Gestalt principles of perceptual organization

Rules by which perception groups what we see: things that are close, look alike, follow the same line or share an outline are seen as a whole.

What problem it addresses

Explains why a screen or a poster is understood at a glance or looks messy, even with the same elements.

The same nine fields of a form, with different spacing.

All at the same distance

Nine fields spread out evenly. A long list.

Grouped by proximity

The same fields in three groups, with more space between groups. Three blocks that read on their own.

No need to add headings or lines: distance is enough for the eye to form the groups.

Use it like this
Group with space before adding lines, boxes or headings.
Avoid
Spacing everything evenly, related or not, or placing unrelated things close together.
Don’t fall for it
If everything looks alike, nothing stands out: save difference for what needs to be distinguished.

A century

Later research on grouping and figure-ground relationships confirms and extends what Wertheimer proposed (Wagemans et al., 2012).

Solid evidence. The principles describe tendencies, not exact laws: when several compete with each other, the outcome depends on the case.

Described how we group dots and lines: by proximity, similarity, continuity or closure.

Reviewed a century of research, including principles described after Wertheimer, such as common region.
