Does Claude Pro have any usage limits?

Yes. Claude Pro offers at least 5x the usage compared to our free service. The number of messages you can send will vary based on length of message, including the length of files you attach, and length of current conversation. We will provide a warning before you have 7 messages remaining, and your message limit will reset every 5 hours.

Practically what do these limits mean?

If your conversations are relatively short (approximately 200 English sentences, assuming your sentences are around 15-20 words), you can expect to send around 45 messages every 5 hours, often more depending on Claude’s current capacity.

Your limit gets used up faster with longer conversations, notably with large attachments. For example, if you upload a copy of The Great Gatsby, you may only be able to send 15 messages in that conversation within 5 hours, as each time you send a message, Claude “re-reads” the entire conversation, including any large attachments.

Why have these limits?

A model as capable as Claude takes a lot of powerful computers to run, especially when responding to large attachments and long conversations. We set these limits to ensure Claude can be made available to many people to try for free, while allowing power users to integrate Claude into their daily workflows.

Your Claude Pro limits are based on the total length of your conversation, combined with the number of messages you send. Please note that these limits may vary depending on Claude’s current capacity.

In order to get the most value out of Claude Pro:

  • Start a new conversation via the “AI” icon in the top left corner when you want to discuss a new topic. Claude needs to re-read the entire conversation every time you send a message, so starting a new conversation will limit the amount of work Claude needs to do to continue the conversation. Bonus: Claude will also respond faster to shorter conversations.

  • Ask multiple questions at once, especially if you are asking Claude questions about a long document. Because Claude needs to re-read the conversation each time you send a new message, asking questions in individual messages would use up your limit faster than a single message with multiple questions in it.

  • Don’t re-upload files. Claude sees the entire context from your conversation, so you don’t need to upload the same file multiple times (unless you start a new conversation).
