Massimo,
Assuming that you’re using the Atlas Top Bar template(s), you can control the sub-menu font size in the custom-variables.scss file. Look for a variable named $navtopbar-sub-font-size.
See if that does it for you.

Hi Scot.
Thank you for your answer.
In custom-variable.scss I found this definitions:
$font-size-small: 12px;
$navigation-sub-font-size: $font-size-small;
Changing it doesn’t fix the issue.
For some reason, the styling in the Atlas_Core module for this feature has changed.
To fix it change font-size for .navbar-brand .a in themesource\atlas_core\web\layouts\_layout-atlas.scss
or overwrite that feature in your own styling definitions.
