Check it in your browser
Use sample values or enter your own. Local file previews stay on your device, and URL previews only load the image URL you provide.
The overlay shows a practical center-safe area, edge caution zone, and duration badge zone.

Step 2
Read the overlays
Review the center-safe area, edge caution area, and lower-right duration badge zone.
Step 3
Move risky content
Keep important text and faces away from tight edges and the duration overlay area.
Reference rules
| Check | Guidance |
|---|---|
| Center-safe area | Keep the most important face, object, or short text inside the middle of the frame. |
| Edge caution zone | Avoid placing essential copy at the outer edges where small surfaces feel cramped. |
| Duration badge | Leave the lower-right area clear because video duration labels often appear there. |
Use cases
Final QA
Check the thumbnail before uploading to avoid hidden text or covered details.
Mobile-first review
Use the overlay to prioritize small-screen readability.
Crop revisions
Decide whether a crop needs more breathing room around the subject.
Result interpretation
Safe placement
Important content stays centered with enough space away from overlays.
Badge conflict
Move text or product details out of the lower-right corner.
Edge tension
Increase margin if key details sit against the frame edge.
Common mistakes
Putting words in the badge zone
The lower-right corner is the easiest place for text to get covered.
Treating guides as exact policy
The overlay is practical design guidance, not a YouTube specification.
Forgetting mobile scale
A safe full-size image can still feel crowded at search-result size.
