Formula
How to calculate this size
Export at the recommended pixel canvas before upload or handoff.
Reduce width and height by their greatest common divisor.
Use fit for no crop, fill or center crop for exact coverage, or pad when borders are acceptable.
Desktop and mobile
How this image displays
Use the upload size as the source canvas, then keep important content inside the safest visible area.
| Item | Desktop | Mobile | Text/logo placement |
|---|---|---|---|
| Upload size | Start from 3840 × 2160 px at 16:9. | Mobile views may show a tighter crop or smaller preview. | Keep the important subject centered. |
| Display behavior | This follows the current official or platform-published recommendation. | Preview after upload because responsive platform surfaces can resize, pad, or crop artwork. | Avoid edge-dependent text, tiny logos, and important details near corners. |
Export checklist
Before you upload
Export the canvas at 3840 × 2160 px before uploading.
sRGB is the safest color profile for consistent web and app display.
Use JPG for photos and PNG for crisp logo, type, or flat artwork when the platform accepts it.
Mobile: 2 MB for video thumbnails. Desktop: 50 MB.
Review desktop and mobile previews so cropping, padding, and compression do not hide important content.
Common mistakes
Avoid these image problems
Responsive previews, masks, and thumbnails can crop or soften edge content.
Do not upscale a small file to 3840 × 2160 px; start with sharp source artwork.
A file outside 16:9 may be cropped, padded, or rejected depending on the upload surface.
Small type often becomes unreadable after mobile scaling and platform compression.
