Email Header Dimensions
Reference canvas: 600 × 200 pixels (3:1)
A 600 × 200 pixel email header is a display-size example for a 600-pixel-wide template. A 1200 × 400 source can supply extra detail on high-density screens. The template, not an email-wide rule, determines the final crop and width.

Keep essential content in HTML
Give the image useful alt text and an explicit display width. Include headings, offers, and actions as live HTML so the message still works when images are blocked. Test the actual clients and template at narrow widths.
How to check the export
Check the final file’s pixel dimensions and crop, then preview it where it will be used. Compare text, edges, and subject detail at the displayed size. Keep an original so another crop or a less compressed export can be made without starting from the delivery copy.
Quick Tips
- → Keep an editable original and export a separate delivery copy.
- → Check text and subject framing at the actual display size.
- → Compare the final published result after any platform processing.
Frequently Asked Questions
Is this the only usable size?
No. This page gives a specific design size or an attributed platform recommendation. Other crops and placements can have different requirements; consult the linked reference for the destination.
Will changing DPI make this image sharper online?
Changing DPI metadata alone does not add pixels. For web display, check the source pixel dimensions, rendered CSS size, device pixel density, and compression quality.
