Hi there!

Thanks for contacting us! You can use the following code into your custom CSS:

.offcanvas-inner .sp-module.offcanvas-logo {
    width: 250px!important;
}

You can change the value if you want to fit your own need.

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.
