The example works for me and font sizes are as expected for all symbols, but here are some ideas.

First, when using PPT or Excel, make sure that there are no other ODS destinations open. The styles/options set by one ODS destination may influence what you see in others. In EG you might have SAS Report or HTML on by default, and in SAS Studio you have HTML5 by default. Here's an article about how to control this in EG.

Next, when specifying a font in code for Windows, the font name needs to be exact. Check the font names in your Windows Font directory.
