Chunking

Turn many details into a few meaningful groups.

01 / UNDERSTAND

The idea

Information is easier to work with when related items form recognisable units. A group needs a useful meaning, such as billing details, an upcoming lesson or a project’s channels. Simply drawing boxes around arbitrary items does not create a helpful chunk.

Start with the distinctions people already make while doing the task. Give each group a clear label and arrange its contents in a predictable order. This lets a reader scan for a category before interpreting every item. Keep essential comparisons together, and check whether the grouping still makes sense on a narrow screen. Chunking is a structure for understanding; it is not a reason to hide needed context or force every group to contain a fixed number of items.

02 / RECOGNISE

See it in real products.

Examples of how the principle can appear in an interface.

DuolingoEXAMPLE 01

Make a course understandable one section at a time

Duolingo’s course menu presents a sequence of named sections with their own progress. That gives a learner a higher-level unit for understanding the course before inspecting individual lessons. The grouping illustrates chunking: a section carries meaning that the learner would otherwise have to reconstruct from many separate exercise nodes.

SlackEXAMPLE 02

Organise conversations into a recognisable workspace structure

Slack’s published Home walkthrough groups channels and direct messages under recognisable headings. These categories let people choose a kind of conversation before reading every item. Test whether the grouping matches actual work rather than relying on the hierarchy’s appearance.

03 / CONNECT

Why it matters.

Meaningful groups can support scanning and comprehension. Test whether people predict where information belongs and find it without opening every group.

Possible influences to investigate, rather than guaranteed outcomes for every product.
