Reply To: Header size and Logo size on Header

It looks like you’ve already added some space in your Nav. If you want to add more, check out line 1282 in your CSS where you’ve added this –

.genesis-nav-menu a {
	color: #fff;
	display: block;
	font-size: 15px;
	font-weight: 300;
	letter-spacing: 2px;
	padding: 75px 17px;
	padding-top: 113px;
	padding-bottom: 23px;
	padding-left: 11px;
	text-transform: uppercase;
}

You can adjust your padding here to increase/decrease space. Just make sure not to forget what I mentioned earlier about the 1200px space. If your Nav/Menu is too wide with your logo, then it won’t fit inside the header area. So make sure your padding isn’t too much to cause the Nav to get pushed down.
