Introduction
Installing a backsplash in your kitchen can completely transform the look and feel of the space. Not only does a backsplash provide an additional layer of protection for your walls against splashes and spills, it also serves as a stylish focal point in the kitchen. When planning a new backsplash installation, it’s important to accurately calculate the square footage of the area you plan to cover in order to purchase the right amount of tile. Calculating the square footage for backsplash is easy to do with just a few simple measurements.
Measuring Wall Space
The first step in determining how much tile you need is accurately measuring the wall space the backsplash will cover. Here’s how to measure for backsplash tile:
Measure Length
Stand facing the wall where the backsplash will be installed and use a tape measure to measure the length of the backsplash area in inches. Start at one end and measure horizontally across to the other end, excluding any areas like windows or appliances that will not be covered with tile. For example, if the total length of the backsplash area is 144 inches, write this measurement down.
Measure Height
Still facing the wall, hold your tape measure vertically and measure the height of the backsplash area from the countertop to the bottom of any upper cabinets. For example, if the height from the countertop to the cabinets is 18 inches, write this down.
Multiply Length x Height
Take the length and height measurements and multiply them together to get the total square inches of coverage area. In our example this would be:
144 inches (length) x 18 inches (height) = 2,592 square inches
This will give you the total coverage area for the backsplash installation.
Determining Square Footage
Once you have the total square inch measurement of your backsplash area, you need to convert this into square feet to determine how much tile is needed.
Here is the quick calculation:
Total sq inches / 144 = Total sq footage
So for our example:
2,592 sq inches / 144 = 18 sq ft
This means you will need enough tile to cover 18 square feet for the backsplash installation.
Factoring in Tile Size
To find out how many tiles you will need, you also need to know the size of the tile you are using. Tile for backsplashes is sold in different sizes like 1-inch mosaics, 3×6 subway tiles, 4×4 tiles, etc.
Look at the packaging of your tile purchase and identify the size. For example, if you are using 3×6 inch subway tile, do the following calculation:
Sq footage x tile width x tile height / Tile size in inches
So using our example above:
18 sq ft x 3 inches x 6 inches / (3×6)
= 72 tiles
This calculates that you will need 72 of the 3×6 inch tiles to cover the 18 sq ft backsplash area.
If using a mosaic tile, make sure the measurement reflects the size of each individual tile piece, not just the sheet size.
Planning for 10% Extra
It’s always smart to purchase at least 10% more tile than your calculations show that you need. This provides wiggle room for any uneven areas, tile cuts, or mistakes in your measurements.
To calculate 10% more tile:
Tiles needed x 1.1 = Tiles to purchase
Continuing our example:
72 tiles x 1.1 = 79 tiles
So for a backsplash using 3×6 inch subway tile that covers 18 sq feet, you should purchase 79 tiles to have a 10% buffer.
Full Calculation Example
Let’s look at a full calculation example from start to finish:
- Backsplash Length: 144 inches
- Backsplash Height: 18 inches
- 144 x 18 = 2,592 sq inches
- 2,592 sq inches / 144 = 18 sq ft
- Tile size: 4×4 inch
- 18 sq ft x 4 inches x 4 inches / 16 sq in = 36 tiles
- Add 10%: 36 x 1.1 = 40 tiles
So for a backsplash measuring 144 inches x 18 inches using 4×4 inch tile, you need to purchase 40 tiles.
Purchasing Materials
Once you’ve calculated the number of tiles needed, here are some other material considerations for purchasing:
- Tile adhesive – Calculate 1/4 in trowel coverage per tile and purchase accordingly
- Grout – Estimate 1/8 lb per sq ft; purchase a shade lighter than your tile
- Tile edging – Measure linear feet needed and add 10%
- Sealer – Ensure it is compatible with your tile material
Be sure to add anything else needed for the installation like backerboard, spacers, grout float, etc. Have all materials on hand before beginning the project.
Hiring a Professional
If you plan to hire a professional installer for your backsplash, they will be able to do all the tile calculations for you after doing measurements. Provide them with the tile choice and size and the installer can determine exactly how much material is required. This takes the guesswork out of purchasing.
Pros can also account for pattern layouts, difficult angles, and skillfully cutting irregular shapes around outlets and fixtures. The right tile contractor will help make your installation look clean, sharp, and professionally done.
Tile Calculator Tools

How to Prepare the Wall for a Backsplash
Installing a backsplash in your kitchen provides visual appeal and an easier-to-clean protective barrier above countertops. With the right tile and some preparation, it can be a great DIY project to tackle. Properly prepping your kitchen wall for a backsplash ensures the tile adheres securely for the long term.
Here are the key steps to prepare walls for backsplash tile:
Clean Thoroughly
The wall must be clear of any debris, grease or oils for the tile to stick properly. Wash the entire backsplash area by scrubbing with soap and water, then rinse clean. Pay extra attention to clean above the stove and sink.
If existing paint or wallpaper needs to be removed, use a stripper and putty knife to clear the area to the bare surface. Remove any remaining adhesive residue using adhesive remover.
Repair and Patch
Inspect the wall and make any necessary repairs before tiling:
- Fill holes, dents and gouges with spackling paste
- Sand rough areas for a smooth finish
- Use caulk to seal joints, gaps and uneven borders
All repairs should be flush with the wall surface so the tile sits evenly. Allow patching materials to dry completely.
Prime Painted Surfaces
If painting the wall first, be sure to apply high-quality primer over the paint before tiling. This helps the adhesive grip properly. Allow the primer coat to dry fully before installing tile.
Install Backerboard
Cement backerboard provides the right backing surface for a backsplash. Measure and cut boards to size using a utility knife. Secure them with backerboard screws placed every 8 inches.
Stagger the seams in opposing directions and leave 1/8th inch between boards. Tape and ‘mud’ seams with tile adhesive to create one unified surface.
Apply Waterproof Membrane
Using a waterproofing membrane as an additional layer of protection helps prevent moisture damage behind the tile. Roll on two coats of membrane, allowing the first to fully dry before adding the second.
Plan Your Pattern
Dry lay a row of tiles across the backsplash area before installing to confirm your desired pattern and placement. This can help expose any potential problems with the layout.
Make adjustments before the actual tiling begins. Use spacers to get the joint spacing correct.
Safety Precautions
Take safety precautions when preparing walls for backsplash:
- Wear protective goggles to avoid eye injuries
- Use a mask when sanding walls or removing adhesives
- Wear gloves when applying primers and sealants
- Follow safety directions for any chemical stripping products
- Handle backerboard carefully – the cut edges can be sharp
Once your walls are prepped, you’ll have a surface that’s ready for tile adhesion and installation success. Take the necessary time upfront to properly prepare for a quality finished project.
Tiling Techniques and Tips for Backsplash Installation
Installing tile as a kitchen backsplash creates a stylish focal point and provides protection for the walls. While tiling may seem straightforward, following the right techniques will help you achieve results that look professionally done. Here are some of the top tips for properly installing backsplash tile:
Prepare the Surface
Be sure to follow all the steps to prep and ready the backsplash area as covered in the previous section. This provides a smooth, clean and dry surface for successful tile adhesion.
Establish Your Starting Point
For the most uniform appearance, start tiling in the center and work outward. Find the midpoint of your focal area and lay the first tile. Dry fit a full row along the center before applying any adhesive to confirm alignments.
Apply Tile Adhesive
Use a notched trowel to spread a layer of thinset adhesive on the wall, applying just enough that you can tile over within 10-15 minutes before it dries. Spread in 3×3 foot sections to work in manageable areas.
Follow Layout Lines
Measure and mark layout lines on all sides of the backsplash area. This keeps tiles aligned, especially helpful when working with rectangular subway tiles. Place the first row of tiles along the bottom line, leaving a 1/8 inch gap between the countertop and tiles.
Use Tile Spacers
Place tile spacers between each tile to maintain even grout line spacing. Spacers create uniform joints and prevent tiles from shifting during installation.
Cut Tiles Accurately
Measure and mark tiles to cut for edges and around outlets or fixtures. Use a wet saw to accurately cut ceramic, porcelain or glass tiles. Score and snap tiles for detailed contour cuts. Use nippers for quick small trims.
Check Levels and Alignment
Periodically place a level across the tiles to confirm the rows are straight. Step back and verify the layout aligns with your starting point and isn’t shifting to one side. Make any necessary adjustments promptly.
Apply Pressure When Setting
After spreading adhesive on the back of each tile, firmly press in place while wiggling slightly to collapse the adhesive ridges. This embeds tiles flatly without uneven glue bumps.
Clean as You Go
Use a damp sponge to frequently wipe away excess adhesive along grout lines before it dries. Working in small sections makes this easier. Avoid smearing adhesive over the tile faces.
Allow Proper Setting Time
Let the tile adhesive cure for at least 24-48 hours before grouting unless the product directions specify otherwise. This prevents tile shifting or grout cracking later on.
Following these professional techniques for properly installing backsplash tile helps ensure your project looks fantastic and the tile bonds durably to the wall surface. Paying attention to details like layout lines, adhesive application, and joint spacing makes achieving success easy.
Selecting Grout Color for a Kitchen Backsplash
An often overlooked but highly important finish step after tiling a backsplash is selecting and applying grout. While its purpose is purely functional to seal the joints between tiles, grout color can significantly impact the overall look and feel of the backsplash design. When choosing a grout color, it’s important to consider the tile color, texture, spacing, lighting, and overall style you want to achieve.
Here are some tips for choosing the right grout color:
Match Grout to Tile
Selecting a grout color that matches the tile is a classic, seamless look. For example, white grout with white subway tiles or beige grout with neutral travertine. Matching also helps hide dirt and is ideal for grout lines 1/8 inch or smaller.
Contrast Grout with Tile
A bold grout color that contrasts with the tile creates definition and outlines each tile. For example, bright white grout with black granite tiles or navy blue grout with white marble. Contrast works best on tiles with larger grout lines of 1/4 inch or wider.
Complement Tile Color
Find a grout shade that ties into one color tone in multicolored tile while contrasting the rest. For example, taupe grout with tiles mixing browns and grays. This helps unify busier tile patterns.
Factor in Tile Texture
Rough tile textures hide grout well, supporting a matching or camouflaging grout color. Smooth tiles put more emphasis on the grout, so use a complementary color. Highly porous tiles benefit from matching as contrasting can stain the tile edge.
Consider Grout Line Width
Narrow grout lines of 1/16 inch or less are harder to clean so match the grout color. Wider grout lines over 1/8 inch make the color more visible, so select a color that enhances the tile.
Account for Lighting
Grout may look different in natural vs. artificial lighting. View tile samples and test grout colors in the lighting conditions where it will be installed. Opt for a slightly lighter shade if unsure.
Think About Overall Style
Rustic or traditional spaces can use matching grout for a cohesive look. Contemporary designs often feature contrasting grout that adds flair. Outdoor kitchens should avoid white grout which stains easily.
Taking the time to shop grout colors and place test patches will ensure you select the right shade for your tile and design style. A thoughtful grout choice can beautifully tie your entire backsplash together!
Cleaning and Caring for a New Backsplash
Once your new backsplash tile is installed and grouted, taking proper care of it from day one will keep it looking as good as the day it went in. Follow this advice for cleaning and maintaining your fresh new backsplash:
Initial Cleaning
Use a soft, damp sponge to gently wash the entire backsplash to remove any haze or remaining grout residue. Avoid harsh scrubbing which can smear grout into the tile pores.
Routine Cleaning
For regular upkeep, use a mild dish soap diluted in warm water. Avoid abrasive cleansers which can damage the tile surface over time. Rinse thoroughly and dry with a soft cloth.
Tougher Messes
For grease splatters or difficult soils, try an all-natural cleaner suitable for your tile material like citrus, vinegar or stone soap. Avoid acidic cleaners on stone.
Do Not Use
Steer clear of the following backsplash cleaners which can etch, scratch or dull the tile: bleach, ammonia, vinegar (on stone), wire brushes, magic erasers, or abrasive scrub pads.
Sealing
Determine if your tile material needs sealing to prevent staining and increase water resistance. Sealers are recommended for grout and porous, unglazed surfaces like natural stone.
Spot Clean
Promptly wipe up any spills, splatters or spots. Soaking or dried-on messes are harder to remove and may require extra cleaning steps. Oily spots may need a degreasing dish soap.
Rinse Thoroughly
Always rinse the entire backsplash fully with clean water after cleaning. Residue left behind from soaps, grease or mineral deposits in hard water can build up over time leading to dull or streaky tile.
Dry Immediately
Use a soft towel or microfiber cloth to dry the backsplash and prevent water spots, especially around faucets and fixtures where dripping occurs.
By regularly following these backsplash cleaning tips, your new tile finish will maintain its beauty and last for many years of use. Avoid waiting until grime builds up to clean or using harsh scrubbing which can deteriorate the grout and tile over time.
Backsplash Maintenance Questions
Q: How often should I clean my backsplash?
A: For routine maintenance, plan to clean the entire backsplash area at least once a week. If the kitchen sees heavier use or frying, daily spot cleaning may be needed.
Q: What’s the best way to clean grout lines?
A: Mix a paste of 3 parts baking soda to 1 part water and apply to grout lines. Allow to sit 5 minutes then scrub with a grout brush before rinsing clean. Vinegar can also help remove soap scum.
