How does Roblox Have Nice Sized Text In their chat UI while Text Scaled Boxes cant?

When Typing In ROBLOX's Chat UI , If you were to type a Long Sentence , the Size of each letter stays the same , But If you were trying to mimic that with a text box and turned on Text Scaled , then the more text you would type , the smaller the letters would get. Some Times the Text Wont even indent

How can I Make it so when Something Is typed in a text box , the letters are evenly the same size Just Like ROBLOX's Chat GUI ?

You can wrap and scale the text for the textbox. At least that's the answer I'm pretty sure you're asking for.

Because TextScaled attempts to shrink the text to fit within the X bounds of the text container until it gets too small, then it will wrap around. Roblox doesn't use text scaling, they used a fixed font size and textwrapping.
