Character Counter
Check character counts against platform limits for SEO, SMS, social, and ads
Count characters for any platform with specific limits: Twitter/X, LinkedIn, Instagram, meta titles, meta descriptions, SMS, and email subject lines. See when you're over the limit and get suggestions to cut or expand.
Character Limits by Platform
| Platform / Field | Limit | Notes |
|---|---|---|
| Twitter/X post | 280 chars | Links count as 23 chars |
| LinkedIn post | 3,000 chars | First 200 shown without "see more" |
| Instagram caption | 2,200 chars | First 125 shown in feed |
| Google title tag | ~60 chars | Google truncates at ~580px |
| Google meta description | ~160 chars | Truncated at ~920px |
| SMS message | 160 chars | Multi-part SMS charges extra |
| Email subject line | 40–60 chars | >60 gets cut on mobile |
| YouTube title | 100 chars | First 70 shown in search |
| YouTube description | 5,000 chars | First 150 in search snippets |
Why Character Counting Matters for SEO
Google doesn't use a fixed character limit — it measures pixel width. But 60 characters is a reliable guideline for titles. Titles cut in search results look unprofessional and lose clicks.
For meta descriptions, being under the limit isn't enough — you need a compelling CTA within 160 characters. The SEO Meta Tag Analyzer checks your actual title and description against these limits directly on a live URL.
Counting for Automation Outputs
If you're using AI to generate content in automation workflows (email subject lines, social posts, SMS messages), always add a character-count validation step. This tool lets you manually check; in production, enforce limits in your code with a len() check or a truncation function. If you're counting words rather than characters, the Word Counter covers that side, including reading time estimates.
