How to Calculate Backsplash


Back spatter is a moisture that settles on the top of glass or ceramic tiles. This can cause a number of issues in a kitchen, staff and client communication, or simply a lack of decor. Luckily, how you calculate backspatter is actually quite simple.


Dad, “how do you figure out square footage?” I am going to confess, prior to installing our removable kitchen backsplash, I was not sure how many tiles I needed and how to calculate square footage was making my brain hurt. Would you believe me if I told you that I had my painters tape out and was mapping it out on the wall and trying to determine how much tile I needed? Oh yes, my dad came home from lunch one afternoon to find me taping off our backsplash in the kitchen. Needless to say, I learned fairly quickly how to calculate square footage.

In my case, this particular wall was 13 feet (156″) in length and 1 foot (12 inches) in width for a total of 1872 inches (156×12). Divide total inches 1872 by 144 (total square inches in a foot) = 13 (square feet). Math was not my strong suit in school so that little o’l “144” threw me off! ha. My dad said, “all that money I spent on college and you can’t remember how many square inches in a foot?”. Nope, I think I skipped that day. I am happy to say, I know how to determine square footage now. (Source: www.fourgenerationsoneroof.com)


Your grout line area will be considered as cutting waste and is not added to the calculation. A backsplash with diagonal cuts should have a waste allowance of at least 10 percent. Because tiles come in batch and dye lots, you should always purchase extra tiles and store them in a dry area in case you need to replace a tile in the future.

homeguides.sfgate.com)You’ve reached a dilemma in your remodeling project: You want to estimate the material costs but can’t figure out how to calculate the amount of tile needed for the backsplash. Unlike flooring, which is calculated in square feet or square yards, tiles used for backsplashes are often less than a foot square. Calculating the amount of tile you'll need requires that you first determine the backsplash area and then figure how many tiles you will need for the job. (Source:
