Caption Character Counter

TikTok captions support up to 2,200 characters as of May 2026. Earlier limits were 300 and 4,000; the current cap matches Instagram. Hashtags count toward the limit.

Yes. The count is exactly what TikTok / Instagram / etc. count: every character in the caption field, including spaces, emoji (which often count as 2+), and hashtags.

Mostly no. Most emoji count as 2 or more characters in platform-side counting because they're multi-byte sequences. The counter mirrors this so what you see is what each platform will count.

Each platform decides independently based on its product philosophy. X (Twitter) keeps the historical 280-char cap. Instagram and TikTok converged on 2,200 as long-form caption use grew. LinkedIn allows 3,000 to suit professional storytelling. Bios are always tighter.

Pair this with the video hook generator for opening lines and the YouTube title generator for titles. All three are free, all three work without signup.
