Roblox chat messages are generally capped at 200 characters. A Roblox DevForum post notes that the chat has a 200-character limit, and another discussion about the newer chat system also refers to messages over 200 characters triggering a “message too long” condition.

Quick Scoop

  • Standard Roblox chat limit: 200 characters.
  • Why people hit it: long replies, pasted text, and emoji or multibyte characters can make messages reach the limit faster in some chat setups.
  • Different areas may have different rules: forum posts and text boxes can have separate character limits from in-game chat.

Practical note

If you’re trying to send a longer message, the usual workaround is to split it into multiple chat messages. In some Roblox chat systems, non-ASCII characters can also behave a little differently when the limit is checked.

TL;DR

Roblox chat is usually limited to 200 characters per message.
