Generally with rectangles it’s better to break it down by width and height- ie - 263 / 6 is about 44 tiles wide, 19/3 is about 7 tiles tall (rounding up) 7x44 308. Add 10% for breakage and whatnot. More if you have lots of things to cut around. 400 def seems too high. Answer from peteschirmer on reddit.com

How do I calculate how many tiles I need for my living space?

Well the first step is to measure the room space. Example: Room Floor 1 is 10’ x 10’ which = 100 sq ft Now go pick your tile out and make sure to get 100 sq fit. Buy a little more to ensure you have enough in case of tile breaks, cracks, etc. Best of luck

r/DIY on Reddit: Help calculating how much tile I need - am I missing something here?
November 19, 2023 -

Want to install a backsplash in my kitchen. The area I want to cover is 19" tall by a total of 263" long.

Looking at these 3" x 6" tiles from Lowes.

When I use their calculator, it's telling me I need close to 400 tiles.

My thinking is 263" * 19" = 4,997 sq. inches.

4997 (total area) / 18 (tile area) = 277.6

Even if I added an additional 10% for screws ups and whatnot, I'd come out to like 305 tiles. Is my math correct here or am I not thinking of some factor?
