Official Twitter (X) Bio Character Limit Rules
Your ๐ bio is the first piece of copy that potential followers read when deciding whether to follow your account. Understanding how character limits work on profile pages helps you avoid awkward truncations:
- Raw Length Metric: Unlike the 280-character post feed where URLs are compressed to 23 characters, links typed directly into the bio text field count character-by-character.
- Emoji Weighting: All emojis consume 2 characters toward your 160-unit allowance.
- Line Breaks: Hitting the Enter key to create vertical spacing consumes 1 character (for the newline
\ntoken) per line break.
The 4-Part High-Converting ๐ Bio Formula
Fitting your entire value proposition into 160 characters requires crisp copywriting. Top creators and brands use this structured formula:
1. The Authority Hook
State who you are or your primary role in 3โ6 words (e.g., "Founder @Acme | SaaS Growth Engineer").
2. The Audience Promise
Explain what followers learn from your feed (e.g., "Sharing daily systems for building 7-figure digital products.").
3. Concrete Social Proof
Add a metric or credential (e.g., "Ex-Google • Built 3 apps to $10M ARR").
4. Direct Call-to-Action
Direct attention to your pinned post or website link below (e.g., "๐ Read my free guide below").
