On the mobile devices, Material Design Guidelines also suggests limiting the duration of animation to 200–300 ms. As for tablets, the duration should be longer by 30% — around 400–450 ms. The reason is simple: the size of the screen is bigger so objects overcome the longer path when they change position. On wearables, the duration should be accordingly 30% shorter — around 150–200 ms, because on a smaller screen the distance to travel is shorter.
