Hello paulrosso,
Thank you so much for using our theme SuperNews. Based on the design purpose, we developed that size of the logo. If you want to increase or decrease the logo size, you can skip cropping the logo size or can edit the theme code. Find the custom-logo inside the acmethemes/core.php and change the height and width of the logo as your need.
Hope, this will help to customize the theme.
Note: Child theme is recommended to customize the theme.
Regards
Acme Supports
