Claude's Max plan has several types of usage limits designed to provide substantially higher capacity than the Pro plan while maintaining fair access for all users.
The Max plan offers two usage tiers with different message allowances[1][2]:
- Expanded Usage (5x Pro): At least 225 messages every 5 hours
- Maximum Flexibility (20x Pro): At least 900 messages every 5 hours
For context, Pro users typically send around 45 messages every 5 hours, making the Max plan a significant upgrade for heavy users[4].
