Question 1

How do I preview a YouTube Short before posting it?

Accepted Answer

You don't need to upload a private draft. Drop your video into this free simulator and it renders inside a 9:16 phone frame with YouTube's Shorts interface overlaid - the right-side action buttons, the title and handle area, and the progress bar - so you can check framing and text legibility before you post.

Question 2

Does this tool upload my video anywhere?

Accepted Answer

No. The simulator is 100% client-side. Your video is opened directly by your browser using a local object URL and is never sent to a server. There is no upload, no account, and no processing queue.

Question 3

What are the YouTube Shorts safe zones?

Accepted Answer

YouTube overlays its own interface on every Short: an action column (like, dislike, comments, share, remix) along the right edge, the channel handle, title, and audio row across the bottom roughly 20% of the frame, and search and camera icons at the top. Anything you place in those regions - faces, captions, watermarks - gets covered. Keep critical content in the central column of the frame.

Question 4

What size and aspect ratio should a YouTube Short be?

Accepted Answer

Shorts are vertical 9:16 video, ideally 1080x1920 pixels, up to 3 minutes long. If you upload a 16:9 video, YouTube displays it fitted with empty space above and below; a center crop of a 16:9 frame keeps only the middle 607-pixel-wide column of a 1080p frame, which is why this simulator shows crop guides for non-9:16 sources.

Question 5

How small is too small for text on a YouTube Short?

Accepted Answer

Shorts are watched on phone screens around 6 inches tall, so text below roughly 2% of the frame height (about 40 pixels on a 1920-pixel-tall Short) becomes hard to read, and low-contrast text disappears against busy footage. This simulator measures your overlay text against the actual frame behind it and warns when it is too small or too low-contrast.

Question 6

Do YouTube Shorts look different on desktop and mobile?

Accepted Answer

Yes. On a phone or tablet, YouTube overlays the action buttons (like, comment, share) directly on the video along the right edge. On desktop (youtube.com), those buttons sit beside the video instead, so they never cover it. This simulator's device switcher shows phone, tablet, and desktop, with mobile as the strict case - if your framing reads on a phone, it reads everywhere.
