Write the longest version once, then trim for the tightest platform you use. The first line does the most work everywhere, because it is the part people read on a profile preview.

One bio, trimmed to the tightest field
A bio does one job everywhere: tell a stranger who you help and why to follow. Write the full version for the roomiest field you use, then trim for the tightest. The first line matters most, because profile previews and search results show only the start.
