The most comfortable height for users to hold the pot handle should be an important criterion for determining the height of the table top, which is generally 65-90 cm. The method to determine the optimal height is: the operator's forearm is lifted horizontally, and the height from the elbow back to 10- 15 cm is the optimal height of the table top.

Because the user's height is different, the kitchen countertop should be adjusted according to the user's height and the cooking of Chinese food or western food. For example, the iron pot for Chinese food and the pan for western food have a height difference of 10 cm.
