How much space do you need around a kitchen island?

Common guidelines call for 36 in minimum for a walkway, 42 in between the island and counters for one cook, and 48 in for two cooks. Allow about 44 in behind seated guests if people need to pass.

What is the minimum kitchen size for an island?

Roughly 12 × 13 ft for an L-shaped kitchen with a small island. Below that, a peninsula or rolling cart usually works better.

How big should a kitchen island be?

Most islands are 2–4 ft deep and 4–10 ft long. Deeper than about 4.5 ft makes the middle hard to reach unless there's seating access from the far side.

How much overhang do I need for seating?

About 15 in of knee space at a 36 in counter and about 12 in at a 42 in bar. Allow 24 in of width per stool.

How many pendants over an island?

Usually two for islands up to about 5 ft, three up to about 8 ft, and four beyond that, hung 30–36 in above the counter and spaced evenly.

Plan outlets with your electrician; many local codes require at least one on an island.

How the island size is calculated

Each wall with cabinets takes about 25 in of counter depth plus the clearance you choose. Walls without cabinets keep a 36 in walkway, and a seated side facing the room keeps about 44 in so people can pass behind the stools. What's left is the space for your island, capped at a reachable depth (4.5 ft, or 5.5 ft with seating on both sides). Seating needs knee space: 15 in at counter height, 12 in at bar height.
