Haven't taken an algebra or geometry class in a while? We've got you covered! While your Fireclay Tile Design Consultant can't provide your final quantities for you (let's face it, they've never been in your space), we've created a helpful math "cheat sheet" so you can feel more confident when it comes to placing your Fireclay Tile order.
Pro Tip: We always recommend getting your final quantities, including overage, from your contractor or tile installer—they're the experts! For your own reference use these handy calculation worksheets:
Calculating Square Footage
For today's math lesson, we'll be calculating quantities for this sample kitchen backsplash made by our rendering artists using our 2x6 ceramic tiles in Tusk and Clover.
1. Divide the Space
We recommend dividing your space into smaller sections to keep things simple. In this kitchen, it makes the most sense to divide the entire backsplash into three sections—Left of Window (A), Under Window (B), and Right of Window (C):
2. Measure
Next, you'll want to get dimensions for each section—the height and also the width so you can calculate the area of your space. Use a tape measure to get the exact dimensions of your space's sections.
Notice how all of our measurements are done in the same unit—inches. Depending on your preference, you can measure in centimeters, meters, inches, or feet—just make sure you're consistent in your units throughout your math calculations.
3. Calculate the Area
To determine the area of each of your sections, A, B, and C, you'll want to multiply the height of each section by the width of each section.
A = 36" high x 54" wide = 1,944 square inches
B = 6" high x 62" wide = 372 square inches
C = 36" high x 48" wide = 1,728 square inches
Add all three sections together to get your total area needed:
A+B+C = 4,044 square inches of material needed.
4. Know How it's Sold
Typically our made-to-order brick, glass and ceramic tile is sold by the Square Foot, our Quick Ship Tile by the box, our trim by the Linear Foot, and our Handpainted Tile and other specialty items by the Piece. Knowing how our products are sold is helpful when determining your quantities. In our kitchen backsplash example, we're working with made-to-order tile which means we'll need our final quantities in Square Feet.
To convert square inches to square feet, simply divide your total square inches by 144 (the number of square inches in one square foot).
4,044 square inches divided by 144 square inches in a square foot = 28.08 Square Feet!
5. Add Overage
Because you're working with a handmade material that has lead times to make, it's important to order more than enough material to finish your project (while keeping some material for attic stock).
In the event that you need additional tile, you have 30 days from receipt to request an Add-On Order, and orders under 25 square feet incur a small batch fee. Standard lead times should also be considered unless you opted into our Installation Protection warranty for your original order. Keep in mind that we can't ever guarantee an exact color match between orders, even with a control sample.
We generally recommend adding at least 15-20% overage to your final quantities. If you are installing your tile in a pattern like a herringbone where more cuts will need to be made, we suggest bumping up your overage amounts to a minimum of 20%.
In our kitchen example above we would take 28.08 total Square Feet + 15% = 32.29 Square Feet. We can't make .29 of a Square Foot, so instead, we would suggest you round up to the nearest Square Foot—33 Square Feet.
Calculating Trim
For our sample kitchen, you can see that Sections A and C have open ends on the top and outer sides of the backsplash, where glazed edge or bullnose trim would be appropriate.
Like your samples, the edges of our tiles will not be finished. If the edges of your tile will be exposed in your space we can finish them for you. We offer many trim options from classic bullnose to elaborate architectural moldings. Learn more about our trim here.
For the most part, trim is sold by the Linear Foot. In our example above, we already know the measurements of the sections that would need trim: the width of the sections are 54" and 48", the height of Section C is 36", and the height of the open edge on Section A's left side is 6".
54" + 48" + 36" + 6" = 144"
We now just need to convert this unit to feet since that's how it's sold. There are 12" in one Linear Foot so simply divide 144" by 12" in one Linear Foot to get 12 Linear Feet!
Don't forget to add some overage to your trim quantities as well. We recommend 15% overage.
12 Linear Feet + 15% overage = 13.8 Linear Feet.
With trim quantities, we typically recommend rounding up to the nearest whole foot—so 14 Linear Feet in this example.
Math Conversion Cheat Sheet
Depending on how you did your calculations versus how things are actually sold, you may have to do some of the following conversions:
Pieces to Linear Feet
Whenever you're doing conversions, you'll first need to know what side of the tile you're focusing on. If you're working with a square tile, orientation won't matter because each side has the same measurement. However, if you're working with a rectangular tile, orientation will matter because there will be both short and long sides. For example, in our kitchen above, we focused on the long, 6” side of the 2x6 because that was the side that was exposed in the space.
If you have the total number of pieces you need but are looking to convert to linear feet, simply multiply the number of pieces by the length of the tile in question. Next, divide that number by 12 because there are 12" in one linear foot.
Example: 200 pieces of 2x6 to Linear Feet (focusing on the long, 6” side):
200 Pieces x the 6” side divided by 12" per one Linear Foot = 100 Linear Feet!
Linear Feet to Pieces
Let's reverse our math example above (reversing your math also helps double-check your work!). If you have the total linear feet, but the product is sold by the piece simply multiply your Linear Feet quantity by 12" (because there are 12" in one Linear Foot). Next, divide that number by the total length of the piece in question (6" in our example).
Example: 100 Linear Feet of 2x6" to Pieces (focusing on the long, 6" side):
100 LF x 12" per Linear Foot divided by the 6" side = 200 pieces!
Pieces to Square Feet
If you have the total number of pieces you need, but the material is sold by the Square Foot, you'll first need to determine how many pieces of the material are in one square foot. This information can be found on our Size Page. Click into your desired size, and the number of pieces per square foot will be listed (you can also ask your Design Consultant):
Once you have that information, take your total number of pieces and divide by the number of pieces there are per Square Foot (there are 11.5 pieces per Square Foot in our 2x6 example).
Example: 200 pieces of 2x6 divided by 11.5 pieces per Square Foot = 17.39 Square Feet.
We can't make .39 Square Feet, so you should always round up to the nearest square foot. In this example, we would round up to 18 Square Feet!
Square Feet to Pieces
Again, you will need to know the total number of pieces per square foot to do this conversion. Once you have that number, reverse your math and multiply your total number of square feet by the number of pieces there are per square foot.
Example: 17.39 Square Feet x 11.5 pieces per Square Foot = 199.9 pieces. Again, we can't make .9 of a piece, so you would round up to 200 pieces!
Being able to convert Square Feet to Pieces will be very helpful when it comes to buying handpainted tiles since those are always sold by the Piece.

To get from Square Feet to Linear Feet, you'll first want to convert your Square Feet to pieces, and then from there, you can convert your pieces to Linear Feet using the steps above.
