As I was talking about the Fitts’ Law, I thought it might be good to go through some basics but golden rules. Today’s video is about the size of the action button. It is also following the marginal effect as a 20% size increase could significantly reduce the speed that users use to click the target button. But bigger is not always better. It has been found that buttons that are too big are somehow taking even more time to reach. So you might want to hit something in between. The golden size.
