How Thick is Backsplash Tile?

Backsplash tile can come in a variety of thicknesses to suit different design needs and installation requirements. When selecting backsplash tiles, thickness is an important factor to consider for both functionality and aesthetics. This guide will examine the standard thicknesses available for backsplash tiles and what you need to know when choosing the right thickness for your kitchen or bathroom.

What is Backsplash Tile?

A backsplash is a section of tile or other material installed on the wall behind a countertop, most commonly behind a kitchen sink or stove. Backsplashes serve both practical and decorative purposes.

On a functional level, backsplashes protect the wall from water damage, grease, food splashes and other potential stains. They also make a kitchen’s walls easier to clean. From a design standpoint, backsplashes provide an opportunity to add visual interest, color and texture to complement a room’s decor.

Tiles are one of the most popular backsplash materials due to their durability, easy maintenance and variety of colors, textures, shapes and sizes available. Ceramic, porcelain, glass, metal and natural stone tiles are commonly used for backsplashes.

Standard Backsplash Tile Thicknesses

Backsplash tiles are available in a range of thicknesses from 1/4 inch to 1 inch thick. The most common standard thicknesses are:

  • 1/4 inch (5mm) – The thinnest tiles suitable for backsplashes. Often used for mosaics.
  • 3/8 inch (10mm) – A mid-range thickness commonly used for ceramic and porcelain backsplash tiles.
  • 1/2 inch (12mm) – A standard thickness for ceramic, porcelain and natural stone backsplash tiles.
  • 3/4 inch (20mm) – A thicker tile typically used for heavier stone backsplashes like marble, granite or slate.
  • 1 inch (25mm) – The thickest backsplash tiles, usually natural stone or ledgestone.

These are the standard thicknesses, but it’s not uncommon to find backsplash tiles in non-standard thicknesses as well. For example, glass backsplash tiles can range anywhere from 1/8 inch to 1/2 inch thick.

Factors to Consider When Choosing Tile Thickness

When deciding which thickness of tile is right for your backsplash, there are several things to take into account:

Weight and Durability

In general, thinner tiles are lighter in weight while thicker tiles are heavier and more durable. Thinner backsplash materials like glass and mosaics tiles can break more easily from impacts. Heavier stone backsplash tiles can better withstand cracks, chips and damage over time.


Thicker tiles tend to remain flatter and prevent warping or bending. Thinner tiles can sometimes warp or pop off the wall over time if not properly installed.

Layout Patterns

Thicker tiles with wide grout lines suit many backsplash patterns like herringbone and geometric layouts. Mosaics and stacked patterns work well with thinner tile.

Tile Material

Natural stone tiles are often thicker for durability, while ceramic, porcelain and glass backsplash tiles are commonly thinner. Consider the typical thickness for your material.

Grout Lines

Thicker tiles allow for wider grout lines which can add more visual interest. Thinner tiles work better with narrow grout lines and a seamless look.


In general, thinner backsplash tiles tend to be less expensive than thicker tile. Thicker and heavier tiles require more materials, weight and shipping costs.


Thicker tiles may require specialized installation materials like a mortar bed and back-buttering each tile. Thinner lightweight tiles can be applied directly to cement board in most cases.

Thickness Recommendations by Tile Material

Here are some general guidelines on choosing appropriate backsplash tile thicknesses based on tile material:

Ceramic & Porcelain

Ceramic and porcelain backsplash tiles are commonly available in 1/4 inch to 3/4 inch thicknesses. The most popular options are 3/8 inch and 1/2 inch. Avoid extremely thin or thick ceramic/porcelain backsplashes.


Glass backsplash tiles are available from 1/8 inch to 1/2 inch thick. 1/4 inch glass offers durability without the weight of thicker glass. Extremely thin glass can be prone to breaking.


Mosaic sheets range from 1/4 inch to 3/8 inch in thickness. Individual mosaic tiles are typically 1/4 inch thick. The small size suits thinner and lighter material.

Marble & Granite

For marble and granite backsplashes, 3/4 inch thickness provides durability and prevents cracking or warping. 1/2 inch stone tiles can also work with proper installation and sealant.

Slate & Ledgestone

Slate and ledgestone backsplash tiles are commonly 3/4 inch to 1 inch thick, with 1 inch being the most heavy-duty option for a natural stone look.


Metal backsplash tiles like tin, copper or stainless steel are usually available in 1/16 to 1/8 inch thicknesses. Avoid thicker metal that could dent or puncture easily.

How is Tile Thickness Measured?

Backsplash tile thickness refers to the height or depth of an individual tile from front face to back. It does not include any backing material or mesh attached to the tiles.

Tile thickness is measured in inches or millimeters. Standard U.S. measurements are in inches like 1/4 inch or 1/2 inch. Metric thicknesses are in mm, such as 5mm or 10mm.

When purchasing tile, the packaging or catalog listing will always note the tile thickness. If it is not clearly specified, be sure to confirm before making a purchase.

Does Tile Thickness Affect Installation?

The thickness of your backsplash tile does impact the installation process. Thinner, lighter tiles can often be applied directly onto cement board or drywall. Heavier, thicker tiles may require:

  • Mortar Bed: A mortar bed of thin-set is applied to the wall and allowed to cure before installing the tile. This provides a very secure base.
  • Back-Buttering: Thicker tiles should have thin-set mortar applied to the back of each individual tile in addition to the wall surface.
  • Specialty Adhesive: Heavy stone backsplashes may require a specialty adhesive formulated for weight and durability.

Consult your tile installer on the best products and methods for your backsplash tile thickness and material. Careful prep and proper installation will prevent tiles from cracking or coming loose over time.

What Grout Width for Different Tile Thicknesses?

Grout width ranges are recommended based on tile thickness:

  • 1/4 inch to 3/8 inch tiles: 1/8 inch grout lines
  • 1/2 inch tiles: 1/8 inch to 3/16 inch grout lines
  • 3/4 inch tiles: 3/16 inch to 1/4 inch grout lines
  • 1 inch tiles: 1/4 inch grout lines or wider

In general, grout lines should be wider as tile thickness increases. Wider grout suits thicker stone tiles, while thin grout works for thinner mosaic sheets. The proportions of grout to tile impact the visual effect.

Test out different grout width options when installing samples to choose the best proportions. Take lighting into account, as wider grout lines tend to look darker and more dramatic. Your tile installer can advise on optimal grout widths.

Can You Mix Thick and Thin Tiles?

It is possible to incorporate tiles of different thicknesses in one backsplash design, though this is typically not recommended. Using tiles of varying thickness can make it more challenging to achieve a flush installation with even grout lines. The thinner tiles may require a mortar bed or other special prep to match the thickness of thicker tiles.

For best results, choose tiles of consistent thickness for a given backsplash. Work with your tile supplier and installer to verify that all products selected are compatible and can be properly installed together. Careful hand-cutting and precision is required when combining tile thicknesses.

If you do opt to mix thicknesses, keep the variations minimal – such as combining 1/2 inch and 3/8 inch tiles rather than 1/4 inch with 1 inch. Limit the thinner tiles to mosaic accents or borders rather than mixing throughout the whole backsplash.

Typical Thickness by Tile Shape

Shape and size can impact suitable tile thickness as well. Here are some typical backsplash thicknesses based on tile shape:

  • Subway Tile: 1/4 inch or 3/8 inch
  • Penny Tile: 1/4 inch or 3/8 inch
  • Hexagon Tile: 1/4 inch or 3/8 inch
  • Diamond Tile: 1/4 inch
  • Large Format Tile: 1/2 inch or 3/4 inch
  • Mosaics: 1/4 inch mesh sheets or individual tiles
  • Ledgestone: 1 inch
  • Marble Bricks: 3/4 inch or 1 inch

In general, smaller tiles and mosaics are thinner, while larger tiles and natural stones are thicker. Consider how tile size and thickness work together from both a functional and aesthetic standpoint.

Does Thicker Tile Make a More Durable Backsplash?

In most cases, thicker backsplash tile does provide more durability and longevity than thin tile. There are a few factors that contribute to this:

  • Reduced risk of cracking or chipping: Thicker tiles are less prone to cracking or sustaining fractures and damage from impacts.
  • Support weight better: Heavier natural stone, ledgestone, and marble backsplash materials are cut thicker to support the weight without sagging or detaching from the wall.
  • Resist warping: Thicker tiles maintain their shape and lie flat against the wall. Thinner tiles can sometimes warp or curl at the edges over time when improperly installed.
  • More suitable for messy areas: Thicker tile can better withstand cooking splatters, grease, daily wear-and-tear and frequent cleaning near stoves and sinks.

However, thinner porcelain, ceramic and glass backsplash tiles can also provide a very durable and low-maintenance option when properly sealed and installed. Take the material, layout, location and installation method into account when evaluating durability – thickness is just one factor.

Is There a Minimum Thickness for Backsplash Tiles?

There isn’t a universal minimum thickness standard, as options range from extremely thin 1/8 inch mosaic tiles to thick 1 inch ledger tiles.

However, many sources recommend avoiding tiles thinner than 1/4 inch for backsplash installations. Extremely thin tiles under 1/4 inch are at higher risk of cracking or coming loose over time. They require very precise installation and flat walls for the best results.

3/8 inch is a common minimum thickness used for ceramics, porcelain and glass backsplash tiles. This provides ample durability without weighing down the material.

For stone backsplashes, a 3/4 inch minimum thickness is best to support the weight of natural materials like marble or granite. This prevents cracking, chipping and other damage.

Consult your designer and tile installer for their recommended minimums based on your specific backsplash design, tile choices, wall surface and installation methods. Carefully follow all manufacturer instructions for tile thickness requirements.

Is There a Maximum Backsplash Tile Thickness?

There is no definitive maximum thickness standard for backsplash tiles. Ledgestone and other textured stone backsplash tiles can range up to 1 1/2 inches thick in some cases. These require the right wall support and installation methods to handle the weight.

However, backsplash tiles exceeding 1 inch thickness are not very common. Natural stone tiles thicker than 1 inch can become extremely heavy and difficult to work with on a vertical surface. The average range for most backsplash installations is between 1/4 inch and 3/4 inch thick.

One inch is a common maximum used for robust natural stone backsplash installations. Take the material, layout, wall surface and total square footage into account when determining if thicker tile over 1 inch is suitable.

Always follow the tile manufacturer’s instructions and get your installer’s assessment of the maximum thickness that can be supported for your specific backsplash project.

Choosing the Best Thickness for Your Backsplash Tiles

Consider the following when deciding on backsplash tile thickness:

  • Tile material – Recommended thicknesses vary by material type
  • Location – Backsplashes around stoves or sinks benefit from more durable thicker tile
  • Grout lines – Wider grout suits thicker tiles, narrow grout works with thin tiles
  • Installation – Thicker tiles may require special prep like a mortar bed
  • Pattern – Smaller mosaic patterns suit thin tile, ledgestone layouts use thicker tile
  • Weight – Very thick natural stone will be heavy
  • Durability – Thicker tile resists cracking and damage but can weigh down a wall
  • Cost – Thicker tile uses more material and tends to increase cost

Carefully weigh the pros and cons of tile thickness for your individual backsplash installation. Don’t assume thicker is always better – factor in your design goals, tile choices, budget and the installers recommendations.

Typical Thickness Ranges By Material

To recap typical tile thickness ranges by backsplash material:

  • Ceramic & Porcelain: 1/4 inch to 3/4 inch
  • Glass Tile: 1/8 inch to 1/2 inch
  • Mosaic Tile: 1/4 inch sheets or individual tiles
  • Marble & Granite: 1/2 inch to 3/4 inch
  • Slate & Ledgerstone: 3/4 inch to 1 inch
  • Metal Tile: 1/16 inch to 1/8 inch

Use these as general guidelines and always defer to the manufacturer’s instructions for your specific product. Consult your designer or tile installer regarding recommended thicknesses for your project.

Frequently Asked Questions About Backsplash Tile Thickness

What is the most common backsplash tile thickness?

The most popular backsplash tile thickness is 1/2 inch. This mid-range thickness suits many materials like ceramic, porcelain and natural stone. It offers durability without being overly heavy.

What thickness of tile is best for kitchen backsplash?

For kitchen backsplashes, a 3/8 or 1/2 inch tile thickness works well. This thickness range is durable to withstand splashes and stains yet not too heavy. Glass, ceramic, marble, and porcelain kitchen backsplash tiles are commonly cut to 3/8 or 1/2 inch thick.

Can you use 12×24 tiles for a backsplash?

Yes, 12×24 inch tiles with a 1/2 inch thickness are suitable for backsplash installation. Large format 12×24 tiles create a seamless minimalist look. The 1/2 inch thickness supports the tile while preventing them from feeling too heavy on a vertical backsplash surface.

What is the most durable backsplash tile thickness?

For maximum backsplash durability, 3/4 inch or 1 inch stone tiles provide the most impact-resistant, long-lasting option. However, thickness is just one factor – the tile material, quality, sealants and installation method also impact durability. Well-installed 1/2 inch porcelain or ceramic tile can also be very durable.

Is 3/8 or 1/2 inch tile better for backsplash?

For most backsplash installations, 1/2 inch tile thickness provides a good balance of durability without weighing down the wall. However, 3/8 inch tiles are almost as durable, more lightweight and often more affordable. Either 3/8 inch or 1/2 inch tiles (10mm vs 12mm) are good choices for common backsplash materials.

Can I use 1/4 inch tiles for a backsplash?

1/4 inch tiles can be used for backsplashes but may not be the most durable long-term option. Ensure 1/4 inch tiles are rated for wall use. Use extra care during installation to prevent cracking or loosening over time. Mini mosaic tiles are commonly 1/4 inch and suitable when applied properly.

What thickness of tile should I avoid?

Avoid tiles thinner than 1/4 inch, which increase the risk of cracking and damage over time. Be cautious of extremely thick and heavy stone tiles over 1 inch thick, which can be difficult to properly install on walls and may weigh down the surface.


Backsplash tile comes in a range of thicknesses from 1/4 inch thin-set mosaics to 1 inch natural stone slabs. When choosing backsplash tile thickness, take into account the material, application, installation requirements and visual goals. Standard thicknesses between 1/4 inch to 3/4 inch are suitable for most backsplash installations. Follow manufacturer guidelines and talk to installers to determine the best thickness for your specific backsplash project. With the right tile thickness chosen during the design phase, you can create a functional, durable and beautiful backsplash focal point.
