If you’re looking for a new countertop material, shopping for a new quartz countertop may be at the top of your list. But have you considered every important aspect when choosing the quartz countertop that you want aside from its color, design, and size?

One key factor of a quartz countertop’s dimensions that should never be overlooked is its thickness. You might wonder if the quartz thickness really matters, and the answer is yes. Quartz countertop thickness depends on the purpose that it’ll serve in your kitchen. In this case, when choosing the best grade of thickness, you’ll rely on how you intend to use your countertop. There are three grades of quartz worktop thickness:

  • ultra-thin (1-1.2cm)
  • thin (2cm)
  • thick and heavy (3cm)

So how thick should quartz countertops be? Here are the ideal sizes based on how you want to install them in your home and the aesthetics that you prefer.

Standard Thickness Options for Quartz Countertops

1 CM Quartz Countertops

Cost per square foot: $45 – $70

Quartz countertops that are 1cm thick, also known as “thin” or “narrow” slabs, are gaining popularity for their sleek and contemporary look. With a thickness of about 0.39 inches, thin quartz countertops offer a lightweight and cost-effective option for homeowners.

They’re especially favorable for vertical applications like backsplashes and wall cladding due to their reduced weight and ease of installation. However, it’s essential to consider that thinner countertops like these may require additional support and care during handling and installation.

While their affordability and stylish appearance appeal to some, their durability and resistance to impact may be comparatively lower than thicker options.

2 CM Quartz Countertops

Cost per square foot: $60 – $100

Quartz countertops that are 2 cm or approximately 0.79 inches thick, strike a balance between aesthetics and functionality. This is the right quartz countertop thickness for many kitchens and bathrooms due to their versatility and reasonable price.

This counter thickness provides ample strength and support for most applications without requiring extra reinforcement during installation. Homeowners often opt for 2 cm thickness for countertops that combine elegance with practicality.

Whether used in kitchens, bathrooms, or other surfaces, 2 cm quartz countertops offer an excellent blend of style, durability, and value for money.

3 CM Quartz Countertops

Cost per square foot: $75 – $150

Quartz countertops that are 3cm or approximately 1.18 inches thick are considered the standard and most widely used option in residential and commercial settings. Their robustness and substantial feel make them an ideal choice over thinner slabs for kitchen countertops, where durability and long-lasting performance are crucial.

Countertops with 3 cm thickness also allow for various edge profiles, adding to the overall aesthetics of the countertop. While they may come with a higher price tag compared to thinner options, 3 cm quartz countertops offer superior strength, resilience to impact, and minimal need for additional support during installation. They’re a timeless choice that ensures both beauty and functionality in any space.

Factors Influencing Quartz Countertop Thickness Choice

When selecting the perfect quartz countertop for your home, one of the critical decisions you’ll face is choosing the right thickness. Several factors come into play when making this choice, each influencing the final appearance, functionality, and performance of your countertops. Let’s explore the key considerations that can guide you toward the ideal quartz countertop thickness.

1. Style and Aesthetics

Both style and aesthetics play a crucial role in the decision-making process.

Thicker countertops, such as 3 cm slabs, often exude a more luxurious and substantial look. This can be ideal for traditional or grander kitchen designs. On the other hand, 1 cm and 2 cm slabs are favored for modern and minimalist aesthetics, providing a sleek and seamless appearance.

Homeowners and designers should consider the overall theme and ambiance they want to achieve in the space to determine the most suitable thickness. It should complement the design elements and architectural style.

2. Durability and Longevity

The thickness of a quartz countertop can directly influence its durability and longevity. Thicker slabs are usually superior in terms of resistance to impact, chipping, and cracking, making them suitable for high-traffic areas and heavy usage. Here’s an average estimation of the longevity of different quartz countertop thicknesses:

  • 1 cm Quartz Countertops: Approximately 10 to 15 years
  • 2 cm Quartz Countertops: Approximately 15 to 20 years
  • 3 cm Quartz Countertops: Approximately 20 to 25+ years

While these estimates vary based on maintenance, usage, and specific conditions, opting for a thicker quartz countertop can contribute to its overall lifespan and ensure it withstands the demands of daily life with ease.

3. Application and Usage

The intended application and usage of the quartz countertop play a vital role in determining the appropriate thickness.

For instance, in a kitchen where countertop surfaces are exposed to constant chopping, heat, and spills, a thicker 3 cm slab provides better protection and longevity. Additionally, larger kitchen islands or areas with heavy appliances may require the extra support and strength that a 3 cm countertop offers.

On the other hand, 1 cm or 2 cm slabs might be well-suited for bathroom vanities, backsplashes, or wall cladding, where their lighter weight and flexibility can be advantageous.

Assessing the specific requirements of your project and the anticipated usage will help you select the most suitable thickness for your quartz countertops.

Pros and Cons of Different Thicknesses

1. CM Thickness: Advantages and Limitations

With a slim profile of just 1 centimeter, 1 cm quartz countertops offer a contemporary and minimalist look that appeals to modern design sensibilities. While they may be thinner than other options, they come with both advantages and limitations to consider.


  • Sleek Aesthetics: 1 cm quartz countertops provide a sleek and elegant appearance, adding a touch of sophistication to any space.
  • Cost-Effectiveness: Due to their reduced material usage, 1 cm slabs are often more affordable than their thicker counterparts, making them an economical choice.
  • Versatile Applications: The thin profile makes 1 cm quartz suitable for vertical applications like backsplashes, wall cladding, and fireplace surrounds, offering design continuity throughout the room.


  • Fragility: One of the main limitations of 1 cm quartz countertops is their reduced thickness. These are more susceptible to chipping or breakage.
  • Additional Support Required: In horizontal applications, such as kitchen countertops, 1 cm quartz may require additional support to prevent flexing and ensure durability.
  • Limited Edge Profiles: The thinner profile restricts the availability of certain edge profiles, potentially limiting design options.

While 1 cm quartz countertops bring a contemporary and cost-effective solution to modern spaces, they require careful consideration for specific applications due to their reduced thickness and potential fragility.

2. CM Thickness: Pros and Cons

Offering a balance between aesthetics and practicality, 2 cm quartz countertops are a popular choice for various residential and commercial projects. Let’s explore their advantages and limitations.


  • Sturdier Profile: The 2 cm thickness provides better structural support compared to 1 cm, making it suitable for horizontal applications without requiring additional reinforcement.
  • Wider Edge Profiles: With a slightly thicker profile, 2 cm quartz allows for a broader range of edge profiles, adding customization options to match your desired style.
  • Versatile Use: 2 cm quartz can be used in both horizontal and vertical applications, offering more design flexibility throughout your space.


  • Price: While more affordable than 3 cm options, 2 cm quartz may still be costlier than 1 cm, impacting the overall budget for your project.
  • Edge Seam Visibility: Depending on the edge profile chosen, seams on 2 cm countertops may be more visible than those on thicker surfaces.
  • Reduced Impact Resistance: Compared to 3 cm quartz, 2 cm may have slightly reduced impact resistance due to its thinner profile.

Quartz countertops that are 2cm thick strike a balance between style and functionality, offering design versatility and sturdiness for a variety of applications.
