1080.
What aspect ratio is best for Instagram?
Instagram supports four ratios. Square 1:1 at 1080×1080 for feed posts. Portrait 4:5 at 1080×1350 for taller feed posts (recommended for organic reach). Landscape 1.91:1 at 1080×566 for wide posts. Vertical 9:16 at 1080×1920 for Stories and Reels.
What ratio should I use for TikTok?
TikTok uses 9:16 vertical at 1080×1920 pixels. The same applies to Instagram Reels and YouTube Shorts. One vertical export covers all three.
