How to increase the log width

In custom CSS, please add:

#sp-header .logo {margin-right: 0;}  
body.predefined-header1 #sp-header {padding: 30px 20px 100px 25px;}  

You can also increase the sidebar width more and/or reduce the value of the left and right padding. It allows you to increase the space reserved for menu items and the logo too.
