Proximity
Playable Play this law (~3 min)or keep reading below ↓
Elements placed close together are perceived as a group, even without borders, boxes, or shared colour. Spacing alone tells users what belongs with what — which is why a label sits tight to its input and unrelated sections get breathing room. Get proximity wrong and a form feels like confetti; get it right and structure appears for free.
Where it comes from
Proximity is one of the grouping laws from Gestalt psychology, founded by Max Wertheimer in his 1912 paper on apparent motion and developed with Koffka and Köhler through the 1920s. 'Gestalt' means 'unified whole', and the movement's core insight — that the whole is other than the sum of its parts — came from noticing that the mind automatically organises separate marks into groups based on how they're arranged in space. Long before screens, typesetters and mapmakers relied on the same instinct: things set near each other read as belonging together.
Origin: Gestalt psychology grouping experiments, 1910s–1920s
In the wild
- Web forms
A field label hugs its input and sits far from the next field, so you instantly see which label belongs to which box.
- Toolbars
Related actions (bold/italic/underline) are clustered with tight spacing; a gap separates them from a different group of tools.
- Pricing pages
Each plan's features sit close under its price, so the eye reads each column as one self-contained offer.
