How Thick Should Quartz Backsplash Be?

Installing a quartz backsplash can add style and functionality to your kitchen. Quartz is an engineered stone made from crushed quartz bonded with resin. It’s an attractive, low-maintenance material that resists scratches, stains, and heat. When selecting a quartz backsplash, one key consideration is choosing the right thickness.

What Are the Standard Thicknesses for Quartz Backsplashes?

Quartz backsplashes are commonly available in 3/8 inch, 1/2 inch, and 3/4 inch thicknesses. Here’s an overview of each:

3/8 Inch

  • This is the thinnest option for a quartz backsplash.
  • At 3/8 inch, it provides a sleek, minimalist look on the wall.
  • Best for simple backsplash designs without intricate edges or cutouts.
  • Can be prone to cracking or chipping if not installed carefully.

1/2 Inch

  • The most popular thickness for quartz backsplashes.
  • Provides a good balance of aesthetics and durability.
  • Can accommodate more complex backsplash designs.
  • Less likely to crack or chip than a 3/8 inch option.

3/4 Inch

  • The thickest option for a sturdy, substantial feel.
  • Works well for designs with irregular edges or a stone-like look.
  • Very durable and can withstand heavy use over time.
  • Increased weight requires strong installation and wall support.

What Are the Factors to Consider When Choosing Thickness?

When selecting a quartz backsplash thickness, here are some important considerations:


  • A thinner 3/8 inch backsplash has a streamlined, modern look.
  • A thicker 3/4 inch backsplash creates a bold, stone-like aesthetic.

Complexity of Design

  • Simple backsplash shapes suit a thinner 3/8 inch thickness.
  • Intricate edges and cutouts need a 1/2 inch or 3/4 inch thickness to avoid cracks.


  • 3/8 inch backsplashes are the most affordable option.
  • 3/4 inch backsplashes have a higher material cost.

Ease of Installation

  • Thinner backsplashes can install directly onto drywall.
  • Heavier 3/4 inch backsplashes may require additional supports.

Durability Needs

  • Bathrooms and busy kitchens benefit from a thicker 1/2 inch or 3/4 inch quartz backsplash.
  • A 3/8 inch option works for protected, low-traffic areas.

Contrast With Countertops

  • Matching the backsplash thickness to countertops creates visual continuity.
  • Varying the thickness adds an appealing contrast.

How Thick Should a Quartz Backsplash Be Behind a Stove?

For heavy-use areas like behind a stove, a thicker quartz backsplash is the best choice. A 1/2 inch or 3/4 inch thickness stands up to heat and the busy activity of cooking:

  • It resists cracking or chipping when accidentally bumped by pots and pans.
  • The heavier material won’t shift out of place over time.
  • Greater thickness provides extra durability to withstand high temperatures from the stove.
  • Minimal grout lines make a thicker backsplash easier to keep clean behind a stove.

How Thick Should a Full-Height Quartz Backsplash Be?

Full-height backsplashes that extend from countertop to ceiling have become a popular trend. For this application, a thickness of 1/2 inch is typically recommended:

  • At 1/2 inch, the material is still lightweight enough for easier installation on a full wall.
  • It allows for a seamless, streamlined look from counter to ceiling.
  • Durability is excellent at 1/2 inch for a high-impact, full-height backsplash area.
  • It provides sufficient strength and structure for the taller backsplash area.

If you desire a heavy, stone-like aesthetic, a 3/4 inch full-height backsplash is also an option. Additional wall supports may be needed for the increased weight.

What’s the Best Thickness for an Outdoor Kitchen Quartz Backsplash?

In outdoor kitchens, it’s smart to opt for a thicker 3/4 inch quartz backsplash:

  • The heavier material withstands temperature fluctuations and UV rays.
  • It resists damage from bumps or accidents when cooking outdoors.
  • The thicker profile mimics natural stone and suits an outdoor aesthetic.
  • Excellent durability provides peace of mind in an outdoor environment.

What About Thickness for a Quartz Backsplash With Shelves or Cutouts?

If your backsplash design includes shelves, floating ledges, or intricate cutout patterns, a 1/2 inch or 3/4 inch thickness becomes important:

  • The added thickness provides needed structure around cutouts or openings.
  • It prevents cracking, chipping, or accidents with accessories installed into the backsplash.
  • A sturdier 1/2 inch or 3/4 inch backsplash can securely hold heavier shelves or ledges.
  • Increased durability suits high-traffic areas around floating shelves.


When choosing a quartz backsplash thickness, assess your budget, design plans, and durability needs. While a 3/8 inch backsplash provides a minimalist look, a 1/2 inch to 3/4 inch thickness is recommended for resilience behind stoves, on full backsplashes, in outdoor kitchens, or when incorporating backsplash accessories. Considering factors like aesthetics, complexity, and use can help determine the ideal thickness for your space. With its stylish durability, a well-chosen quartz backsplash adds function and elegance to the heart of your home.
