Kitchen islands provide extra workspace and sometimes house the cooker hob or a sink. Some islands also have room for bar stools and an eating space. The correct size of a kitchen island depends on its surroundings.
A properly-sized island can make the difference between a functional and an exasperating kitchen. The island affects the kitchen's traffic flow and convenience, and must be carefully planned.
The National Kitchen and Bath Association (NKBA) recommends that the space between the island and adjacent counters or appliances should be at least 105 cm (42 inches) for one cook and 120 cm (48 inches) for two or more.
Walkways that pass by the island but aren't part of the kitchen workspace should be at least 90 cm (36 inches) wide. If the walkway is behind an island seating area, it should be 110 cm (44 inches) wide for easy passage.
Islands should not interfere with a kitchen's work triangle, an imaginary line from the hob to the sink to the refrigerator. The NKBA says cooks should not have to walk more than a 30 cm (1 foot) around the island to get from one work area to another.
Tim Carter, a builder and nationally syndicated columnist, suggests the maximum island size should be 1.8 m (6 feet) deep and 3 m (10 feet) long.
