An island is decided by the space around it, not by the space it occupies. Get the clearances right and it makes the kitchen work better. Get them wrong and it is a beautiful obstacle you edge around for the next fifteen years.
Thirty six inches is the absolute minimum walkway around an island, and it is a number to design away from rather than toward. Forty two to forty eight is what actually feels comfortable, and near a sink, a dishwasher or an oven it is what you need for the door to open and someone to stand at it.
That is why the island is the last thing sized, not the first. We measure the room, subtract the clearances the working sides need, and whatever rectangle is left is your island. Squeezing an extra six inches of worktop out of a walkway is a trade people regret quickly.
Where the arithmetic does not leave enough, the honest answer is a peninsula or a longer run instead. We say so rather than build something that makes the kitchen worse. See custom cabinets, the custom hub and quartz worktops.

How it works
How an Island Gets Sized
Measure the room empty
The island is whatever is left once every working side has its clearance. We mark the footprint on the floor with tape so you can walk it before anything is ordered.
Decide what it carries
A sink or a hob in the island means plumbing or a duct run and changes the clearances on that side. Storage only is simpler and cheaper, and worth considering honestly.
Set the overhang and stools
Overhang depth is chosen against the stools you actually want. Backless need ten to twelve inches, stools with a backrest twelve to fourteen. Width per seat is set at the same time.
Support, then build
Stone beyond twelve inches of overhang gets corbels or legs, specified before the worktop is templated. Then the island is built with the rest of the cabinetry and installed level to the floor.
Seating that works
Why Most Island Seating Never Gets Used
The usual failure is overhang. Ten inches is the minimum anyone can tuck their knees under, twelve is comfortable for daily use, and fourteen to fifteen suits long sittings. Below ten, people perch sideways and stop using the seats, which is how a three-stool island ends up with three ornaments on it.
Width per stool is the other half. Nineteen and a half inches is the minimum and twenty two to twenty four is comfortable, so a run that fits three stools on paper often seats two people happily. Behind them you need thirty six inches to get in and out, and forty five to sixty if a walkway passes there.
Stone overhangs beyond twelve inches want corbels or legs underneath, which changes how the island looks and has to be decided with the worktop rather than after it. Pull-outs and drawer organisation go into the closed side.

The Rest of What We Build
An island is one piece of a custom kitchen. These are the others.
Clearances, seating, services and when a room is simply too small.
Thirty six inches is the minimum walkway and forty two to forty eight is what feels comfortable. Near a sink, dishwasher or oven, aim for the higher end so the door opens and someone can stand there.
Ten inches is the minimum for knees, twelve is comfortable for daily use and fourteen to fifteen suits longer sittings. Below ten, people sit sideways and the seats stop getting used.
Allow at least nineteen and a half inches of width per stool, and twenty two to twenty four for comfort. A run that fits three on paper frequently seats two people happily in practice.
Beyond twelve inches in stone, yes: corbels or legs. That has to be decided with the worktop rather than discovered at templating, because it changes how the island looks from the seating side.
Yes, though both add cost. A sink means plumbing and drainage under the floor, a hob means a duct run for extraction. Both also increase the clearance that side of the island needs.
Then we say so. A peninsula attached to a run, or simply more storage along a wall, beats an island that makes the room awkward. An island is not a requirement for a good kitchen.
Thirty six inches to get in and out comfortably. If a walkway passes behind the seating, forty five to sixty, because otherwise anyone seated has to move every time someone crosses the room.
We tape the outline on your floor and open every door around it before a single cabinet is quoted. It is the cheapest way to find out whether the size is right.
