How to Measure for Quartz Countertops

Measuring for new quartz countertops is an important step to ensure that your new counters fit properly and look their best in your kitchen or bathroom. With some careful planning and precise measurements, you’ll be ready to install your beautiful new quartz countertops.

Why Accurate Measurements Are Crucial

Quartz countertops are custom cut to fit your existing cabinetry and layout. Unlike prefabricated countertops that come in standard sizes, quartz counters are made specifically for your space. Even small measurement mistakes can result in gaps, overhang problems, and a poor fit.

Taking the time to measure correctly will ensure:

  • The countertops fit snugly against the walls with no gaps.
  • Overhangs are the right depth. Standard is 1 1⁄4”.
  • Seams between slabs are minimized.
  • Cutouts for sinks, cooktops, and other fixtures are accurately placed.

Accurate measurements allow the fabricator to cut the slabs and make cutouts with precision. This results in a beautifully installed quartz kitchen or bath countertop.

Measuring Tools Needed

Having the right measuring tools on hand will make getting accurate measurements much easier:

  • Tape measure. A 25-foot retractable tape measure is best. Make sure it is still accurate and not loose or worn.
  • Straight edge. A 4-foot level or another straight edge will help mark straight lines.
  • Pencil and eraser. Mark measurements in pencil so you can correct mistakes.
  • Markers. Different color sharpies can help distinguish different measurements.
  • Wooden yardstick. Useful for measuring inside cabinetry.
  • Digital caliper. Helpful for very precise measurements if needed.
  • Notebook. Record all measurements for easy reference.

Steps to Measure for Quartz Countertops

Follow these steps to get all the necessary measurements for your fabricator:

1. Clear Countertops and Sink Area

Remove everything from the existing countertops and clear a 4-foot radius around the kitchen or bath area. This gives you ample room to maneuver and take measurements.

2. Measure Overall Dimensions

  • Length – Measure the overall length of the countertop space. Take measurements from the corners. Record the exact dimensions.
  • Width – Measure overall width at the front and back. Also measure width at any bump outs or changes in dimension.
  • Overhangs – Standard overhang for quartz is 1 1⁄4”. Measure existing overhangs if different.

3. Check for Level

Verify countertops are level. Use a 4-foot level placed against cabinets on all sides. If not level, measure from the highest point (usually at a wall). Make a note of any sloping.

4. Measure for Sink Cutouts

  • Trace the exact outer shape of the sink rim with a pencil on the existing counter.
  • Measure the sink front to back and side to side.
  • Note the location of the sink hole from corner(s).
  • Specify undermount or topmount sink installation.

5. Measure Appliance & Fixture Cutouts

  • Trace out the perimeter of cooktops, ranges, and any other appliances that will need cutouts in the quartz.
  • Measure dimensions of traced areas.
  • Note the exact location of each cutout area.

6. Check Inside Cabinets

Use a wooden yardstick to measure inside cabinet dimensions under countertops. Check areas with dishwasher and stove cutouts especially.

7. Note Thickness of Existing Counters

Quartz thickness will be based on existing countertop thickness. Standard is 1 1⁄4” but measure yours to be sure.

8. Measure & Note Any Special Details

  • Location of holes for plumbing fixtures like soap dispensers.
  • Dimensions of corners – tight 90 degree or angled?
  • Edge details – standard eased edge? Bevel? Ogee?
  • Seams – where you would prefer seams placed.
  • Backsplashes – measure height and length.

9. Describe the Job Completely

Provide the fabricator a complete description of the job, including:

  • Kitchen or bathroom to be replaced
  • Sink specifications – undermount or topmount
  • Appliances getting cutouts
  • Counter thickness
  • Edge profile desired
  • Backsplash measurements
  • Drawings and diagrams of layout

10. Double Check All Measurements

Carefully review all measurements and details taken to ensure accuracy before submitting to the fabricator. Having accurate measurements will make installation smooth and trouble-free.

FAQs about Measuring for Quartz Counters

How precise do measurements need to be?

Within 1/16″ is best. The more precise the better for an accurate fabrication.

What if walls or cabinets are uneven?

Make note of any uneven areas and measurements. The counters can be scribed to walls during installation.

Can I measure just the countertop area?

No – overall room dimensions are needed. Photos of the full space are also very helpful.

What if I miss something in my measurements?

Review measurements thoroughly. The fabricator can usually tweak small details during templating. But any major issues could mean a delay.

How are seams and joints determined?

The fabricator designs seams based on measurements, traffic patterns, and appearance. Keep seams away from sinks and appliances if possible.

Who should do the measuring?

Either the homeowner or an experienced kitchen design professional. No matter who measures, take time to be thorough and precise.


Accurate measurements are a critical first step in the process of installing new quartz countertops. Investing the time to carefully measure using the right tools will ensure your new counters fit like a glove and function as beautifully as they look. With some patience and attention to detail, you’ll avoid problems down the road.
