How to Measure for a Sink Grid

When it comes to searching for the right sink grid for your kitchen sink, the very first step is to measure the dimension of your sink in the right way.

We all want our guard to fit well and be able to do it’s purposes fully. That’s why a careful and thorough measuring may be a relatively simple process but it’s going to determine the success of your purchase and land on the right size that fits your sink.

So, how do we actually do it?

Here are the quick and simple steps that you can follow:

Step 1: Prepare the things needed

As the quote says “a short pencil is much more powerful than a human mind”. That’s why it is important to prepare the things needed and carefully jot down the acquired figures so that you will never go wrong.

Here are as follows:

  1. Paper
  2. Pencil
  3. Tape measure

Step 2: Proper position of the body

Position yourself as how you would normally stand while washing dishes. Stand in front and not at an angle. Know that all the measurements to be acquired are from this point of reference.

Step 3: Know the one inch above the bottom rule

As the sink grid will be sitting at the bottom of the sink, the sink bottom dimensions are the key parameters to determine the sink grid size.

Most sink grids in the market have a one inch height. Therefore, you need to measure the length or width of the sink bottom from the level about one inch above your sink bottom.

Step 4: Get the length size

With the use of a measuring tape, measure the left corner that is nearest to you just one inch above the bottom. Then, extend the tape all the way to the right corner which is the mirroring point. That will be the length of your kitchen sink.

For example, you have the measurement of sink bottom length 26 ⅝”, considering that there is a need of about half inch room for the grid in and out of the sink, you will need the sink grid length no more than 26 ⅛”.

Step 5: Get the width size

By the same logic, repeat the same process with step 3 but this time you will be measuring the width and that’s from the front to back of the kitchen sink.

Step 6: Locate the drain location

Once the dimension of the sink grid is determined, you need to look for the drain location of your sink. Normally, there are three locations which are the center drain, rare drain and side drain. Make sure the drain you select has the same drain location as your sink.

To get the center of the drain hole measurement, take four measurements from each of the four sides of the sink. But this time, only measure until the center of the drain.

Step 7: Know your sink’s corner radius

You must also put into consideration the curvature of the corners of your kitchen sink. If it happens that the corners of the sink grid that you purchased is too acute, then it will not have a proper fit nor become a sturdy support for your dishes and pans.

The last piece that you should be looking at is the corner of your sink. Normally, there are three corners which are 3-½” corner radius, 1-½” corner radius and zero or 3/16″ corner radius.

Make sure that the grid you select has the same or close corner radius of your sink.

How to Choose a Sink Grid

One kitchen sink would definitely not need more than one sink grid. That’s why you better make sure to pick the right one.

So, what are the factors to consider?

Quality of Steel

We advise that you choose a grid that is made from high-quality steel. This will definitely give you the quality that will surely stand the test of time. It will be hard enough to withstand bumps from the hard metals that come across it. It’s also rust-free, which makes it corrosion-free.

It is recommended that you purchase the grid that has the same grade as your sink. You can usually find a three digit number followed by some code in your sink, may it be underside or hidden from plain view. That’s the code that will indicate the grade of your stainless steel sink.

Good Welding

Opt to look for a sink grid that has the smoothest and cleanest welding on all joints. Make sure to inspect the weld-job before purchasing because the more it is jagged and bumpy, the more it is prone to grime and gunk build-up. This results in fast corrosion and hard clean up.

Rubber feet and bumpers

This is also an important factor to consider so you can fully protect your sink surface. Look for a sink grid that has feet with rubber protection and rubber edge bumpers. This is to ensure that your grid won’t scratch your sink while vigorously washing the dishes.

Grate Gaps

There are grids that have large grate gaps. But, if you’re one that throws little things in your kitchen sink, look for sink grids that have small spaces between the grate gaps.

This will make things easier for you and will prevent small things from falling through.


Take note that this is just optional. There are grids that come with coated options. This can be ideal if you want to increase the aesthetic of your sink. Some are coated with plastic that makes it non-slippery compared to plain steel. However, keep in mind that this coating tends to get worn down faster compared with plain stainless steel grids.


In summary, you need to get three things right about your sink before selecting the right grid for it. First is the sink bottom dimensions, second is the drain location and third is the sink corner radius.

Accurately getting the right measurement of your kitchen sink will enable you to choose the right sink grid for your kitchen.

On the other hand, failing to do so will lead to you being annoyed of having to go back to the store and change the size. Worse, having to buy a new one and spend money again.

Plus, with all the hustle and bustle, it will surely take your patience off of the hook.

Make sure to patiently and accurately measure your kitchen sink. Take your time doing the job. Re-check and repeat the process to fully confirm that you have the correct figures.

We hope that you have fully learned how to measure for a sink grid and find this article helpful in your grid searching.
