Small buttons lose mobile taps

A mouse pointer is 1 pixel. A fingertip covers roughly 44 pixels. Every button designed for a cursor that gets tapped by a finger has a miss rate.

Apple's Human Interface Guidelines recommend a minimum touch target of 44x44 points. Google's Material Design says 48x48dp. Both arrived at similar numbers because human fingers are roughly the same size regardless of operating system.

Buttons below these minimums don't just feel small. They produce measurable tap errors. Users hit the wrong thing, nothing happens, or they accidentally trigger adjacent elements. Each mis-tap is a moment of frustration that erodes the conversion flow.

The fix is simple: make every interactive element at least 44px tall with 8px of space between adjacent targets. This includes form inputs, links in navigation, and dropdown triggers. If the visual button looks right but the clickable area is smaller than 44px, add transparent padding to expand the hit zone.
