Social & SEO
The Social Media Character & Limit Counter evaluates caption copy against hard limits, truncated feed cutoffs, and hashtag ceilings across Twitter/X, Threads, Instagram, TikTok, LinkedIn, YouTube, and Pinterest.

📋How to Use This Tool

  1. Input Post Text: Type or paste your post copy into the input area. Characters, words, hashtags, and reading time update in real time.
  2. Inspect Platform Limit Cards: Check visual progress bars and status badges for Twitter/X (280), Threads (500), Instagram (2,200), LinkedIn (3,000), and YouTube.
  3. Review Mobile Truncation Cutoffs: Ensure critical hooks appear before feed cutoff thresholds (e.g. YouTube titles under 60 chars, LinkedIn preview under 210 chars).
  4. Copy Clean Copy: Copy your verified post directly to your social management tool, scheduling dashboard, or mobile clipboard.

⚙️Technical & Educational Details

Calculates Unicode string length using standard UTF-16 code units and grapheme cluster boundaries, accounting for multi-byte emojis, t.co URL shortening constants (23 characters on X), and platform-specific truncation thresholds.

• Twitter / X: 280 characters limit (free tier), URLs count as 23 characters
• Instagram: 2,200 characters limit, truncates at 125 characters, 30 hashtags maximum
• LinkedIn & TikTok: 3,000 chars limit (LinkedIn cutoff ~140-210 chars), 2,200 chars limit (TikTok)

  • Optimizing YouTube video titles to prevent truncation on mobile search result lists.
  • Crafting compelling LinkedIn hook paragraphs that convince readers to click '...see more'.
