How do you design for touch targets on mobile devices?

• A. Minimum target size 44x44 dp; adequate spacing; accessible hit areas.
• B. Targets should be as small as possible.
• C. Touch targets are irrelevant on small devices.
• D. Rely on hover effects for touch.

Answer: (A)

Designing for touch targets on mobile means making interactive elements easy to tap with a finger. The recommended minimum is a size around 44x44 dp (density-independent pixels) so the tap area is large enough across different screen densities and device sizes. Using dp ensures consistency, not pixels that vary with screen resolution. Adequate spacing between targets prevents accidental taps when your finger slips, and accessible hit areas support users with different finger sizes or motor difficulties by providing clear, generous tap zones and visible feedback when pressed.

On touch devices, hover isn’t applicable because there’s no cursor to hover over elements, so relying on hover effects for interaction is ineffective. Larger, clearly tappable targets with responsive visual states provide a reliable, finger-friendly user experience. Smaller targets or treating touch targets as irrelevant would degrade usability.
