- Keep key text away from the bottom-right timer area.
- Vertical video thumbnails may appear differently in some YouTube mobile surfaces.
16:9 / 4:5 note: the blue center reference shows a conservative 4:5 mobile crop area for vertical-video surfaces. Build important text inside the center, away from the lower-right timer badge.
How to use this result
Start with the target surface: a printed size, a platform canvas, a marketplace image requirement, or a safe-zone overlay. Enter the real pixel dimensions or upload a local image when the tool supports it, then compare the result with the recommended size, ratio, file-size limit, and source note.
Use the copied output as a production checklist rather than as an approval guarantee. The calculator checks measurable dimensions and ratios, while final acceptance can still depend on compression, color, account settings, crop previews, platform policy, or printer-specific export instructions.
FAQ
