Quartz countertops are an increasingly popular option for home kitchens and bathrooms. Unlike natural stone, quartz is an engineered stone made from crushed quartz, resins, and pigments. This allows quartz to be molded into consistent slabs with a wide variety of colors and patterns. When it comes to installing quartz countertops, proper measuring is crucial for a perfect fit. Here is a detailed overview of how quartz countertops are professionally measured.
Measure the Countertop Area
The first step is to carefully measure the countertop area that the quartz slabs will cover. This includes taking precise measurements of the length, width, and any custom angles or cutouts needed for sinks, cooktops, etc. The installer will map out the whole countertop area to determine the total square footage. Common tools used include:
- Measuring tape – For straight lengths and widths. Must account for overhangs.
- Digital laser measure – For longer distances and angles. Extremely precise.
- Squares – For marking 90 degree angles.
- Levels – To ensure surfaces are flat and plumb.
Every measurement is recorded and input into software to create a detailed plan. Sufficient extra length and width is added to allow for adjustments during installation. Any special edge profiles or backsplashes are also accounted for.
Determine Thickness
Quartz slabs come in standard thicknesses of 3/4″, 1 1/4″ and 2 cm. Thicker slabs are more rigid and better for heavily used surfaces like kitchen counters. Thinner slabs can work for bathrooms, walls, or vertical surfaces. The thickness must align with the cabinetry or supports.
Select Slab Size
Quartz slabs are available from manufacturers in set sizes such as:
- 30” x 120”
- 30” x 144”
- 60” x 120”
The installer maximizes use of the slab size to minimize seams. Software helps optimize the layout and identify how many slabs are needed. This reduces waste and cost. Some jobs may need multiple slab sizes.
Allow for Seams and Joints
It is nearly impossible to cover large countertop runs with a single slab. Seams between adjoining slabs are generally required. The measurer plans seams in inconspicuous areas to minimize their appearance. Smaller pieces are often grouped together. Proper supports must exist beneath seams to prevent cracks.
Account for Cutouts
Any cutouts for sinks, cooktops, or other features are precisely measured. Standard cutout dimensions are used for common appliances. Sufficient clearance is included for any faucets, handles, or accessories. The cutouts are aligned to avoid cracks or weak points in the slab.
Map Edges and Profiles
The installer considers the desired edging and profiles for the front, back, and any exposed sides. Standard options include straight polished edges, beveled edges, ogee edges, and bullnose. More complex edge work may require special measurements and templating. Any special routing for joints or backsplashes is also noted.
Create a Template
Once all measurements are complete, the installer creates a cardboard template showing the complete layout. This includes the overall shape, any seams, edges, cutouts, and other details. The template is used to transfer all dimensions to the actual quartz slabs for precision cutting. This helps ensure a perfect fit.
Carefully Inspect Slabs
Prior to fabrication, the selected quartz slabs are closely examined for any cracks, chips, or flaws. Their coloration and patterning is also verified to match what was ordered. Any issues can be addressed before costly cutting. The measurements may need adjustment to account for defects or slight size variations.
Precision Fabrication
Using the template, the quartz fabricator cuts the slabs to the exact measured size using specialized saws and cutters. The cutouts and edging are also formed according to the measurements. CNC machines ensure cutouts fit appliances precisely. Any final hand polishing or engravings are completed.
Double Check Fit Prior to Install
Before permanently installing the quartz countertop, the installer does a dry fit without any adhesive. This verifies that the slabs align properly, seams are tight, and all cutouts fit as intended. Minor adjustments can be made before final installation.
Proper measurement is clearly crucial for a successful quartz countertop installation. Every step must be completed with precision to ensure a perfect custom fit and professional appearance. Following these measurement best practices will lead to stunning quartz countertops that meet your unique needs.
Frequently Asked Questions About Measuring Quartz Countertops
How much overhang should I allow for with quartz countertops?
An overhang of 1 to 1 1/2 inches is standard for quartz countertops. This provides enough space for bar stools or decorative trim. Larger overhangs up to 2 inches can also work but may require additional support.
What tools do I need to measure for quartz counters myself?
A measuring tape, carpenter’s square, and level are essential for DIYers. A digital laser measure can also be useful for greater accuracy on long spans. Make detailed sketches of all measurements.
Should I measure old countertops or cabinets for new quartz counters?
It’s best to measure the cabinet boxes themselves, not existing countertops. This provides the true dimensions the new slabs must fit. Account for new overhangs and edges.
How are rounded corners and special shapes measured?
An experienced installer can create a template to duplicate complex shapes and curves. Specialty router bits can also cut bullnose edges and custom profiles.
Can quartz counters be trimmed onsite if my measurements are off?
It’s best to avoid this through precise measuring. But skilled pros can trim edges slightly with diamond blades. Seams and cutouts, however, cannot be adjusted onsite.
How do I account for sinks and cooktops in quartz measurements?
Consult the manufacturer specs for precise cutout dimensions. Allow a 1/8″ gap around sinks to prevent cracks from settling. Cooktops often require precise cutouts for clamps.
What if my quartz seams don’t align correctly during dry fit?
A fabricator can grind the seam edges slightly to improve alignment. Other options include a small backsplash to cover gaps or strategically placed caulk.
Can I use the same quartz measurements for a backsplash?
Not always. Backsplash pieces are often cut differently to allow for thinner dimensions and proper support. Best to measure and template backsplashes separately.
Conclusion
Measuring for quartz countertops requires precision at every step. Carefully mapping the area, planning seams, accommodating cutouts, and designing edges are all crucial. Using the proper tools, making detailed templates, and double checking fits also ensures success. With accurate measurements, your stunning new quartz countertop installation will perfectly match your space and needs for many years to come.
