Why does the touch target matter?
Even if the icon artwork itself is small, the actual tappable area β padding included β needs to be large enough to hit reliably. Apple's Human Interface Guidelines recommend a minimum of 44Γ44pt, Google's Material Design recommends 48Γ48dp, and the web accessibility standard WCAG 2.5.5 sets a minimum of 24Γ24px. Ignoring these guidelines leads to frequent mis-taps, especially for users with larger fingers or in situations that make precise tapping harder, like walking or driving.
Pick your platform, then enter the current touch target size and the gap between adjacent icons, and this tool instantly tells you whether it meets that platform's standard. Keeping at least 8px of spacing between neighboring icons also helps reduce accidental taps.
