Installing a backsplash in your kitchen can really transform the look and feel of the space. However, before you start tiling, it’s important to calculate how much backsplash tile you’ll need to purchase. With some simple measurements and math, you can determine the square footage of your backsplash area and estimate the amount of tile you’ll need.
Measure the Backsplash Area
The first step is to measure the area you’ll be tiling. Make sure to measure only the backsplash surface, not countertops or walls.
- Measure the length and height of the backsplash area. For example, if your backsplash is 4 feet high and 10 feet long, you have 40 square feet of backsplash space.
- If you have an irregular shaped space, divide it into rectangles and triangles to get the measurement. Add up the square footage of each section.
- For areas like behind the stove or around windows, take separate measurements just for these spaces.
Having accurate measurements is key for determining how much tile you need. Measure carefully and even double check your math.
Calculate Square Footage
Once you have the measurements, it’s simple to calculate the total square footage:
- Multiply the length by the height for each section.
- Add together the square footage of each area to get the total.
For example:
- Main backsplash area: 4 ft high x 10 ft long = 40 sq ft
- Behind stove: 2 ft high x 3 ft wide = 6 sq ft
- Total = 40 sq ft + 6 sq ft = 46 sq ft
If you have multiple accent sections or irregular shapes, do a separate square footage calculation for each then add them up.
Having the total square footage of your backsplash is essential for estimating tile requirements. Write this number down to use in the next step.
Estimate Tiles Needed
Most backsplash tiles come in sheets sized at 12″ x 12″ or 12″ x 24″. With the total square footage amount, you can calculate how many tiles are needed:
- For standard 12″ x 12″ tile, divide total square footage by 1 square foot (144 square inches).
- For larger 12″ x 24″ tile, divide total square footage by 0.5 square feet (72 square inches).
For example, if you have 46 square feet of backsplash and are using 12″ x 12″ tile:
- 46 sq ft divided by 1 sq ft per tile = 46 tiles
If using 12″ x 24″ tile:
- 46 sq ft divided by 0.5 sq ft per tile = 92 tiles
Round your tile estimate up to the nearest full number to ensure you purchase enough. It’s better to have a few extras than to run short during your project.
Also add an extra 10% more tiles to account for broken or damaged pieces and allow for cutting. If your estimate was 46 tiles, purchase at least 50-55 tiles.
Consider Other Factors
A few other things to factor into your tile calculations:
- Tile orientation – Installing subway tile vertically will require more than horizontal layouts. Adjust math accordingly.
- Grout lines – Smaller grout line width means you’ll need more tile. Allow for 1/8-inch grout lines in estimates.
- Pattern design – Intricate patterns like herringbone require more tile due to shaping and angling pieces. Simple patterns are most efficient.
- Trim pieces – Calculate linear feet needed for edges and niches. Purchase extra for mistakes and cuts.
Taking these design factors into account will help you buy the right tile quantities you need.
Purchase Extra Tile
It’s always a good idea to purchase 5-10% more tile than your calculations estimate. This provides extras in case:
- Tiles become damaged during installation.
- Complex cuts result in unused pieces.
- Minor measurement or math errors were made.
- Replacement tiles are needed for repairs down the road.
Having spare tiles on hand ensures you can complete your project and do future repair work. The small extra cost is worth it for peace of mind.
Carefully Measure and Calculate
Installing a backsplash really amps up your kitchen’s style. By carefully measuring your backsplash area and using square footage math, you can accurately estimate how much tile is required. Allow for extras due to damage or complex installations. With the right tile quantities purchased, you’ll be set up for a successful project.
Frequently Asked Questions
How do I calculate square feet for irregular shaped backsplashes?
For irregular shapes, break the area down into smaller rectangles and triangles. Calculate the square footage of each section then add them together to get the total square feet.
Should I calculate tile needed by the square foot or by each tile?
Figuring tile needed by the total square footage rather than counting each tile separately makes it easier to estimate quantities. Divide total square feet by the size of your tiles.
What size tile requires the least amount?
Larger tiles require fewer pieces to cover the same square footage. A 12″ x 24″ tile needs about half as many tiles compared to a 12″ x 12″ size. However, smaller tiles allow for more design flexibility.
How much extra tile should I buy?
It’s recommended to purchase 10-15% more tiles than your measurements estimate. This provides extras to allow for damages, complex layouts and future repairs.
What measurements do I need for subway tile?
For subway tile layouts, measure the height and length of each backsplash section. Also calculate the perimeter if doing a border or trim. Include niches and stove areas separately.
Conclusion
Calculating how much backsplash tile you need takes a few simple measurements and math. By measuring square footage, estimating tiles, and allowing for extras, you can buy the right quantity of tile for your project. With careful planning and purchasing, you can create a beautiful, professional-looking backsplash in your kitchen.
