Hi there!

As you are using only the logo column, please give it more space/grid in column setting from the Layout builder of your Template Options in case of custom header.

The following document have all the details:

Or If you are using the predefined Header then you can use the following code in your custom CSS:

@media (min-width: 992px){
#sp-logo {
    flex: 0 0 50%;
    max-width: 50%;
}
}

Note: Path towards custom CSS: Extensions>Templates>Styles> Click on your current default template name then choose Template Options. Then find custom CSS within the custom code.

Hope this will solve the issue for you!
