Kitchen Island Dimensions
Kitchen island dimensions can be tricky. It's easy for an island to get out of hand in relation to the space where it will be installed. Catch mistakes with kitchen island dimensions early in the design process.
More than once customers have contacted me about kitchen designs, and declared that they wanted an island. Once I get the floorplan in hand though, I realize there there the kitchen island dimensions they were thinking will just not work. "There's plenty of room," they say. "We've got ten feet!" And then I have to break the news that it will be a small island indeed. Sure there's ten feet of room, but four feet will be chewed up by the cabinets along each wall (normal base cabinets are two feet deep) and the kitchen island dimensions they were thinking (three feet deep by, say, four feet long) will give a total of three feet for walking.
That's fine, except that there needs to be walking space on both the front and back sides of the island. A foot and a half is not going to pass muster with the kitchen design police… This is an illustration of that exact scenario. Black is the walls, blue is the set of perimeter cabinets, and red is the proposed kitchen island dimensions. Not going to work. With each square representing six inches, you can see there are 18 inches of clearance on the front and back of the island cabinets. While you can go less, I think four feet is about right for walkways. Using that as a guide, there is no room in this kitchen for an island. Rather than ten feet of space, you ought to have about fifteen feet for this kind of setup.
Even then though, there'd still be no real room for seating at the island. If there were enough space once the parallel runs of cabinets finished (down at the bottom of the drawing) it might be possible to put an island out in that space. More than likely though, in a plan like this, that area is the dining room.
What are Ideal Kitchen Island Dimensions?
Sorry, there really aren't any. There are, however, some things to consider…
Kitchen Island Depth: Symmetrical looks better. Whatever depth you're going with, get two panels of equal size on the ends. I've seen a three foot island where a wall cabinet, placed on the floor, was back to back with a base cabinet. Each cabinet had a paneled end, but when you look at the island form the side, one panel is 24" wide (the base cabinet), and the other is 12" wide (the wall cabinet. To each his own, but I think it looks weird. That island might have been better if there were one big panel (just flat plywood 3 feet wide) with a couple of 15" wall cabinet doors (30" high) stuck on the end.
Kitchen Island Length: Whatever toots your horn. Pretty much whatever you need for space, balanced with what will fit in the kitchen, is what works.
Kitchen Island Height: Normal island height is 34 1/2 inches (just like regular base cabinets — but remember that this does not include the countertop thickness) but there's nothing stopping you from going higher or lower with it. Most people, if their going to vary, will go higher. This way they can sit comfortably on bar stools. Some folks will go lower, making their island into a kitchen table with storage.
Whatever kitchen island dimensions you decide on, just make sure there's enough room to get around it. And remember to include the total countertop size when figuring the footprint that the island will make in your kitchen.
