Introduction

Installing a tile backsplash in your kitchen or bathroom can really enhance the look and feel of the space. However, before you start tiling, it’s important to accurately calculate the square footage of the area you’ll be tiling. This will determine how much tile and grout you need to purchase. Figuring out square footage for a backsplash is easy once you understand the basic method. We’ll walk you through the complete process step-by-step.

Measuring Wall Space

The first step is to measure the wall space where you’ll be installing the backsplash. Here’s how to do it:

Sketch the Layout

Grab a pen and paper and sketch the layout of the backsplash area. Mark down the dimensions of any windows, cabinets, appliances, etc. that you’ll be working around. This helps give you a visual reference.

Measure Length & Height

Using a tape measure, measure the length and height of the backsplash area in inches. For the height, measure from the countertop to where you want the backsplash to end. Often backsplashes end where wall cabinets begin.

Write down each measurement. You’ll need these numbers to calculate the square footage.

Account for Irregularities

If the backsplash area isn’t a perfect rectangle, you’ll need to take separate measurements. Measure any recesses, protrusions, angles, or uneven sections. Sketch these irregularities on your layout.

Double Check Accuracy

Triple check all your measurements to verify accuracy. Even small measurement mistakes can lead to ordering the wrong tile quantities. It’s better to spend extra time measuring than to end up short on materials.

Calculating Square Footage

Now that you have precise linear measurements, it’s time to calculate the total square footage. Here are two simple methods:

Length x Height Method

Multiply the length by the height to get total square feet:

Length of backsplash area in inches
Height of backsplash area in inches
Length x Height / 144 (to convert to square feet)

If there are multiple sections, calculate each section separately then add them together.

Tile Method

Determine the square inch size of your tile, then divide by 144 to get square feet per tile. Next, estimate how many full tiles will fit length and height. Multiply length tiles by height tiles to get the total number of tiles. Finally, multiply the total number of tiles by the square feet per tile.

For example:

4 x 4 inch tile size
4″ x 4″ = 16 square inches
16 sq in / 144 = 0.11 sq ft per tile
10 full tiles fit length
5 full tiles fit height
10 tiles x 5 tiles = 50 total tiles
50 tiles x 0.11 sq ft per tile = 5.5 sq ft

This tile method accounts for leftover partial tiles and gives you an accurate total square footage amount.

Factoring in Standard Deductions

Once you’ve calculated the total square footage, there are some standard deductions you’ll want to account for:

10% Overage Deduction

It’s smart to purchase 10% more tile than calculated square footage. This covers tile cuts and waste. So deduct 10% from total square feet to get your purchase amount.

Grout Deduction

Grout lines take up space between tiles. For standard 1/8″ grout, deduct 8% from total square feet. Adjust deduction for wider grout.

Pattern Deduction

If laying tiles in a brick pattern, deduct 5% for offset. Other patterns may not need deduction.

Factor in these deductions so you don’t end up short on materials!

Dealing With Irregular Backsplash Shapes

For backsplashes that aren’t straight rectangles, you’ll need to break the area into smaller rectangles, triangles, or other shapes when calculating square footage. Here are some examples:

Kitchen Peninsula

Measure straight sections separately from angled peninsula area. Calculate square feet of each then add together.

Window Recess

Take separate measurements for the recess then subtract it from the total.

Trapezoid Shape

Divide into rectangle and triangle sections. Calculate each then add together.

Accent Tile Stripes

Deduct vertical accent tile strips when estimating number of field tiles needed.

Measure and calculate irregular sections piece-by-piece to get an accurate total square footage amount.

Saving Your Measurements

Once you’ve completed all the measurements and calculations, be sure to save your notes! Here are some tips:

Take photos of measurements with your phone
Draw up a proper scale drawing
Input calculations into a spreadsheet
Save measurements in your project notebook

Having all the info documented will make it easy to reference when you go to purchase materials. You’ll also have it handy down the road if you ever need to retile the backsplash.

Purchasing Materials for Project

Now comes the fun part – shopping for tiles! Keep the following material purchasing tips in mind:

Order Extra Tile

Always order 10-15% more tile than your square footage calculations. Extras come in handy for any damaged tiles or future repairs.

Calculate Adhesive Needed

Check manufacturer specs for thinset coverage rate. Divide square footage by coverage to get quantity needed.

Estimate Grout Amount

Common sanded grout coverage is 25-30 sq ft per pound. Use this to estimate how many pounds you’ll require.

Get Extras Tools/Supplies

Stock up on extras like grout sealer, tile spacers, tile cutter blades, etc. Shopping in advance saves time and hassle.

Organize Delivery Schedule

Have all materials delivered 2-3 days before start date so everything is ready to go on day one.

Careful planning and ordering of materials helps ensure your tiling project goes smoothly from start to finish!

Step-by-Step Installation Process

Once materials are purchased, it’s go time! Follow this process for proper backsplash installation:

1. Prepare the Surface

Clean surface thoroughly and remove any old backsplash
Evaluate surface flatness and make repairs if needed
Mark appropriate height and create a lower ledge if desired

2. Apply Thinset Adhesive

Spread thinset evenly using proper trowel size
Use notched edge trowel at 45 degree angle to create ridges
Only spread thinset over amount of space you can tile in 30 minutes

3. Set & Space the Tiles

Starting at a focal point, press tiles firmly into thinset
Use plastic tile spacers for consistent grout line widths
Be sure tiles are aligned and lay flat without gaps or lippage

4. Cut Accent & Border Tiles

Measure and mark tiles needing cut with pencil
Use wet saw or tile cutter to cut border and accent tiles
Blend cuts into design and set tile

5. Grout the Tile

Let thinset cure fully per manufacturer instructions before grouting
Apply grout with grout float, pressing into joints between tiles
Wipe away excess grout with damp sponge
Clean haze from tile faces with soft cloth

6. Seal the Grout

Let grout cure fully before applying sealer
Apply grout sealer with thin foam brush
Wipe away excess sealer from tile faces
Follow manufacturer recommendations for drying time

Following proper installation techniques results in a stunning finished backsplash!

Frequently Asked Questions
