Our Typography add-on (linked above - thanks Silvio!) allows you to do this through the Customizer.

You can also use CSS:

.main-navigation li a {
      font-size: 15px;
}

... But making changes to the style.css only child template, the changes remain intact after an update. ;-)

Thank you so much, Tom. That worked perfectly. :)

No problem :)
