How To Measure Sink Size

Measuring the size of a sink is a simple but important task, whether you're replacing an old sink or installing a new one. The correct measurements will ensure that the new sink fits properly and functions correctly. Here's a step-by-step guide on how to measure a sink size:

1. Determine the Type of Sink

There are two main types of sinks: drop-in sinks and undermount sinks. Drop-in sinks are installed on top of the counter, while undermount sinks are installed below the counter. The measurement method varies depending on the sink type.

2. Measure the Sink Hole

For drop-in sinks, measure the size of the hole in the counter where the sink will be installed. Measure the length and width of the hole from the inside edges.

For undermount sinks, measure the size of the sink itself. Measure the length and width of the sink from the outside edges.

3. Add Required Clearance

For both drop-in and undermount sinks, you need to add a small amount of clearance around the edges of the sink. This is to ensure that the sink fits properly and prevents water from leaking.

For drop-in sinks, add 1/4 to 1/2 inch of clearance around the edges.

For undermount sinks, add 1/8 to 1/4 inch of clearance around the edges.

4. Measure the Depth

For both drop-in and undermount sinks, measure the depth of the sink from the bottom of the bowl to the top of the rim.

5. Calculate the Overall Size

For drop-in sinks, add the sink hole measurements and the clearance to calculate the overall size of the sink.

For undermount sinks, add the sink measurements and the clearance to calculate the overall size of the sink.

Example

Let's say you're measuring a drop-in sink. The sink hole in the counter measures 30 inches long and 20 inches wide. You want to add 1/4 inch of clearance around the edges. So, the overall size of the sink should be:

Length: 30 inches + (1/4 inch x 2) = 30.5 inches

Width: 20 inches + (1/4 inch x 2) = 20.5 inches

Therefore, the overall size of the drop-in sink is 30.5 inches long by 20.5 inches wide.

Tips

Here are a few additional tips to help you measure sink size accurately:

Use a tape measure or ruler that is accurate to 1/16 inch.
Measure twice to ensure accuracy.
If you're measuring an existing sink, make sure to remove any fixtures or accessories before measuring.
If you're replacing an old sink, it's a good idea to take the old sink with you to the store when purchasing a new one. This will help ensure that the new sink is the correct size and style.
