change header font size

@vmdials Do you mean the menu items at the very top?

yes

Try this in Appearance > Customize > Additional CSS

.navbar-custom .navbar-nav > li > a {
    font-size: 14px;
}

Maybe I wasn’t clear. I was referring to the top left and top right – social menus.

@vmdials Try `.top-menu>li>a {
font-size: 16px;
}`

Thank you. It increases font size, but text is cut off on the right side.

Can you please show me a screenshot?

@vmdials I see what you mean – do you want to show social media links on the right hand side? if so, can you please go ahead and set up the icons and then we can tweak the size.
