What should be the heights of a 2-tiered kitchen countertop?

- Main Counter: Generally, the height of the main countertop is around 36 inches (91.4 cm) from the floor. This is the standard height at which most kitchen tasks, such as meal preparation and cooking, are performed.

- Upper Tier: The upper tier of the countertop is typically 6 inches (15.2 cm) above the main countertop, resulting in a height of around 42 inches (106.7 cm) from the floor. This upper tier is often used for tasks that require a bit more height, such as rolling out dough or using tall appliances like a stand mixer.

It's important to note that these measurements are standard guidelines and may vary depending on personal preferences, ergonomic considerations, and specific kitchen designs. Some individuals may prefer a slightly higher or lower countertop height to accommodate their comfort and needs.
