Will an island fit in my kitchen?
Type your room size and where the fitted units go. The planner works out the biggest island that leaves a comfortable walkway all round, how many stools it seats and what to change if it does not fit.
Your result
Type your room size above.
Seen from above, in proportion. Green: fitted units. Peach: island, paler where the worktop overhangs. Circles: stools. Green pills: walkway widths in mm.
How the planner works it out
Island length = room length − walkway at each end Island depth = room width − fitted unit depth − walkway each side Stools = island length ÷ 600 mm, rounded down
With an L or U layout the units on the side walls are taken off the length too. If the hob or sink is in the island, the walkway on the cooking side goes up to 1200 mm so a second person can pass behind the cook safely. The planner never makes the island deeper than 1200 mm or longer than 3000 mm, because beyond that you cannot reach the middle of the worktop and one piece of stone becomes hard to get into the house.
Sizes that usually work
| Room | Island | Seats | Verdict |
|---|---|---|---|
| 3600 × 3400 | 1600 × 800 | No stools | Prep island only; too shallow for knee space |
| 3800 × 3600 | 1800 × 1000 | 3 stools | Compact but comfortable |
| 4200 × 3600 | 2200 × 1000 | 3 stools | Comfortable |
| 4800 × 3900 | 2800 × 1200 | 4 stools | Generous |
| 3600 × 2900 | none | - | Choose a peninsula or table |
For standard island sizes, worktop heights and the 60 cm question, read the kitchen island dimensions guide. For whole-room sizes, see kitchen measurements.
Questions
- How big a kitchen island can I fit?
- Take the room length and subtract a walkway of at least 900 mm, ideally 1000 to 1200 mm, at each end. For the depth, take the room width, subtract the depth of your fitted units and two walkways. If the depth left is under about 600 mm, an island will not work and a peninsula is the better choice.
- How much space do I need for stools at an island?
- Allow about 600 mm of island length per stool and an overhang of 250 to 300 mm at worktop height so knees fit under. Behind the stools leave around 1000 mm if people need to walk past.
- What is the minimum room size for an island?
- With units along one wall and 1000 mm walkways, the room needs to be about 3.2 m wide for a 600 mm deep island with no stools, and about 3.5 m wide for a 900 mm deep island with stools on one side. Length matters too: allow at least 3 m so the island can be 1 m long. The planner works out the exact figure for your layout.
