The Ultimate Guide to Social Media Character Limits (2026)

You've just crafted the perfect social media post. It has the right hook, engaging value, and a strong call-to-action. You hit publish, and to your horror—the final sentence is cut off with an ellipses (...).

Getting truncated kills your engagement rates. Every major platform has its own strict constraints, and in 2026, those limits are more rigidly enforced than ever before. Knowing the exact character count of your text *before* you post is non-negotiable for digital marketers and creators.

Current Limits by Platform

Twitter (X)

The platform that made character limits famous. Since moving past the original 140 limits, the rules have shifted based on your subscription tier.

• Standard Users: 280 characters
• Premium Users: Up to 10,000 characters
• Profile Bio: 160 characters
• Display Name: 50 characters

LinkedIn

LinkedIn remains the top platform for long-form professional thought leadership. However, the exact point where "See more..." appears is crucial to master.

• Personal Post Limit: 3,000 characters
• Company Page Post Limit: 700 characters
• The "See More" Cutoff: ~140 characters on mobile, ~210 characters on desktop (Make your hook count!).
• Article Limit: 120,000 characters

Instagram

While heavily visual, Instagram captions dictate your algorithm reach through keywords and engaging copy.

• Caption Limit: 2,200 characters
• Hashtag Limit: 30 hashtags per post
• The "More" Cutoff: ~125 characters (First two lines).

SEO Meta Tags (Google)

Technically measured in pixels rather than absolute characters, sticking to these word count rules of thumb will prevent your website from looking messy in search results.

• Title Tag: 50 - 60 characters
• Meta Description: 155 - 160 characters

How to Prevent Truncation

Relying on the platform's native text boxes to warn you is risky. Often, they only tell you you've gone over the *maximum* limit, not the visual cutoff line (like LinkedIn's "See more").
