Fitts's Law: Bigger, Closer Targets Are Faster to Hit
Fitts's Law predicts that the time to hit a target depends on its distance and size. This is why mobile buttons are large and context menus appear at your cursor. The footgun is making everything huge, which sacrifices information density and visual hierarchy.
Fitts's Law is a predictive model for interaction: the time to acquire a target is a function of its distance and size. Closer, larger targets are faster to hit. This guides UI design, from large mobile buttons to context menus appearing at the cursor to minimize travel time. The common footgun is over-indexing on size alone, creating bloated interfaces that sacrifice information density and visual hierarchy for marginally faster clicks.
