Displaying minimum and maximum values on a slider gives users a clear understanding of the range they're working with. In left-to-right languages, you'll typically find the minimum value on the far left and the maximum value on the far right. For right-to-left languages, just flip that orientation.

Including these values is especially crucial when the slider represents a set of numbers or quantities that aren't intuitively obvious. For example, if you're adjusting settings like brightness or volume, you might not need exact numbers. But when dealing with figures like prices or time durations, showing the minimum and maximum limits helps users make more informed decisions. It's all about clarifying the user's choices and setting clear expectations.
