Guidelines for touch targets
In this article
All interactive UI elements in your Windows application must be large enough for users to accurately access and use, regardless of device type or input method.
Supporting touch input (and the relatively imprecise nature of the touch contact area) requires further optimization with respect to target size and control layout as the larger, more complex set of input data reported by the touch digitizer is used to determine the user’s intended (or most likely) target.
All UWP controls have been designed with default touch target sizes and layouts that enable you to build visually balanced and appealing apps that are comfortable, easy to use, and inspire confidence.
In this topic, we describe these default behaviors so you can design your app for maximum usability using both platform controls and custom controls (should your app require them).
