Spacing in Design System is an essential element that plays a key role in creating a cohesive and user-friendly interface. By establishing consistent Spacing values for margins, paddings, and alignments, teams can achieve visual harmony and enhance the overall user experience. This standardized approach ensures that components in a component library or UI library align and relate to each other in a predictable manner, reducing cognitive load for users.

Moreover, Spacing provides breathing room, allowing content to be easily scannable. A well-defined Spacing system not only improves the aesthetics of a design but also contributes to the usability and accessibility of the interface, making it an indispensable aspect of any comprehensive Design System.
