Kitchen sink sizes: width, depth and cabinet fit
The right sink size depends on how you cook, the space around it and the cabinet under it. Here are the numbers to know.
Common widths
Most kitchen sinks run 24 to 36 inches wide, with 30 to 33 inches very common. Larger workstation and farmhouse sinks go wider for big kitchens. Browse kitchen sinks.
Bowl depth
Many bowls are 8 to 10 inches deep. Deeper bowls hide dishes and fit big pots but mean more bending; shallower bowls suit prep and bar sinks.
Single or double bowl
A single large bowl fits sheet pans and roasting pans. A double bowl splits washing and rinsing. A low-divide sink is a middle ground. See the kitchen sink buying guide.
Cabinet fit
The sink base cabinet has to be wide enough for the bowl and its mounting; undermount sinks usually need a cabinet a few inches wider than the sink. Check the spec sheet and use the sink cabinet fit calculator.
