Design tips for Email signature banner on Gmail mobile
- •Anchor to the center. Email signature banner crops differently on Gmail mobile than on desktop — centering keeps your headline, logo, or CTA visible everywhere.
- •Avoid the chrome. Status bar, Dynamic Island, and profile-picture overlays are fixed positions on Gmail mobile — design around them, not under them.
- •Export at 2×. Save at 1200×240px so the image looks crisp on retina Gmail mobile screens.
- •Audit before posting. A 90-second Better Header audit shows you exactly what gets cut off on Gmail mobile and every other supported device.
