TikTok keeps line breaks exactly as you type them, so a bio that looks tidy in a notes app can wrap differently once it's live — checking it here first catches that before you save changes on your actual profile. At 80 characters, shortened link text and hashtags often need deliberate trimming to fit.
At 80 characters, there's rarely room for more than a short line or two — a name, a niche, maybe an emoji or a call to action — so it's worth treating the space as a headline rather than trying to fit a full introduction, which is exactly what tends to get cut off or crammed illegibly at this length.
One line break still counts as a character — splitting the bio into two short lines instead of one uses up part of the 80-character budget on the break itself, which matters more here than it would on a platform with a longer limit to spare.
