Design tips for Substack publication header on Desktop (1440p)
- •Anchor to the center. Substack publication header crops differently on Desktop (1440p) 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 Desktop (1440p) — design around them, not under them.
- •Export at 2×. Save at 2200×800px so the image looks crisp on retina Desktop (1440p) screens.
- •Audit before posting. A 90-second Better Header audit shows you exactly what gets cut off on Desktop (1440p) and every other supported device.
