The Roblox chat character limit has historically been around 50 characters visible per chat line , based on player reports and discussion threads. That said, the exact limit can vary by chat system, game, or UI update, so what you see in practice may differ.

Quick Scoop

If you mean the text length allowed in chat , a good rule of thumb is to keep messages to about 50 characters if you want them to display cleanly in the older Roblox chat interface.

If you mean the height/size of the Roblox character avatar , that is a different question and depends on the avatar body parts, scaling, and accessories rather than a fixed chat-related limit.
