YouTube Shorts safe zone checker
Load a local file, preview it in a 9:16 frame, and verify that your subject, subtitles, and CTA stay out of the lower interface stack that can crowd Shorts content.
Shorts-safe compositionUI stack marginsLocal preview
Google publishes a conservative central safe rectangle for vertical video ads.
The shaded bands are intentionally conservative. Use them to keep text, faces, and CTA blocks out of likely UI occlusion zones.
Reference guidance: source.
Keep small text inside the bright frame.
Check at multiple timestamps if motion pushes subjects toward the lower UI band.
Use the thirds grid when aligning faces or product shots.
FAQ
Common questions
Does this require an upload?
No. The tool reads a local file in your browser and never writes it to a database or storage bucket.
Is this useful for shorts cutdowns too?
Yes. It is useful for evaluating a 9:16 cutdown before you hand it off to the platform.
Can I use still images?
Yes. You can check a poster frame, thumbnail, or static creative in the same layout.
