TikTok Character Counter
TikTok captions can be up to 2,200 characters, but the platform primarily uses caption text as a topic and keyword signal for its recommendation algorithm. Captions of 100–300 characters perform best — long enough to include relevant keywords and context, short enough that viewers actually read them before the video starts.

Frequently Asked Questions
Do TikTok captions affect how many views you get?
Yes — TikTok's algorithm uses caption text as one of many signals to determine which audience should see your content. Keyword-rich captions help the algorithm categorise your video correctly and recommend it to users interested in that topic. A well-written 100–300 character caption can meaningfully improve discoverability.
Should I use hashtags in TikTok captions?
Hashtags on TikTok serve both discovery and algorithmic categorisation purposes. Use 3–5 relevant hashtags — a mix of niche-specific and broader ones. Hashtag stuffing (20+ hashtags) is generally considered ineffective and can look spammy. Include them at the end of the caption.
How long can a TikTok caption be?
TikTok allows up to 2,200 characters for video captions. However, viewers are primarily watching the video, so captions longer than 300 characters are rarely read in full. Prioritise keyword value and clarity within the first 150 characters.
