X logo size: 400px profile after rebrand
Master the 400 pixel X profile size with bold black marks that survive round crops and dark mode.
Black X that reads tiny
X displays profiles at 400 by 400 pixels but shrinks them to 48 pixels in timelines. The black X needs 20 pixel clear margins and stark contrast to stay legible on white feeds and dark mode alike.

Headers and dark mode tricks
Headers span 1500 by 500 pixels with center safe zones of 1260 by 280 for laptops. Pure black marks vanish in dark mode, so add white outlines 8 pixels thick or place art on light gray.
Keep animated versions under 5 seconds and static fallbacks at 400, 800 and 1200 pixels. Brands refreshing within 18 months of the 2023 rebrand kept 35 percent more followers than those using old bird art.
