To change the size of the logo displayed in your theme, go to “Appearance” -> “Customizer” in your WordPress admin dashboard:
In the theme customizer, go to the “Header” section and you’ll see an “Image Logo Width” field:
Text Logos
Note that the above settings only apply to image logos. If you are using a text logo, the width settings won’t have any effect. If you want to change the size of a text logo, you can add this custom CSS to your site:
#text_logo{
font-size: 33px;
}
Replace the “33px” value with whatever size you prefer.
