Unifying spacing and sizing across layouts

Spacing and sizing work best when they support each other across an entire layout. Spacing sets the rhythm between elements, while sizing shapes the elements themselves. When both follow the same base unit, the layout becomes easier to scan because every part of the page feels connected. Lists, cards, sidebars, and sections align more naturally, and users can follow the flow of content without effort. Grids become clearer as well because gutters, columns, and component sizes all follow the same structure.

These shared rules help layouts stay consistent across screen sizes. Column grids with defined gutters create predictable horizontal spacing, while the spacing scale shapes vertical rhythm. When elements like cards or images use sizing values that align with the grid, they snap neatly into place. This keeps layouts balanced whether they use two columns, three columns, or a denser arrangement. Even when layouts shift between adaptive, responsive, or strict patterns, unified spacing and sizing make the transitions feel smoother.

Applying both systems together also reduces the number of one-off decisions designers need to make.
