Choose an island size that improves the kitchen instead of stealing the room.
Use this calculator to check island length, depth, seating, and walkway clearance so the kitchen feels easier to use, not more crowded or visually heavier.
Find the island size that fits the kitchen and the movement around it
Enter the available kitchen space, current island size, seating goal, and target walkway. The tool will recommend a better island range, flag clearance issues, and show a top-down preview.
Island setup
Use centimetres. Keep the measurements approximate but realistic so the recommendation stays practical for a real kitchen.

Clearance check
WorksThe current island still leaves enough clearance for kitchen movement and daily use.
Seating note
UsableThe current island length can support the selected stool count without squeezing the ends too much.
This island size is currently workable
The island fits the kitchen in a reasonable way and should leave enough space for movement, prep, and seating without overloading the room.
Use the island calculator in the right order
The goal is not squeezing an island into the kitchen. The goal is protecting prep space, circulation, and seating without making the whole room harder to use.
Measure
Start with real walkway space
The kitchen works or fails based on movement around the island, not on whether the island looks impressive in isolation.
Decide
Be honest about seating
Adding stools changes the footprint and should only happen if the room still keeps proper kitchen clearance afterward.
Check
Review the preview and margins
Look at the plan view before assuming a deeper or longer island automatically adds more value to the kitchen.

Move into Kitchen & Dining
Once the island size is clear, solve the rest of the room around dining flow, storage, and overall kitchen function.
Refine the rest of the kitchen and dining zone with the next related tool
Once the island size is clearer, the next strongest move is usually checking the dining table, the full layout, or the spending order around the room.
Dining Table Size Calculator
Use it when the island size affects how much real space the dining table can still take without making the room too tight.
Room Layout Planner
Use it when the island decision depends on the full room footprint and not just the kitchen zone alone.
Remodel & Budget
Use it when the island is now defined well enough that you can start planning what deserves budget next.
Apply it in Kitchen & Dining
Move into the kitchen and dining hub when the island is only one part of a larger room that still needs flow and hierarchy work.
Check Dining Table Size
Use it when the island now works, but the room still needs the right dining footprint beside it.
Move into Small Spaces & Storage
Go there when the island challenge is really about making a smaller footprint work harder without crowding the room.
When the island changes the whole kitchen flow, keep the measurements and layout notes together
For people who want island options, dining dimensions, room clearances, and budget notes in one place instead of testing the room from memory.
- one place for kitchen dimensions, island options, dining sizes, and layout notes
- clearer comparison of what fits the room and what only sounds good in theory
- fewer planning mistakes caused by choosing the island before checking the full circulation logic
