Mobile menu switch at different horizontal pixel size

Hi, I added some more items in my menu:

Now the switch from standard to mobile menu is too late insofar as some menu items overlap into the logo before it switches to the mobile version. Where can I adjust the horizontal pixel size at which it switches to mobile?

Hi,
Please navigate to your MusicState -> Template Options -> Layout tab. Here you can change screen size form mobile or tablet view.

Thanks, that did it.
