Visualize My KitchenThis calculator estimates island size and clearance from your kitchen's overall footprint, assuming standard 24 in perimeter counters and a walkway on each side of the island. Actual layouts depend on door swings, appliance placement, and plumbing runs — use this as a starting point, not a final measurement.
