How to calculate square footage {backsplash}

Use your ← → (arrow) keys to browse

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.

I knew I was in trouble when the tile guy said, “how many square feet do you have?” Umm, I’ll call you right back on that.

Measure length x width (in inches) and take that total number and divide it by 144.

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.

If you are anything like me, math makes my brain hurt and that’s why I hang my pictures and shelves with painters tape. Be sure to check out that painters tape post if you struggle with measurements. ha.  How to calculate square footage really isn’t that difficult once you do it a couple times. Hopefully for those of you with simple math brains like me, this helps you move forward with your backsplash project and how to calculate square footage.

    Ha, I too have a college degree and have to google “how do I calculate square feet” every so often. What’s up with the “144” anyway? My dad told me to “look it up” just like the time when I was little and wanted to know how to spell pneumonia. Some of these rules just hurt your brain! Could you please ask gramps what’s up with the “144”? :)

      Awesome tip! The 144 is because there’s 144″ in a sq ft (12″ length x 12″ width). I always remember this by the size of 1 floor traditional floor tile (like in schools, which is where I learned that).

        See, you were paying attention in school! Thanks, now I will not ever have to google or ask pops again…haha!

    Thank you for the tip! Now my husband will think I’m so smart because I won’t have to ask him :-). Love the blue back splash.

    It the same for measuring floors.

    This is why I became a hairstylist! :-/ This really brought back the memories of why I disliked math so much. Thank you for posting this because it completed my measuring backsplash experience. Now I can order my tile.
