Very cool kitchen with curved orange breakfast nook.If you’re putting in a kitchen island, there are quite a few dimensions you need to pay attention to.  Those dimensions include height of the island and distance on all sides.  You don’t want your kitchen aisles too narrow.

To that end, we put together 4 custom kitchen island dimension diagrams that set out proper distances and height for islands that seat 2, 3, 4 and 6 people.  Check out the four diagrams below.

Standard Dimensions:

  • Island height: 42″
  • Island depth: 42″ (with a sink).  You can make islands narrower without a sink.
  • Length:  See below – length is main dimension that changes based on number of seats.
  • Space per stool: 24″
  • Kitchen Stool height: 30″
  • Kitchen island surface to bottom of over-island light (i.e. bottom of pendant light): 36″
  • Distance between pendant lights: 30″
  • Height from stool seat to kitchen island surface: 12″
  • Distance from end stool to end of island: 9″
  • Clearance distance on all sides of the island:  36″ minimum.  You want a minimum of 30″ from any point of the island to any other point such as a cabinet, wall, appliance so you have sufficient room to move around.
  • Counter surface to upper cabinets: 18″
  • Counter height: 36″ (notice a standard kitchen island height is higher than the counter).

    It would be helpful to have the dimensions of each island shown in the pictures. I am looking for 5ft. long quartz table 24 inches wide to put in front of two standard size windows.
