What You Will Need

Before we tackle how kitchen sinks are measured, let us first go through the things you will need for this process. These are just some basic things you likely already have on hand.

  • Pencil: A tool to mark down and write your measurements.
  • Paper: Take down your kitchen sink dimensions and any notes you need to remember.
  • Tape Measure: This is essential for getting accurate measurements of your kitchen sink area.
  • Level: This is to ensure evenness and alignment.

Now, with these simple tools, we can begin the process of how to measure a kitchen sink.

Know What Type of Sink You Are Measuring

Knowing how to measure a kitchen sink is not as straightforward as it sounds. We begin by looking at the different sink options. Each type of sink comes with unique characteristics, and understanding the differences is important to get accurate measurements.

  • Undermount sinks: These sinks are attached at the bottom of the countertop to give a sleek finish. How to measure for an Undermount Sink? When measuring, add a buffer to include the measurement of your countertop.
  • Drop-in sinks: These are also known as top-mount sinks. How to measure a drop-in sink? Since these are inserted into a pre-cut hole in the countertop with the rim resting on top, you have to make sure the countertop cutout’s dimensions are precise for a snug fit for your drop-in sink.
  • Farmhouse sinks: Compared to other types, these sinks have a deeper basin with an open front. These sinks are popular for their large space and unique look. Since farmhouse sinks have a deeper basin, you will need to accommodate the size and know how to measure cabinet size for your kitchen sink.

Knowing these types of sinks and their distinct characteristics will help you learn how to properly measure a kitchen sink.

Prepare Your Kitchen and Measure

Before starting, it will be best to make sure everything is prepared to avoid any problems when getting your kitchen sink measurements.

  1. Clear your kitchen base cabinet: Remove any clutter from your cabinet to give you enough space to work and get accurate measurements.
  2. Ensure your sink is clean: You do not want to make a mess while measuring your kitchen sink. Remember, a clean and clear workspace is key to getting accurate measurements.
  3. Double-check all measurements: Accuracy is critical! Remember to repeat your measurements to make sure they are consistent.
  4. Follow specific measurement guidelines: Be aware of the type of sink you are measuring for. Be sure to follow the guidelines provided
  5. Follow specific measurement guidelines: Different sink types may have specific installation requirements, so be sure to follow the guidelines provided when measuring your kitchen sink.

Knowing how to measure a kitchen sink requires accuracy and precision. Be mindful of your workplace and information to avoid problems during your installation.

How Are Kitchen Sinks Measured?

Getting accurate kitchen sink measurements is the first step to your dream kitchen. The following steps will help you know how to correctly measure a kitchen sink.

  1. Start with the edge: When measuring, begin with the lip or the edge that overlaps with the countertop. For undermount sinks, include in your measurements the countertop where the sink will be mounted. This will give you your complete kitchen sink dimensions.
  2. Measure the length: To measure your kitchen sink’s length, run your measuring tape or ruler from the left edge of the sink all the way to the right edge. Record the length. Make sure your measuring tape remains straight when moving.
  3. Measure the width: To measure your kitchen sink’s width, place your measuring tape on the edge nearest the faucet. Then, follow the sink vertically to the front edge.
  4. Measure the depth: To measure the depth of your kitchen sink, place a straightedge rule or level across the top of the sink, ensuring it sits evenly. Use your measuring tape to measure from the deepest point of the sink to the bottom edge of your ruler. Record the depth. Knowing the depth of the sink is important in choosing compatible plumbing fixtures.
  5. For undermount sinks: Do you remember how to measure an undermount sink? Don’t forget to include in your measurements the countertop surface where the sink will be placed. This measurement will make sure that there is enough clearance for installing the sink beneath the countertop.
  6. For farmhouse sinks: For farmhouse sinks, always measure from the top edge to the bottom of the exposed front to get the precise depth. This depth may differ from the basin depth. Correctly taking this measurement will ensure your sink fits perfectly into your cabinet and aligns properly with the surrounding fixtures.

These tips are helpful when knowing how to measure a kitchen sink. These will help you get a precise measurement, taking you one step closer to your dream kitchen.

Measure Your Cabinet Space

Learning how to measure a kitchen sink will also include measuring your cabinet space. This is particularly important when knowing how to measure for a replacement kitchen sink, as the existing cabinet space will determine the maximum size of the sink you can install.

 

  1. Measure the cabinet’s depth: Place your tape measure on the bottom part of the cabinet and take the measurement from the back to the front edge.
  2. Measure the cabinet’s total width: For your cabinet’s width, place your tape along the cabinet’s bottom, measuring from the left edge to the right edge.
  3. Calculate your sink’s width: The recommended width for your sink is 4 inches less than the total width and 1 inch less for the depth. This adjustment makes sure that your sink will fit snugly within the cabinet while leaving space for proper installation and access.
  4. For drop-in sinks: If you are installing a drop-in sink, measure the interior width at the widest point of the sink, then subtract 4 inches to get the suitable cabinet space for your sink.
  5. Replacing a farmhouse sink: If you are upgrading from a farmhouse sink, remember to measure the height of the exposed front of your old sink. This measurement will represent the maximum depth of your new sink.
  6. First-time installation of a farmhouse sink: For a new farmhouse sink, access the inside of the cabinet by removing the false drawers. Your measurement should be from the top of the counter to the edge of the cabinet door. Deduct 1 inch to serve as your buffer. This will determine the maximum depth of your new sink. Measuring your available cabinet space is an important step, as this will help you choose the appropriate sink for your kitchen space.

Measure the Cutout

Aside from the cabinet space, another factor that can affect your choice of kitchen sink is the cutout. A cutout is the countertop opening where you will fit your kitchen sink. Measuring your cutout will determine the compatible kitchen sinks for your kitchen.

  • Measure the area: After removing your old sink, measure the area as previously instructed in step 1. Start by measuring from side to side, followed by front to back. This is the total width of your new sink.
  • Consider the corners: Make sure the corners of your cutout and the lip of your new sink align to cover all the gaps completely.
    For undermount sinks: If you’re installing an undermount sink, ensure that the cutout matches the new sink’s interior measurements.
  • For a drop-in sink: Consider the necessary overlap between the lip and the counter during installation for a drop-in sink.

Accurate measurements of your cutout will help you in various ways. Aside from a hassle-free installation, it will help you choose a sink easier. You can easily find a kitchen sink by your cutout size.
