Introduction
Installing quartz countertops can transform the look and feel of your kitchen or bathroom. Quartz is an engineered stone made from crushed quartz, resin, and pigments. It is an extremely popular choice for countertops due to its durability, appearance, and ease of maintenance. When it comes to quartz countertop installation, one of the key considerations is how much quartz to purchase. Calculating the right amount ensures you don’t end up with too little or too much. This comprehensive guide will provide useful tips and insights on determining how much quartz countertops you need.
How to Measure for Quartz Countertops
The first step is accurately measuring the countertop area that needs to be covered. Here are some helpful guidelines on how to measure:
Create a Detailed Sketch
Draw a detailed sketch of the countertop layout showing all dimensions. Mark down lengths, widths, corners, edges, cutouts, and overhangs. This helps you determine the total square footage.
Measure in Sections
Divide the countertop into distinct rectangular sections. Measure the length and width of each section. Account for any irregular shapes or angles separately.
Include Overhangs
Standard overhang is 1.5 inches on each exposed edge. Make sure to add overhang measurements when calculating linear feet.
Consider Thickness
Standard quartz thickness is 3 cm (1.2 inches). Some applications may need thicker 2 cm (0.8 inch) pieces. Factor this into total quartz requirements.
Use a Flexible Tape
Use a flexible metal measuring tape for accuracy. Measure to 1/8th of an inch. Double check all measurements.
Add Up the Sections
Add together the square footage of each individual section to derive the total countertop area.
By following these guidelines, you can get highly precise measurements for your quartz countertop installation.
How Much Quartz Do You Need?
Once you have calculated the total square footage, use the following estimates for how much quartz to purchase:
- For a 1.2 inch (3cm) thick quartz countertop, you will need 1.3 pounds per square feet.
- For a 0.8 inch (2cm) thick quartz countertop, you will need 0.875 pounds per square foot.
- We recommend getting 10-15% extra quartz above your measurements to account for cutting waste and edge details.
- For backsplashes, calculate 0.5 pounds per linear foot, with a standard height of 4 inches.
Let’s take an example to understand the math:
- Total countertop square footage: 50 sq. ft.
- Thickness: 1.2 inches (3cm)
- Overhang: 1.5 inch on three sides
- Backsplash: 10 linear feet
- Countertop quartz needed: 50 sq.ft. x 1.3 pounds = 65 pounds
- Add 15% extra for wastage: 65 x 0.15 = 9.75 pounds
- Total quartz for countertop: 65 + 9.75 = 74.75 pounds
- Backsplash quartz needed: 10 linear ft. x 0.5 pounds = 5 pounds
- Total quartz required = 74.75 + 5 = 79.75 pounds
This estimated calculation method gives you a good idea of how much quartz you will need to order. Always get measurements from your quartz supplier as well.
Factors Impacting Quartz Requirements
Here are some important factors that can increase your quartz requirements:
- Complex layouts with multiple seams, edges, and cutouts will lead to more wastage.
- Thicker 2 cm quartz slabs will require more material.
- Large overhangs beyond 1.5 inches will increase pounds per linear foot.
- Choosing patterns like marble or veining can require 5-10% more quartz.
- Separate backsplashes or additional matching pieces will need extra material.
- Having the fabricator make sink or stove cutouts can increase quartz needed.
Knowing these aspects in advance allows you to plan your quartz procurement more precisely.
How to Order Quartz Countertops
Follow these tips for a smooth quartz countertop ordering process:
- Choose a reputable fabricator that provides accurate estimates.
- Give the fabricator your detailed drawings and measurements.
- Select your preferred quartz color, finish, and edge style.
- Specify thickness based on budget and application.
- Request 10-15% excess to avoid any shortages.
- Ask about lead times so you can schedule installation accordingly.
- Clarify delivery, installation, sink/stove cutout, and other service fees.
- Review fabrication and installation warranties.
- Understand payment terms and arrange financing if required.
Doing upfront planning and communicating clearly with your fabricator is the best way to ensure you get high-quality quartz countertops tailored to your needs.
FAQs on How Much Quartz Countertops to Order
How many slabs of quartz will I need?
This depends on slab size, but a 30 sq.ft. slab can cover 25-30 sq.ft. of countertop. Allow for seams and cutouts when estimating number of slabs.
What thickness of quartz should I get?
3cm (1.2 inches) is the most popular as it provides durability at a reasonable cost. 2cm (0.8 inches) can work for some applications but may compromise sturdiness.
What size are quartz slabs?
Standard slab dimensions are about 30 sq.ft. (55 x 144 inches). Jumbo slabs around 35 sq.ft. may also be available.
How much overhang is needed with quartz?
1.5 inches is recommended on exposed edges. Too little overhang won’t support the countertop, while too much can make it prone to cracking.
Does thicker quartz need more overhang?
No, standard 1.5 inch overhang works for both 3cm and 2cm slabs. The overhang measurement does not change with thickness.
How much extra should I get for backsplashes?
Get 20-25% extra quartz above your backsplash measurement. Complex backsplash designs require ordering more material.
Conclusion
Determining the right quartz countertop quantity requires careful planning and measurement. Calculate total square footage based on countertop dimensions and thickness. For backsplashes, measure linear feet. Add 10-15% extra above requirements to account for wastage. Consider special factors like complex layouts, patterns, and cutouts that can increase quartz needed. Order from a reputable fabricator and clearly communicate specifications. Use the guidelines provided in this article to ensure you get the perfect amount of quartz for a successful countertop installation.
