TikTok character counter — 4,000 characters, 55 visible in feed
TikTok's caption limit jumped from 2,200 to 4,000 characters — but the first 55 still do all the work in the feed. Paste your caption, see the 4,000 cap and the feed-truncation line at the same time, and fit keywords inside the visible window without blowing the budget.
TikTok's caption limit is one of the most-changed numbers in social media. It was 150 characters at launch, jumped to 300, then 2,200, and in 2023 TikTok raised the cap to 4,000 characters so creators could front-load keywords for TikTok's growing in-app search. But nothing about the feed view changed — the mobile app still collapses captions after roughly 55 characters with a chevron to expand. So the new 4,000 limit is for SEO, not for readers. The counter on this page shows both numbers at once: the hard 4,000 cap and the 55-character visible window. Use the first for your keyword strategy and the second for your hook. Comments stay painfully short at 150 characters, and the bio still caps at 80 — which catches out creators trying to port Instagram bios over verbatim.

What counts as one character on TikTok
Letters are easy. Emoji, URLs, hashtags, and line breaks are where platforms disagree. Here is how TikTok counts them.
| Content | Counts as | Note |
|---|---|---|
| Letter, number, space, punctuation | 1 character | — |
| Emoji | 1 character (grapheme) | TikTok counts emojis by grapheme cluster, same as Instagram. |
| Hashtag (#fyp) | Actual length including # | — |
| Mention (@handle) | Actual length including @ | — |
| URL | Actual length | URLs in captions are not clickable on TikTok, but they still count character-for-character. |
| Line break | 1 character | TikTok renders a single line-break as a space in the feed view; expanded view keeps them. |
| Invisible / zero-width characters | 1 character each | Often used to hack spacing — still chargeable. |
Writing to the TikTok caption budget
TikTok captions now serve two audiences: the viewer watching the feed, and the TikTok search/SEO index. Those two want different things. Here is how to write for both.
Hook in the first 55 characters
The feed shows roughly the first 55 characters before the caption collapses. Everything past that only gets read by viewers who tap expand — a small fraction.
Use the 4,000-character room for keyword context
TikTok's search treats caption text heavily in ranking. A longer, keyword-rich caption ranks for more long-tail search queries, even if most viewers never expand it.
Keep bios under 80 — really under
The 80-character cap includes emoji, line breaks, and any CTA. Most creators waste 20 characters on emoji before even starting the sentence. Paste into the counter, trim, repeat.
3–5 hashtags, not 30
TikTok used to reward lots of hashtags. Current engagement data (SocialInsider 2025, Influencer Marketing Hub) is clear that 3–5 focused tags outperform the keyword-stuffed approach.
Leave room for the on-screen text + overlay
Many viewers read the caption and the on-screen text together. If the on-screen text already carries the full hook, the caption can be shorter — closer to the 120-character sweet spot than the 2,000-char ceiling.
What people use the TikTok counter for
TikTok-specific workflows from the creators and teams using this tool.
Front-loading keywords for TikTok search
TikTok is the second most-used search engine by Gen Z. Captions with the target keyword in the first 50 characters consistently rank better. Use the 55-character truncation marker in the counter as a practical "SEO zone" boundary.
Writing a bio that fits the 80-character cap
The 80-character bio is the tightest on TikTok. It is the space for identity + niche + CTA, and one emoji per element already eats a quarter of it.
Drafting captions without burying the hook
A 2,000-character caption looks great in the editor but terrible in the feed. Use the counter to draft a tight first line, then expand with keywords underneath.
Writing replies that fit the 150-char comment cap
Comments are a main engagement surface on TikTok and capped at 150 characters — tighter than a tweet. Draft longer replies here first if they need to be sharp.
TikTok character counter — FAQ
What is the TikTok caption character limit in 2026?+
4,000 characters. TikTok raised it from 2,200 in 2023 to give creators more room for keywords that feed TikTok's in-app search and SEO. Before 2023 the cap was 2,200, and before that it was 300 and 150 — this number has changed more than any other social media limit.
How much of my TikTok caption is visible in the feed?+
Roughly 55 characters on most mobile devices, sometimes up to ~80 in portrait mode with short text overlays. Anything past the visible window is hidden behind a chevron or "...more" expand. The hook has to live in the visible region or the expansion rate drops to the low single digits.
Do emojis count as 1 or 2 characters on TikTok?+
TikTok counts emojis as graphemes — one displayed emoji, one character. A flag emoji or skin-tone modifier counts as 1, not as the multiple code points it contains internally. This counter uses the same grapheme-based counting, so it matches what TikTok's compose screen will show.
What is the TikTok bio character limit?+
80 characters. Significantly tighter than Instagram's 150 or LinkedIn's 220, and it's one of the most-overlooked limits when people cross-post identity copy. You can add one clickable link in the bio from a business account — the link URL itself is in a separate field and doesn't count against the 80.
How many hashtags can I use on TikTok?+
TikTok does not impose a specific cap on hashtag count — the effective limit is whatever fits in the 4,000-character caption. In practice, engagement data lands on 3–5 focused, relevant tags. More than 5 starts to read as spam and hurts algorithmic reach.
Does a TikTok comment have its own character limit?+
Yes — 150 characters. Comments are capped at exactly the old pre-2023 caption length. Long replies get rejected unless split into multiple comments. Draft in the counter if you're writing a longer creator-to-creator reply.
