Question 1

How many characters can a tweet be on Twitter/X?

Accepted Answer

Standard Twitter/X accounts can post tweets up to 280 characters. However: Twitter Premium (Blue / X Premium) subscribers can post long-form posts up to 25,000 characters; URLs are always counted as 23 characters regardless of their actual length (Twitter wraps them in t.co shortened links); images, videos and GIFs do not count against the character limit; @mentions and hashtags count normally. The live character counter shows how many characters remain against the 280 limit.

Question 2

What is the LinkedIn post character limit?

Accepted Answer

LinkedIn post character limits by type: Regular text post — 3,000 characters; Article body — 125,000 characters; Article headline — 200 characters; Comment — 1,250 characters; Connection request message — 300 characters; InMail subject — 200 characters; InMail body — 2,000 characters; LinkedIn Page post — 700 characters (recommended), 3,000 characters (maximum); Profile summary (About) — 2,600 characters. Posts longer than ~210 characters are truncated in the feed with a 'see more' link — front-load your key message.

Question 3

What is the Instagram caption character limit?

Accepted Answer

Instagram caption limit is 2,200 characters. However: captions are truncated in the feed after 125 characters (mobile) or 3 lines — the rest is hidden behind a 'more' link; hashtags count toward the 2,200-character limit; you can add up to 30 hashtags per post; Instagram Stories captions are limited to 250 characters; Instagram bio is limited to 150 characters; DM messages have no strict public limit but very long messages are split. Best practice: put your hook in the first 125 characters.

Question 4

Does punctuation and spacing count in character counts?

Accepted Answer

Yes — every character counts including spaces, punctuation, line breaks (newlines) and emojis. Important notes for emojis: most emoji are 2 characters in Unicode (they use 'surrogate pairs'), so a single emoji counts as 2 characters in JavaScript-based character counters. However, Twitter counts most emoji as 2 characters regardless of Unicode encoding. Some complex emoji (flags, family emoji with modifiers) can be 4–8+ characters. The counter shows the exact character count as each platform would measure it.
