X (Twitter) Spaces Guide: Title and Description Character Limits
X Spaces is the platform's live audio feature, allowing users to host real-time conversations with their audience. While the audio content has no character limit, the metadata that promotes your Space — title, description, and scheduling details — must work within specific constraints.
Spaces Character Limits
| Element | Character Limit | Notes |
|---|---|---|
| Space title | 100 | Displayed in the Spaces card |
| Scheduled Space description | 280 | Same as a standard post |
| Promotion tweet | 280 | Standard post limit applies |
Writing Effective Space Titles
Your Space title is the primary driver of attendance. In 100 characters, you must communicate the topic, value proposition, and urgency:
- Be specific: "How to grow on X in 2026" outperforms "Social media tips"
- Include keywords: Users search for Spaces by topic
- Create urgency: "LIVE NOW:" or "Ask Me Anything:" signals immediacy
- Name guests: If you have notable speakers, include their names
Audio Content Best Practices
- Open with a clear agenda in the first 2 minutes
- Keep individual speaking turns under 3 minutes
- Invite audience questions every 10–15 minutes
- Summarize key points before closing
- Record the Space for later sharing (available to hosts)
Promotion Strategies
Schedule your Space at least 24 hours in advance and promote it with multiple tweets. Include the topic, time (with timezone), and a reason to attend. Pin the promotion tweet to your profile for maximum visibility.
Audience Engagement
- Use the hand-raise feature to manage speaker queue
- React with emoji to acknowledge listeners
- Share relevant links in the Space's pinned tweet
- Follow up with a thread summarizing key takeaways
Conclusion
X Spaces combines the intimacy of audio with the reach of social media. Craft your title and description carefully within the character limits to maximize attendance. Use Character Counter to optimize your Space titles and promotion tweets.
