Why Is Kitchen Sink Size Important?

Having the wrong kitchen sink sizes can increase the chances of back pain because you might have to bend more to clean your dishes in the sink. Besides that, you may get broken dishes due to the fact that your sink becomes overcrowded after washing a few dishes.

Choosing the right sink size will help you prevent back and neck pain, keep the dishes from breaking, and make the most of the space you have. Besides that, kitchen sink cut out size is also important for house sellers. The kitchen is an important room in a house, so making changes to it can add significant value. Even though it’s a small detail, buyers will probably look into the kitchen sink dimensions prior to making an offer.

How Kitchen Sinks Are Measured?

Kitchen sinks are typically measured by their overall dimensions, including the length, width, and depth of the basin(s). Here are the steps for measuring a kitchen sink.

  • Empty your kitchen base cabinet so you can measure the space with a clean surface.
  • Make sure that your sink is free of dishes and clean.
  • Start by measuring the edge of the kitchen countertop with your measuring tape or a ruler. If you have an undermount sink, measure from the counter opening’s edge.
  • Place the edge of your tape measure on the left edge of the sink and stretch it across to the right edge to get the length of your sink.
  • Place the tape measure at the back edge of the sink (closest to the kitchen faucet) and stretch it across the sink basin to the front edge to get the sink’s width.
  • Put your level or straightedge ruler across the top of your sink. Use a tape measure to determine the distance from the deepest portion of your sink’s basin to the lowest edge of the ruler to get the sink’s depth.
  • Take all of your measurements twice to make sure they are correct.
  • Measure the distance between the center of the left faucet hole to the center of the right faucet hole to note the faucet holes.
