[Note] MOBILE APP的元件尺寸

今天看了兩篇文章,都談到了觸控UI元件最佳尺寸大小的定義。
單純在這邊做個筆記。

APPLE:  44dp(44x32dp)


ANDROID: at least 7 mm in size   or
                "On average, 48dp translate to a physical size of about 9mm (with some variability). This is comfortably in the range of recommended target sizes (7-10 mm) for touchscreen objects and users will be able to reliably and accurately target them with their fingers."


If you design your elements to be at least 48dp high and wide you can guarantee that:
  • your targets will never be smaller than the minimum recommended target size of 7mm regardless of what screen they are displayed on.
  • you strike a good compromise between overall information density on the one hand, and targetability of UI elements on the other.


兩者其實大同小異。
