Pointing at a small, distant target generally takes more time and precision than selecting a larger, nearby one. This relationship concerns movement to the target, including the size of its usable hit area. A visually large icon can still be difficult if only a tiny part is clickable.
Consider the whole interaction: where the pointer or finger starts, the target’s dimensions, nearby competing controls and the cost of a mistaken selection. Frequent actions should be reachable without demanding precise movement. Preserve comfortable separation around destructive actions rather than merely enlarging everything. Test with the actual device and people using different input methods. A convenient mouse target may still be difficult for someone using touch or experiencing reduced dexterity.

Examples of how the principle can appear in an interface.
Allow important controls to occupy a larger target
Apple’s Control Center lets people resize supported controls. The editing interface shows handles on the controls, including large slider-shaped areas. It is a concrete place to examine whether a frequently used action offers enough selection area, while checking the remaining spacing and the person’s preferred control layout.
Slack’s create control opens a menu for common creation actions from a predictable navigation location. Examine the target’s usable size, travel distance and neighbouring controls. Its placement illustrates a selection question; it does not establish a measured improvement in pointing performance.
