I wanted to resize the chat window to be between 15 and 16 as 15 was too small and 16 was too big but this is not possible due to this error:
![]()
The same thing happens with BubbleChatConfiguration.

You cant use decimals for that property as its an integer type, only allowing whole numbers. Also it’s reading your input as a string and not number, maybe try setting it through the command bar with this: game.TextChatService.ChatWindowConfiguration.TextSize = 15.5
Also, text labels/buttons have integers only. So this probably isn’t a bug but a limitation due to how Roblox’s text system works.
Setting it through the command bar causes it to be automatically rounded instead.
It would still help if roblox improved the system as its not that precise size wise which is a big pain point for me with upgrading to TextChatService.
Hey, just reaching out that this is by design. This is a consistent limitation that is shared with TextLabels and TextButtons and is not unique to TextChatService.
Apologies for any confusion here.
Are there any plans to solve this limitation in the future?
It would allow for finer personalization as i’ve had issues with this limitation on textlabels aswell.
Unfortunately, I am not aware of plans regarding supporting non-whole numbers for TextSizes myself as I’m not on the team that would handle that.
