The standard height of a toe kick on kitchen cabinets is typically 3 to 4 inches (7.6 to 10.2 centimeters). This measurement refers to the vertical space between the floor and the bottom of the base cabinet, allowing for a recessed area where your feet can comfortably fit when standing at the counter. However, it's important to note that toe kick heights can vary depending on factors such as personal preference, cabinet style, and the height of the individuals using the kitchen.
