Social Media Character Limits: The Complete 2026 Cheat Sheet

Every platform cuts you off at a different length, and most don't warn you until your carefully written post gets truncated with an ugly "…". Here's the complete reference — bookmark it, or just paste your draft into the free Word Counter, which tracks the important limits live as you type.

The limits that matter

Platform Limit
X (Twitter) post 280 characters (25,000 for Premium)
X display name 50 characters
Instagram caption 2,200 characters (truncates after ~125 in feed)
Instagram bio 150 characters
LinkedIn post 3,000 characters (truncates after ~210 in feed)
LinkedIn headline 220 characters
Facebook post 63,206 characters (truncates after ~477)
TikTok caption 2,200 characters
YouTube title 100 characters (~70 visible in search)
YouTube description 5,000 characters
SMS 160 characters (concatenated after that)
Google title tag ~60 characters before truncation
Google meta description ~160 characters before truncation

The "visible before truncation" trap

The hard limit isn't the number that matters most — it's the fold. Instagram shows roughly the first 125 caption characters before "more"; LinkedIn about 210; Facebook about 477. Whatever your hook is, it has to land before that point or most people never see it.

Practical rule: write your first sentence as if it's the whole post. Front-load the payoff, not the wind-up.

Why "characters" isn't always what you think

  • Spaces count on every platform above. "Characters excluding spaces" is a different number used mainly in translation billing and some academic submissions — a good counter shows both.
  • URLs on X always count as 23 characters, no matter how long they are, thanks to the t.co wrapper.
  • Emoji often count as 2+ characters because they're multi-byte — an emoji-heavy post hits limits faster than it looks.
  • SMS drops to 70 characters per segment if your message contains any character outside the basic GSM alphabet (including some smart quotes and emoji) — that's why one emoji can turn one text into three.

Word counts, for the longer stuff

While we're at it, the targets people ask about most:

  • Blog post for SEO: no magic number, but competitive queries are usually won by 1,000–2,500 word pieces that actually answer the question.
  • Meta description: ~25 words (160 characters).
  • 5-minute speech: ~650 words at a comfortable 130 words/minute speaking pace.
  • 1-minute video script: ~130–150 words.

The Word Counter shows reading time (200 wpm) and speaking time (130 wpm) alongside the counts, so you can size a script or article without doing the math.

Count as you write, not after

The workflow that saves the most rewriting: draft directly in the Word Counter with the platform limits panel open. Every limit updates live, over-limit platforms turn red, and — because it runs entirely in your browser — your unpublished drafts never leave your device.
