Email Signature Size Guide (Gmail + Outlook)

Logo sizing

• Use a logo width around 80–120px in most layouts.
• Keep the height proportional so the signature doesn’t become too tall.
• Prefer a logo with transparent background and clear edges.

Spacing + layout

Avoid stacking too many elements. Keep contact lines short, use subtle separators, and ensure the signature doesn’t overpower your email content.

Font sizing

• Body text: 10–13px
• Name/title: slightly larger for scan-readability
• Test on both desktop and mobile
