A kitchen island can become the heart of the home: prep space, storage, breakfast bar and homework station in one. A badly planned island, on the other hand, blocks circulation and makes cooking harder. Planning comes down to a few measurements.
Do you have the space?
The most important number is clearance. The National Kitchen & Bath Association (NKBA) guidelines recommend aisles of at least 42 inches for one cook and 48 inches for two cooks around an island. If your kitchen cannot provide that, consider a peninsula, a rolling cart or a narrow table instead.
Size and shape
A minimum useful island is about 2 by 4 feet. Larger islands can host a sink or cooktop. Keep the island in proportion to the room; very long islands may need a break in the middle for circulation.
Seating
- Allow about 24 inches of width per seat.
- Overhang: around 12 inches at counter height (36 inches), 15 inches at bar height is more comfortable.
- Choose stools with a seat height about 10 to 12 inches below the countertop.
Function: sink, cooktop or open prep?
- Prep island: the simplest. A large empty surface for cooking, baking and serving.
- Sink island: you face the room while washing up; needs plumbing and a place for the dishwasher.
- Cooktop island: social for the cook, but requires ventilation (a hood or downdraft) and is less safe with children sitting nearby.
Storage
Deep drawers for pots and pans, a cabinet for small appliances, open shelves for cookbooks at the seating end, a trash and recycling pull-out, and even a microwave drawer.
Power and light
Building codes generally require electrical outlets on islands; plan them so you can plug in a mixer or laptop. Pendants are usually hung about 30 to 36 inches above the counter, spaced evenly. See how to choose the right lighting.
Materials and style
The island is an opportunity for contrast: a different cabinet color (dark green, navy, wood) or a different countertop, such as wood on the island and quartz around the perimeter. Countertops are compared in how to choose the right kitchen countertop material.
