For an 8-foot ceiling, the standard height for kitchen cabinets is usually around 30 to 36 inches (76 to 91.4 cm) from the countertop to the bottom of the wall cabinets. This height allows for comfortable access to the upper cabinets while leaving enough space between the cabinets and the ceiling to avoid a cramped feeling in the kitchen.
Here's a typical configuration for kitchen cabinet heights with an 8-foot ceiling:
Base Cabinets: The base cabinets are usually 34.5 inches (87.6 cm) tall, excluding the countertop thickness. The countertop typically adds another 1.5 inches (3.8 cm), resulting in a total height of 36 inches (91.4 cm) from the floor to the top of the countertop.
Wall Cabinets: The wall cabinets are installed above the base cabinets, starting at a height of 54 inches (137 cm) from the floor. This gives a clearance of 18 inches (45.7 cm) between the countertop and the bottom of the wall cabinets.
Total Cabinet Height: The total height of the base cabinets and wall cabinets combined is usually around 90 inches (228.6 cm), leaving about 18 inches (45.7 cm) of space between the top of the upper cabinets and the ceiling.
Remember that these measurements are standard guidelines, and you can adjust the height based on your personal preferences and specific needs. Additionally, if your ceiling is slightly higher than 8 feet or you want to create a more custom look, you can consider adding crown molding or a soffit above the upper cabinets to fill the space between the cabinets and the ceiling.
