Level: Basic
A button or link that's easy to click with a precise mouse cursor can be genuinely difficult to tap accurately with an imprecise finger on a touchscreen.
Size Targets Generously for Touch Input
A commonly cited minimum touch target size helps ensure buttons and links are comfortably tappable without requiring pixel-precise accuracy.
Add Sufficient Space Between Adjacent Targets
Tap targets placed too close together increase the chance of accidentally tapping the wrong one, even if each individual target is sized adequately.
Consider Thumb Reach on Larger Phones
On bigger devices, targets placed at the very top of the screen can be genuinely difficult to reach one-handed, which is worth factoring into placement decisions.
Next step: Use the Webpage Screen Resolution Simulator to test your current tap targets across different device sizes to confirm they're genuinely comfortable to tap.
