TikTok allows longer captions, but the first line is what people see. Highlight is the first ~80 characters; red is past 150. Nothing leaves this page.
How long can a TikTok caption be?
Captions allow up to 2,200 characters now, but the first line still does the work. This checker treats 150 characters as a practical on-screen cap and ~80 as the hook people see before ‘more’.
