How to increase the size of the logo?

With the default header the maximum recommended logo height is 60px. The width doesn’t really matter – the logo will push menu to the right no matter how wide it is.

If you need more than 60px insert the following css statements in Customize > General Settings Custom CSS field:

.logo a img {
    height: 80px;
    padding-top: 15px;
.mainNav {
 padding-top: 20px;

Please adjust the numbers according to your needs. The first number (80px) represents the height of the logo, the second (15px) and the third (20px) represent the top margin between the viewport's top and the content.
