The header, being the central navigation element of a product, must be instantly and effortlessly scannable by users. They shouldn't struggle to understand what's included in the header. This is where the significance of header spacing comes into play.

Keep text labels short and to the point, allowing users to quickly grasp their meaning. Ample space should surround the logo, buttons, and other interactive elements. This spacing prevents the elements from appearing cluttered and helps users easily differentiate and select the options they need instead of accidentally clicking something else.
