The 2026 Social Media Character Limit Reference Guide
Maintaining proper character count across multiple social networks is essential for organic reach and engagement. When your post is truncated prematurely, your call to action and value proposition get buried behind “see more” buttons.
X (Twitter) Character Limits
Standard accounts are limited to 280 characters. If you are drafting a thread, each individual tweet must adhere to this 280-character limit. Spaces, emojis, and punctuation all count toward your total. URLs typically consume 23 characters regardless of their raw length due to Twitter's t.co wrapper.
LinkedIn Post Limits & Truncation
LinkedIn provides a generous ceiling of 3,000 characters for standard feed updates. However, the first 140 to 210 characters are what users see on mobile and desktop before the fold. Your first two lines must generate enough intrigue or value for the reader to click “see more.”
Instagram Caption Length
Instagram captions permit up to 2,200 characters and up to 30 hashtags. Truncation occurs after approximately 125 characters. For optimal engagement, place your primary hook in the opening sentence and leave hashtag blocks toward the footer.
TikTok Video Descriptions
TikTok descriptions allow up to 2,200 characters. TikTok functions increasingly as a visual search engine, making keyword-rich captions a major factor in driving organic video discovery.
