How much space do you need around a kitchen island?

Short answer: leave 100–120 cm of clear floor between the island and the counters or wall opposite. 90 cm is the minimum for one cook; go to 120 cm if two people cook together or if a dishwasher or oven door opens into that aisle.

Why the doors decide

An open dishwasher or oven door sticks out about 50–60 cm. With a 90 cm aisle there is no room left to walk past it, so the busiest side of the island needs the most space.

How big should the island be?

To be useful an island needs a worktop of at least about 100 × 60 cm. If people will sit at it, add a 25–30 cm overhang for knees and allow about 60 cm of width per stool. A counter-height island (90–92 cm) pairs with stools of about 65 cm seat height.

Is the kitchen big enough?

A rough check for a one-wall kitchen plus island: 60 cm counter + 110 cm aisle + 100 cm island = about 2.7 m, plus around 90 cm behind the stools if the island has seating. With counters on both sides you need roughly 4.2–4.4 m across.

Plan the services early

A sink or hob on the island needs water, a drain or an extractor planned before the floor is laid, and sockets on the island must follow your local wiring rules. If the space is tight, a peninsula or a slim table-style island on legs often works better than squeezing in a full one.

In our Sage Green Kitchen Renovation we drew two layouts first and checked every clearance in plan before choosing the island size.
