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 1600 × 400 px at 4:1. | Mobile views may show a tighter crop or smaller preview. | Centered form header safe area |
| Display behavior | This is a practical production target for predictable editing and export. | 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 1600 × 400 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.
Keep compressed before uploading
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 1600 × 400 px; start with sharp source artwork.
A file outside 4:1 may be cropped, padded, or rejected depending on the upload surface.
Small type often becomes unreadable after mobile scaling and platform compression.

Platform notes
Requirements and crop behavior
Centered form header safe area
Use 1600 × 400 px as a practical working canvas and preview the upload because this placement does not expose a single fixed public pixel spec.
Resize with this presetPixelMeasures labels this as a practical production target because the public platform help does not publish a stable exact pixel table for this placement. Keep important content centered, export in an accepted format, and check the final upload on desktop and mobile before you call the artwork finished.
