If you're preparing a vertical video for YouTube Shorts, start by deciding on the frame shape. The dimensions control how much of the image fits in the player, while resolution controls how many pixels make up that frame.
What size should a YouTube Short be?
A common full-height vertical canvas is 1080 × 1920 pixels, which has a 9:16 aspect ratio. It is a useful export starting point for vertical short-form video, but it is not a guarantee that every upload will look identical on every device or placement.
| Setting | Common starting point | What it means |
|---|---|---|
| Aspect ratio | 9:16 | Tall, portrait frame |
| Resolution | 1080 × 1920 px | Width and height in pixels |
| Orientation | Vertical | Height is greater than width |
Remember: aspect ratio and resolution are different. A 720 × 1280 frame is also 9:16; it simply contains fewer pixels than a 1080 × 1920 frame.
How to set up a 9:16 frame
- Open your editing project settings and choose a custom or vertical sequence.
- Set the width to 1080 and height to 1920 pixels if that fits your workflow and source footage.
- Preview the full frame, not only the crop shown in your editing viewer.
- Keep important captions and visual details away from the extreme edges and areas where platform controls may appear.
- Export a short test and watch it on a phone before using the settings for a batch of videos.
Some editors ask for width and height, others offer a preset, and some automatically inherit the source footage's dimensions. Check your project settings rather than assuming that a vertical-looking preview means the export is vertical.
How to check your dimensions
Use the Cliperfly aspect ratio calculator to check the frame shape from a video's pixel dimensions. Select the 9:16 preset, or enter your own width and height to see the simplified ratio.
Common mistakes to avoid
- Stretching footage: changing dimensions without preserving the ratio can distort faces and objects.
- Confusing crop with resize: resizing changes the dimensions; cropping removes part of the visible image.
- Placing captions too close to the edge: interface elements and different screens can make edge content harder to read.
- Assuming the same settings are perfect forever: platform and editor recommendations can change, so verify the latest official guidance before a large publishing run.
Frequently asked questions
Is 1080 × 1920 the same as 9:16?
Yes. 1080 divided by 1920 simplifies to 9 divided by 16, so those dimensions have a 9:16 ratio.
Can I upload a video with a different resolution?
Video platforms accept a range of formats, but processing and presentation can vary. Choose dimensions that suit your footage and check YouTube's current official upload guidance if you need a specific technical requirement.
Will changing aspect ratio improve video quality?
No. Aspect ratio describes shape. Perceived quality also depends on source footage, resolution, bitrate, compression, lighting, and other production choices.
