The safe zone is the area not covered by YouTube UI. Avoid the bottom-right corner (timestamp) and very bottom edge (progress bar).

Yes. Shorter durations produce a narrower box (~44px) while longer formats like 1:23:45 produce a wider box (~62px).

How do I make my thumbnail text readable on mobile?

Use large, bold text with high contrast. Test with our Blur Test - if readable through 3px blur, it works on mobile.

What size should my YouTube thumbnail be?

1280x720 pixels (16:9) minimum 640px wide, under 2MB in JPG, GIF, or PNG format.
