Design tips for Substack publication header on iPhone 16 Pro
- •Anchor to the center. Substack publication header crops differently on iPhone 16 Pro 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 iPhone 16 Pro — design around them, not under them.
- •Export at 2×. Save at 2200×800px so the image looks crisp on retina iPhone 16 Pro screens.
- •Audit before posting. A 90-second Better Header audit shows you exactly what gets cut off on iPhone 16 Pro and every other supported device.
