Traditionally, a coffee bar is about 40 to 43 inches tall. This is taller than the average kitchen countertop, making it easier to perform detailed tasks like grinding coffee beans or creating latte art.
Keep in mind that this is just a general rule. There is nothing wrong with a coffee station that is shorter or taller than this height. It’s far more important for the bar to be comfortable for the coffee lover who will be using it every morning!
