Icons for Mobile Apps
Mobile interfaces have strict constraints that desktop UIs do not. Touch targets must be at least 44x44px for reliable tapping. Icons must be readable on varying screen qualities from budget Android devices to Retina displays. Navigation patterns like tab bars and hamburger menus rely heavily on universally recognized icons.
WHY THIS MATTERS
//On mobile, users tap icons with their thumb while moving. An icon that is too small, too ambiguous, or too similar to an adjacent icon causes tapping errors. These errors create frustration that leads to app abandonment.
RECOMMENDED FOR ICONS FOR MOBILE APPS
DESIGN TIPS
Minimum touch target is 44x44px — the visible icon can be smaller but the tappable area must not be
Use 24px to 28px visible icon sizes for tab bars and action buttons
Filled icons work better than outline icons in mobile tab bars — they are more visible at a glance
Avoid icons that are too similar — home, house, and building icons can be confused on small screens
Always pair tab bar icons with text labels
MUST-HAVE ICONS FOR THIS USE CASE
COMMON MISTAKES TO AVOID
Touch targets smaller than 44x44px
Icon-only tab bars without text labels
Using the same icon for multiple different actions
Outline icons that are too thin to read on low-quality screens
