HOW DO I CHOOSE A KITCHEN SINK SIZE?
Standard kitchen sink sizes may vary between design and manufacturers, so it’s 
important to know how to choosing the right sink to organized well to determine 
the correct size you need. You’ll need to measure the cabinet, countertop, and 
sink dimensions.
The kitchen sink size you choose will also depend on your budget and how much 
counter space you can spare. Remember that special features like integrated 
drainboards will take up more of this space. Keep reading to learn more about 
taking measurements and choosing kitchen sink sizes.
CABINET SIZE & COUNTERTOP GUIDELINES
Whether you are replacing your sink or renovating the kitchen, you must always 
know your cabinet and countertop dimensions. If you are only replacing the sink, 
it needs to fit the existing cutout space. And if you are renovating, you may be 
able to install a larger sink by expanding the cutout. It is not advised to add a 
smaller size sink to your existing countertop.
Correct measurements are very important to ensure that enough space is 
allocated for the faucet, fixtures and other materials behind the sink. For 
example, if your overhead cabinets hang low, you’ll want to stay away from 
faucet necks that are too high. Your installer will also consider the bowl depth to 
ensure there is adequate space underneath.
How to determine the minimum cabinet size
Measure the cabinet size under the existing sink or where the new sink will go.
Measure from gable to gable (left to right). See diagram.
Be sure to measure from outside edge to outside edge.
To save time, double check your measurements.
This is the "Minimum Cabinet Size", and this size is noted next to each sink model 
in the BLANCO catalogue. Standard kitchen cabinets come in size increments of 3"
(for example: 18", 21", 24", 27", 30", 33", 36" etc.).
How to measure the depth of your countertop
The width (front-to-back measurement) of the sink that can be used is 
determined by this measurement.
DROP-IN SINKS:
For laminate countertops with a backsplash, you can install a drop-in sink that is 
up to 20 1/2" deep.
For laminate or stone countertops without a backsplash, you can install a sink that
is up to 22" deep
UNDERMOUNT SINKS:
Consult your installer. These measurements are important to ensure that enough 
space is allocated for fixtures and backsplash material behind the sink.
UNDERSTANDING KITCHEN SINK DIMENSIONS
The standard sink size is about 22 inches long to 30 inches wide, but once again 
it’s crucial to take proper measurements. If you’re replacing a drop-in sink with 
rims, start measuring from the outer lip of the sink, not the basin itself. If you 
have an undermount sink, start measuring where the edge meets the counter.
KITCHEN SINK LENGTH:
This is how far a sink extends along the countertop. Fix your measuring tape to 
the left edge of the sink and stretch it over to the right. The standard length is 30-
33 inches, but varies whether you have 1 or 2 bowls. Some double bowl models 
range up to 48 inches. A single bowl sink will have one basin. A double bowl has 
two basins side by side, so you can use one bowl to set dirty dishes and the 
opposite bowl for washing dishes by hand or rinsing produce.
KITCHEN SINK WIDTH:
To find the width, measure from the back edge of the sink to the front edge. The 
standard size is 22 inches.
KITCHEN SINK DEPTH:
Find your sink’s depth by measuring the top edge of the sink down to the bottom. 
The standard depth is around 8 to 10 inches. Anything shallower than 8 inches 
will make it difficult for you to have enough space to wash dishes. The extra depth
can make it easier to wash oversize pots, which is helpful for anyone cooking for a
big family or entertaining guests.
