Hi ​@Shuli 

thanks for your question!

When you’re working with the Org Chart (Diagram) feature, the text size inside the boxes is currently auto-adjusted to fit the shape and can’t be manually resized with the standard text editing tools. That’s why copying larger text doesn’t change the size either.

Workarounds you can try:

• If you need larger text, you can resize the box itself — the font will scale proportionally as the shape gets bigger.

• For more flexibility, you can add a separate text box on top of (or next to) the org chart shape and style it however you like (font size, bold, color, etc.).

• If the org chart requires more advanced formatting, some teams choose to build the structure with shapes + text manually, instead of using the auto-layout org chart tool.

Hope this helps!

HI ​@Shuli 

​@Eca had a good answer if you are working with org charts - and you did use the word “chart” 

But . . . 

In case you are working with shapes, then I do have a tip/trick for you. If you just try to resize a single shape, the text stays the same size:

But, if you select several shapes at the same time and re-size them, the text will change size!

I don’t think this is an accident but it is most like an INCREDIBLE feature from some anonymous Miro software developer who really thought through this at a deep level and deserves a huge salary increase but probably didn’t get it.   Because . . . normally if you resize a single shape, it is in the context of other shapes - so you want the text size to stay the same. But . . . if you resize several shapes, most probably your intention is to make everything bigger or smaller. 

IMHO - BRILLIANT!

Hope this helps!
