Character limits by platform

Current character limits across major social platforms (as of 2026). Going over a limit either blocks publishing or truncates your post — check with the counter above before you hit publish.

Platform	Field	Limit	Notes
Instagram	Caption	2,200 chars	Feed truncates after ~125 chars behind “more” — put the hook first
Instagram	Hashtags	30 max	Posts with more than 30 hashtags are rejected
Instagram	Bio	150 chars	Including links and emoji
Threads	Post	500 chars	Split longer pieces into a connected thread
X (Twitter)	Post	280 chars	CJK characters count as 2 — Korean-only text maxes out around 140
YouTube	Title	100 chars	Search results often cut titles around 70 characters
YouTube	Description	5,000 chars	Only the first 2–3 lines show before the fold — key links go on top
LinkedIn	Post	3,000 chars	Feed collapses after the first 2–3 lines behind “see more”

Tips for working within the limits

Win the first 125 characters

Instagram folds captions behind “more” after roughly 125 characters. Put your core message and hook inside those first 125 characters, and push details and hashtags below the fold.

Treat X as 140 characters for CJK text

X's 280-character limit counts Korean, Chinese, and Japanese characters as 2 each. If you write mostly in a CJK language, plan for about 140 characters of real space.

Rewrite per platform, don't just crop

The same idea works better short and conversational on Threads (500) and longer and structured on LinkedIn (3,000). Keep one source text and reshape it for each platform's grammar.

Line breaks and spaces count too

The blank lines you add for readability count toward the limit on most platforms. When you're close to a limit, watch the with-spaces number, not the without-spaces one.

Frequently asked questions

Do spaces count as characters?: Yes. Instagram, Threads, X, and most other platforms count spaces and line breaks toward the limit. This tool shows both with-spaces and without-spaces counts, and the platform checks use the with-spaces count — the same way the platforms do.
Where does Instagram's “more” cut the caption?: In the feed, Instagram collapses captions after roughly 125 characters (including line breaks). The exact point varies slightly by device and language, so keep your core message within the first 125 characters. The full caption limit is 2,200 characters.
Why is X effectively 140 characters for Korean?: X weights characters differently: Latin letters, digits, and basic punctuation count as 1, while CJK characters and emoji count as 2. The total weight must stay under 280, so Korean-heavy text effectively maxes out around 140 characters. The X row in this tool applies the same weighting. One difference: X counts every link as 23 characters regardless of its real length, while this tool counts links character by character — so text with links may read slightly longer here.
How are emoji counted?: This tool counts each emoji as one character, the way a person sees it (grapheme-based, per the Unicode standard). Platforms may differ — X counts emoji as 2, for example. The byte count shows how much space the text takes in UTF-8 if you need a storage-based figure.
