220-character limit. Live counter, profile preview, and search-result preview as you type.
Going over 220 means LinkedIn truncates with an ellipsis. On mobile, the visible cutoff is narrower than 220 chars — the search-result preview above mimics the ~150-char mobile cutoff where your headline becomes "Senior Product Designer · Design Sys…" — so structure the highest-value content (role + specialty) in the first 100 chars.
