Design tips for GitHub social preview / OG card on Twitter unfurl
- •Anchor to the center. GitHub social preview / OG card crops differently on Twitter unfurl 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 Twitter unfurl — design around them, not under them.
- •Export at 2×. Save at 2560×1280px so the image looks crisp on retina Twitter unfurl screens.
- •Audit before posting. A 90-second Better Header audit shows you exactly what gets cut off on Twitter unfurl and every other supported device.
