01 / THE IDEA
What does it mean?
Fitts's Law relates target selection time to the target's size and distance. Bigger, well-placed targets are often easier to use.
02 / IN PRACTICE
Make it concrete.
Illustrative example: A primary mobile action gets a generous touch target instead of a tiny text link.
03 / WHAT TO WATCH FOR
A common mistake.
Making a destructive action oversized just because it is frequently tapped.
04 / WHEN IT HELPS
When should you use it?
When people miss controls, especially on mobile or with motor limitations.
