Tap Target Size

Screen controls should be large enough for users to tap easily and take into account that every user’s hands are sized differently. Controls that are too small means users will need to tap multiple times, a frustrating experience. But you don’t want controls so large that users can accidentally tap one when they meant to tap another.

We recommend a minimum tap target size of 44 pixels wide by 44 pixels high. For more information about custom icons, see Custom Icon Guidelines and Best Practices.
