Quickest way I found to increase the font size of the menu of the Object Explorer on Microsft SQL Server Management Studio:
- Click on TOOLS, then go to OPTIONS at the bottom.
- The key is to change the font type from Environment>Fonts and Colors, as if you don`t, it is set to default and it will not let you change the Size.
- Increase the font size, then click ok, no need to restart the app.

4. Voila! Font size of the Object Explorer`s menu increased.
