Spacing Systems

Base-4 Scale (Recommended)

4  8  12  16  20  24  32  40  48  64  80  96  128

Why 4: divisible by 2 (half-pixel precision), works with common grid gutters.

Base-8 Scale (Alternative)

8  16  24  32  40  48  64  80  96  128

Coarser, fewer decisions, works well for spacious designs.
