Overlooking video dimension requirements is one of the biggest mistakes a content creator can make. No one wants their video distorted or awkwardly cropped, right?
If your YouTube Shorts aren’t performing well, one of the first things to check is whether you’re using the correct dimensions and format. Optimizing your videos can boost engagement and make them more visually appealing.
Here’s everything you need to know to make your Shorts stand out.
Key YouTube Shorts Requirements

- Video duration: 15-60 seconds
- File size limit: 10MB
- Orientation: Vertical

- Resolution: 1080x1920 pixels (width x height)
- Aspect ratio: 9:16 (vertical format)

Why Aspect Ratio Matters
The 9:16 format has become the gold standard for short-form mobile content. Here’s why:
It provides a seamless viewing experience no need to rotate your phone.

It aligns with other short-form platforms.
This format has one of the highest engagement rates (5.91%).
YouTube’s algorithm favors it for Shorts content.
Can You Use Other Formats?
Square Format (1:1)
While Shorts are primarily vertical, you can upload square videos (1080x1080 pixels). However, this comes with drawbacks:
- Black bars appear above and below the video.
- The viewing experience is less immersive.
- The algorithm may deprioritize square videos.

Best Practices for Optimizing YouTube Shorts Dimensions

Use gridlines – Keep key elements centered and leave space for captions.
Consider mobile viewing – Think about how your video appears on different devices.
Preview on multiple devices – Ensure everything looks perfect before publishing.
Why Do Shorts Look Different on Some Devices?
Even if you follow all the guidelines, your Shorts may not appear identical on all devices due to:
- Screen size variations – Older or smaller phones might crop the video slightly.
- Device resolution – Higher or lower resolution screens affect display quality.
- OS differences – YouTube’s UI varies slightly between iOS and Android.
Since testing on every device is impractical, your best bet is to keep the most important content in the center and always stick to a 9:16 aspect ratio.
