Hello,

The size from the “width and height attributes” option comes from the WordPress media, hence if you want to appear the full size of the logo you should disable this option.

As for the problem with the logo size when you surf on pages, it can be influenced by third-party plugin options (e.g “lazyload”).

Kind Regards
