Chunking
Grouping items into meaningful units makes them easier to scan, understand and remember.
Why it matters
People handle several small groups much more easily than one long string.
How to use it
- Format long numbers in groups.
- Split long forms into sections.
- Use headings and short paragraphs.
Example
A card number shown as 4242 4242 4242 4242 is easier to check than 4242424242424242.
