How To Measure Kitchen Countertops

New counters can make a tired kitchen look new again. Most fabricators will use templates to get the accurate size and shape of your counter, but measuring it beforehand is also a good idea for determining how much you’ll spend or what materials you’ll need to do the job yourself.

Take measurements for your new countertop quickly with these tips and get started on your DIY project today!

Measuring Kitchen Countertops

Countertops are measured after they are installed and all the appliances, sinks, and faucets have been put in. If you’re just replacing the countertop with one that has an existing size or shape that matches your measurements, then you can use its current dimensions as a basis for measuring out new counters.

Make sure there is enough room for your sink’s spout and handles to go through by checking when measuring.

  • Determine the shape of your countertop.
  • Measure the length and width of your countertop.
  • Add these two measurements together to determine the total square footage of your countertop.
  • If you are ordering a countertop, use these measurements to order the correct size.
  • If you are DIYing, use these measurements to buy the correct amount of materials.

Remember that for most counters, you will need a ¾” backsplash. When measuring for your new counters, be sure to account for this as well!

How To Measure Kitchen Countertops

Making A Simple Sketch

If you are replacing an existing countertop or have a very specific size and shape in mind, you can make a simple sketch to give to the fabricator. This will ensure that your new counters are made to fit exactly as you want them to.

Be sure to include the following information on your sketch:

  • The length and width of the countertop
  • The shape of the countertop
  • Where the sink(s) and appliances will go
  • Any cutouts that will be needed, such as for a cooktop or range hood
  • Any special features, like a curved front edge or added molding

Once you have your sketch, take it to your fabricator and they will create a template for your new counters.

Countertop Layout

If you’re not sure how your appliances will fit on your new counters, you can use a countertop layout to help visualize the space. This is especially helpful if you’re planning to move or replace any of your appliances in the near future.

Simply print out a blank countertop layout and draw in the approximate location of each appliance. You can then cut out the shapes of each appliance and move them around until you find the best placement. This will also help you determine how much space you’ll need between each appliance.

Once you have a layout that you like, take a picture of it and send it to your fabricator. They can use it to create a template for your new counters.

Measuring Your Countertop Dimensions

If you’re not replacing your countertops, but are simply installing a new one, you’ll need to measure the dimensions of your existing counters. This will ensure that the new countertop is the correct size and shape.

  • Measure the length and width of your countertop at its widest points.
  • Measure the depth of your countertop from front to back.
  • Take into account any overhangs or extensions that may be on your current countertop.
  • Add these three measurements together and write them down.

This is the size that you will need to order for your new countertop.

Indicating Sink, Stove, And Finished Edge Locations

If you are ordering a pre-made countertop, you will need to indicate the location of your sink and stove. This can be done with a simple diagram or by using measurements.

Be sure to mark the location of your finished edge as well. This is usually at the back of the countertop, but maybe on a side if you have a curved front edge.

If you are DIYing, these markings will help you when cutting your countertop to size.

Template For The Sink Cutout

If your sink is not rectangular or square, you will need to provide a template for the cutout. This can be done with a piece of cardboard or heavy paper. Simply trace around the outside of your sink and cut out the shape.

Measuring Odd-Shaped Countertops

The basic process is that you measure the length and width of your countertop at several points, find a few reference points on it, and use those to draw a shape.

for example, let’s say you have a counter that is L-shaped, and the long part is 4’x10′, and the short part is 2’x5′.

The fabricator will need to know the dimensions of the L-shape, so you’ll need to measure it as follows:

Important Things To Keep In Mind

You should always measure twice, just to make sure your drawing is accurate.

Slab Size

Countertops are typically manufactured in 3’x6′ or 3’x8′ slabs. If your countertop is wider or longer than those dimensions, it will need to be pieced together from multiple slabs.

This means that the seams where the slabs meet will be visible. If this is not something you want to see, your kitchen countertop will need to be made to size.


The depth of a countertop can vary slightly, so it’s always best to measure the depth at its deepest point. This will ensure that your new countertop is not too shallow or too deep.

Overhangs And Extensions

Many countertops have overhangs or extensions that add extra width or length. If your countertop has these, be sure to measure them and include that information in your drawing.

Finished Edge

If you have a finished edge on your current countertop, be sure to mark where it is on your diagram. This will help the fabricator when creating your new countertop.

There you have it – everything you need to know about measuring your countertops! Remember to double-check your measurements, and if you have any questions, don’t hesitate to ask a professional.
