Why the Safe Zone Matters
YouTube renders the video duration (e.g. "12:34") as a small dark badge fixed to the bottom-right corner of every thumbnail, on every placement, on every device. If your text, logo, or a face is positioned there, it gets covered — permanently, with no way to opt out.
On Shorts and mobile feeds, additional UI elements (channel avatar, like button, progress bar) can overlap other edges too.
The Safe Zone Boundaries
| Zone | Pixels (on 1280×720) | Risk |
|---|---|---|
| Bottom-right corner | ~160×40 px reserved | Duration badge always covers this |
| Outer 10% border | ~128px from each edge | Cropped on some mobile/TV displays |
| Center 70% | 896 × 504 px (centered) | Always visible — design here |
Practical Safe Zone Rules
- Never place text in the bottom-right 15% of the frame — the duration badge will cover it.
- Keep faces and key subjects within the center 70% of the canvas.
- Leave a margin from all four edges — some TV and mobile displays crop the outer 5–10%.
- Test at actual size: view your design at 168×94px before publishing to catch any overlap issues.
Visual Safe Zone Template
Designers commonly overlay a guide grid: draw a rectangle from 10% inset on all sides, with an additional exclusion zone in the bottom-right corner sized roughly 160×40px (scaled to your canvas). Anything inside this region is guaranteed visible; anything outside risks being cropped or covered.

Common Safe Zone Mistakes
- Placing a logo watermark in the bottom-right (gets hidden by duration badge)
- Putting critical text flush against any edge (risks mobile cropping)
- Centering a face exactly in the middle without accounting for text space
