90 degree herringbone grout line issue

Demand · Feb 4, 2023

I’m trying to do square (straight) herringbone with a 4x12 tile. I’m not getting the math on how you can do it if you add grout lines to horizontally laid tiles. If I add 1/8 line the width becomes 4 1/8 and 3 tiles horizontally are now 12 1/4. I see examples on the web but no one mentions how to handle the extra width. Any help is appreciated.

The short length side of the the tile has to fit perfectly along the long length side of the tile perfectly for herringbone to work. If it doesn't ( grout joint included ) then herringbone isnt possible.

thanks. It’s that simple for me too, now trying convince my wife it won’t work. She’s now trying to convince me to do a traditional herringbone which I explained is the same thing just turned to a 45.

Is it not because the Herring bone, once laid would have a 45 deg angle, not a straight tile edge at the margin?

I've come across this very problem on my current job which is the first time I've attempted herringbone. My tiles are 200 x 100 (exactly). I've been pulling my hair out for several weeks now. I did manage to devise an extremely convoluted system to do it however it's been a nightmare and one I won't be repeating. I've been using a combination of 2mm and 3mm spacers. Horror. What can I say, it was too late to turn back. Would I be right in saying then that the correct tile size would be for example 202mm x 100mm, for a 2mm grout line?
