What is the best font size for mobile apps?
Mobile apps for Android use a minimum font size of 12 pixels, while iOS uses a minimum font size of 11 points. These app design standards ensure readability and are the most recommended font size for the main body text on mobile apps.
How many fonts should I use in my app?
Tip #3 Never Overdo Mixing of Fonts on Any Particular Project. Too many fonts on any given app page spell clutter, discouraging users from reading with intent. Keep the app design limited to a certain number of fonts that resonate with the brand mood. Ideally, avoid using more than two typefaces on mobile.
