Installing a stylish backsplash in your kitchen or bathroom can dramatically transform the look of the space. But before selecting materials and colors, the first step is properly measuring the area to determine how much tile you need. Accurate measurements ensure you purchase enough backsplash tile to complete the job.

Introduction

A backsplash protects the walls from splatters and spills while adding visual interest to your kitchen or bathroom. Tiling your backsplash allows you to introduce color, texture, and patterns into the design aesthetic. Glass, ceramic, stone, and metal backsplash tiles come in a diverse range of styles.

Measuring for a backsplash tile installation is essential for achieving the best results. Measurements enable you to calculate the square footage of the backsplash area to determine the required tile quantities. Careful planning and measurement also ensure you can center accent tiles and avoid awkward tile cuts.

Below is an overview of how to measure for a backsplash installation, from preparing for measurements to calculating tile requirements.

Steps for Measuring a Backsplash

Clean the Area

Start by clearing counters and removing items on the walls in the backsplash area. Eliminating clutter allows you to access the entire backsplash space and take proper measurements. Clean the backsplash area thoroughly, so measurements aren’t hampered by dirt or debris.

Gather Measuring Tools

You’ll need the following basic tools for measuring a backsplash:

• Tape measure: The tape measure is essential for measuring linear feet. Choose a tape measure that extends to at least 25 feet.
• Measuring stick: A stiff ruler or steel measuring stick ensures straight measurements.
• Pencil and eraser: Mark measurements in pencil then erase marks after installation.
• Chalk line: Snap perpendicular chalk lines on the wall as a guide for laying tiles.
• Spacers: Plastic spacers in different sizes help measure spacing between tiles.
• Laser level: Optional for marking level lines. Extremely helpful for difficult layouts.
• Camera: Photograph the backsplash area to reference install details later.

Measure Length and Height

Start by measuring the length and height of the backsplash area:

• Measure across the bottom of the backsplash area from one end to the other in inches. Record the length.
• Measure from the bottom of the backsplash area to the ceiling or cabinet undersides. Record the height.
• For best results, take measurements at multiple points and average them.

Mark a Level Line

Use a level chalk line to mark a perfectly horizontal line at the bottom of the backsplash area. This gives you a guide to follow when installing the bottom course of tiles.

If the floor or countertop under the backsplash isn’t level, measure up from the high point of the floor rather than assuming the countertop is level.

Look for Obstacles

Note any outlets, switches, windows, or other obstacles in the backsplash area. These will need to be accounted for in tile layouts. Pay attention to:

• Window trim or aprons that overlap the backsplash area
• Moldings, edges, and irregular corners
• Furniture like floating shelves that impede tiling

Plan tile layouts to work around obstacles and achieve a seamless finished look.

Mark the Center

Find the exact center point of the backsplash area vertically and horizontally and mark with a pencil. Use a level to double check center points. This allows you to plan tile layouts symmetrically outward from the center.

Map Tile Patterns

Map out your desired backsplash tile layout to gauge tile requirements. Sketch tile arrangements accounting for focal points, colors, sizes, and textures.

Draw patterns to scale on graph paper using measurements of the backsplash area. Map out full tiles then plan trim and border tiles.

Calculate Square Footage

Use measurements to calculate the total square footage of the backsplash installation area. This determines how much tile is needed.

To calculate square footage:

• Multiply the length times the height of the backsplash area.
• Reduce square footage to account for obstacles like windows and outlets.
• Round up to account for tile cuts and waste.

Allow for an extra 10% of tile over the final square footage for waste and potential breakage. Carefully measure and calculate to buy the right tile quantities the first time.

Measuring for Specific Backsplash Situations

Approaches for measuring backsplash areas may vary based on the location and installation specifics.

Kitchen Backsplashes

In a kitchen, the backsplash typically extends vertically from counter to cabinet and horizontally between countertops, islands, and ranges.

Take measurements following the counter line, subtracting areas covered by appliances. For a full height backsplash, also measure from countertop up to ceiling.

Account for interruptions like sinks, windows, electrical, and vents that impact the tiling area. These Kitchen elements need special treatment when planning tile layouts.

Bathroom Backsplashes

In bathrooms, the vanity backsplash extends vertically from the counter to the mirror or medicine cabinet and horizontally from one vanity edge to the other.

Shower surrounds involve tiling the walls around the shower enclosure perimeter. Measure the height up to the ceiling and length along the bathtub rim or shower base.

Tub surround backsplashes extend vertically from the tub rim to the ceiling and span the length of the tub. Measure the area carefully accounting for plumbing fixtures.

Backsplashes with Outlets

When outlets are in the backsplash area, you can either cut tile around them or remove the outlets temporarily to tile behind.

If cutting tile, measure the outlet box size and height above the counter. Transfer measurements to tiles and carefully cut openings so outlets remain accessible.

Alternatively, have an electrician disconnect and remove outlets so you can completely tile behind. Just be sure to mark outlet locations for reinstall later.

Backsplashes with Windows

Take measurements from sill to ceiling and jamb to jamb to determine the backsplash area around windows.

If the window sill overlaps the backsplash, you can either cut tiles to fit around or remove the sill trim and reinstall after tiling. Just be cautious with windows not to compromise moisture barriers.

Consider framing windows in a border or accent tile that complements the overall design. This creates a finished look when transitioning from backsplash tile to window trim.

Purchasing Materials Based on Measurements

Careful measurements enable you to estimate required materials and associated costs for the tiling project. Avoid purchasing too little tile that leaves you scrambling for more mid-project.

Use square footage calculations to determine quantities of tiles needed. Purchase tile and supplies allowing for overage beyond bare minimums.

Tile Quantity Estimates

Consider the size of your tile to estimate quantities:

• Small mosaics under 2 inches may need 10 or more tiles per square foot.
• Standard 4 inch tiles require 4 tiles per square foot.
• Large format tiles 8 inches or bigger cover just 1 to 1.5 tiles per square foot.

Add 10% over total squares required to account for cuts and waste factor.

Don’t forget to include specialty trim, border, and accent tiles in your order. These extras tiles can tie installations together beautifully.

Mortar and Grout Estimates

In addition to tile, consider:

• Thinset mortar for the tile base – about 60 lb. bags for every 40-50 sq ft.
• Grout – approximately 0.25 lb. per square foot, though more for glass or stone tiles.
• Caulk for sealing gaps and corners.

Again, purchase a bit more than you anticipate needing to avoid running out mid-project.

Tips for Measuring Tricky Backsplash Layouts

Many backsplash installations involve challenging areas or layouts requiring careful pre-planning and measurements. Here are some tips for measuring tricky backsplash tile configurations:

Irregular Shaped Areas

For unusually shaped spaces, take overall length and height measurements then subtract areas that won’t be tiled like windows and appliances.

Break the space into geometric sections to calculate total square footage. Make each section a rectangle or square then add together for the total.

Diagonal Tiles

Laying tiles on a diagonal requires about 15% more tile to account for sawtooth edges.

To estimate diagonal tiling materials, multiply the backsplash square footage by 1.15 as a guideline.

Patterns and Borders

Add up the measurements of any decorative bands or borders you plan to incorporate.

Calculate the linear dimensions of the pattern and multiply by tile dimensions to estimate quantities needed.

Accent Tiles

For periodic accent tiles in the design, sketch layouts and count quantities needed for each location.

Over-order accent tiles to allow for breakage or flaws in accent materials like handmade glass or ceramic.

Double Checking Measurements

Recheck all measurements before purchasing materials to avoid mistakes. It helps to have two sets of eyes to ensure accuracy.

If possible, have an extra person independently measure the backsplash installation area without seeing your measurements. Compare the two sets of measurements and verify any inconsistencies.

Catching discrepancies in advance prevents surprises later when tiling. Taking the time to measure meticulously results in a beautiful, professionally-installed backsplash.

Frequently Asked Questions about Measuring for Backsplashes

Many beginners have additional questions when measuring backsplash areas in preparation for tiling. Here are answers to some frequently asked questions:

How do I measure for a kitchen backsplash around appliances?

In kitchens, measure the backsplash area in separate sections from counter to cabinets. Take measurements following the counter line, subtracting areas covered by appliances, range hoods, sinks, etc. Account for these interruptions when planning tile layouts.

Should I include windows in my backsplash area?

Generally, only measure and tile the backsplash surface under and around windows, not over them. Unless you plan to remove window trim or sills to integrate windows into the backsplash design, exclude window surface area from measurements.

What order should I measure and buy materials?

It’s best to complete all measuring and finalize tile patterns before purchasing. Measure first, then use those calculations to order the necessary tile quantities, adhesive, grout, trim, and tools.

How do I calculate quantities for mosaics or small backsplash tiles?

For mosaics under 2 inches, allow for up to 10 tiles per square foot or more for irregular stone mosaics. Carefully calculating the quantities needed for small tiles ensures you don’t run out near the end.

Why is it important to overestimate how much tile I need?

Adding a 10% overage protects you from running short on tile mid-project. It’s much easier to return extra tiles than to find more matching supplies after assuming you have just enough.

Conclusion

A properly measured backsplash area allows you to purchase the precise quantities of tile and supplies to complete the installation. Preparation and careful measurement also enable you to perfectly design the backsplash around any special layout considerations.

Follow these tips for measuring backsplash spaces:

• Clean and clear the area of obstructions before measuring
• Assemble all needed measuring tools and supplies for the job
• Record key length and height measurements across the entire area
• Look for any obstacles like outlets that impact tile layout
• Use level lines as guides for straight layouts
• Sketch desired tile patterns based on measurements
• Calculate the total square footage and add 10% as buffer
• Double check all measurements before purchasing tile and materials

With an accurately measured backsplash installation space, you can feel confident purchasing enough tile for the project. Just be sure to leave an extra 10% margin in material quantities to account for cuts and waste.

Careful planning and precise measuring will ensure your beautiful new backsplash transforms the room as desired without any last-minute surprises.
