How large should touch targets be on mobile website layouts?

Interactive touch targets on mobile websites should maintain a minimum physical dimension of forty-eight by forty-eight display pixels to accommodate human thumb dimensions comfortably. Sufficient visual spacing of at least eight to twelve pixels around each button or hyperlink is equally critical to prevent accidental taps on adjacent elements. Important action buttons should sit comfortably within the natural thumb sweep area, avoiding upper corner placements that force uncomfortable hand readjustment. Standard links embedded within paragraph body text must also feature adequate line-height spacing to ensure clean individual touch selection. Adhering to these touch layout standards drastically reduces user error and drives higher mobile conversion rates.
