Setting the logo height is a fairly straightforward process with all our themes. Depending on the theme you are using, there are a few ways you could go about this.
Some of our themes will have the option to set the Logo Height under Theme Options > Logo:
Other themes might have the Logo Area Height setting under Theme Options > Header:
Make your logo retina-ready!
When viewed on high-density Retina displays, image dimensions are being divided by two. Simply upload the logo in double the size from how it will appear on your live website. E.g. in case the logo size on your website would be 100x100px, just upload the logo with the size of 200x200px. This will effectively make your logo super sharp and it will look completely amazing on devices with retina-ready screens!
In case your theme does not have the Logo Height setting, the maximum logo height will usually be determined by the header height option in Theme Options > Header.
To illustrate this further - if your header height is set to 100px, your logo holder will have a height of 90px, and that means that the logo image that you need to upload should have a height of 180px.
