Average Counter Space In Kitchen. Countertops are one of the most important components of a kitchen remodel. When a countertop or island doubles as a seating area a 28- to 30-inch-wide space per diner is most comfortable.
In case you cant envision it 30 square feet has an area of 548 feet by 548 feet. Once kitchens took up just 100 to 150 square feet. And quite honestly being on an island you really need a lot more for safety.
You need a minimum of 15 on the outside edge of your cooktop.
If you are much shorter or much taller the design standards might not be ideal for you. Bare minimum prep space is 30 and as noted more is better. Allow 18 to 36 inches 45 to 92 centimeters of countertop space on one or both sides of your sink. I think 15 inches is the absolute minimum.
