I don't know answer to your question, but why not use both in alternating courses? I had oak floor (until flood) that alternated 3", 5" & 7" courses. Alernating 6" & 9" might make look more like natural wood. Maybe add'l cuts due to req'd offsets? A guess.

ChiFlipper is right. I did w/ both my tile projects.

good points :) not buying yet, nor did the person doing the measuring come to our house. We still need to take out our old cabinets and rip up the current floor. I too was thinking alternating 6 and 9. The real wood floors throughout the rest of our house are all the same width, engineered oak. I thought I heard someplace that you can only do the thinnest grout line possible if you use the same size tile and not alternate. Has anyone heard that before? I was also thinking to have it installed diagonal rather than straight. That too I was told more cuts for diagonal than for straight. How could that be, because you have to cut no matter what once you get to the end of a wall no matter what direction it goes.

anyone else who might have installed 6x36 or 9x36 or both alternating together same room? :)

I've never seen 9-inch planks of real wood, so if you're going for a naturalistic look, I'd stick with the narrower tiles.

I imagine that there would be more cuts with the wider because it's more likely that you'd run into various obstacles (doorways, corners) with the middle of a tile rather than being able to line it up on one side. but that's just a guess.

This is a rough estimate; square footage plus 10% for waste, now add another 10% for a diagonal lay. Again, consult your installer for the "best looking" way to lay the tiles. A really good installer is the key.

acm, we are doing wood look tile :) That is part of my problem, how to determine a really good installer. 3 places I contacted already, I know 1 of them contracts out. Not sure of the other 2, but I know they said they could install it.

Two of them have a few stores within our general area. Have one more local business to contact to see what their costs would be. They do the installs themselves, and wondering if they would be slightly less and possibly better job at installs. They also do wood floors and design bathrooms.

we decided on another wood look tile that seems to be a better color for our kitchen, and also a bit lower in price including the install, This is a photo I took at the local business that is going to be doing the install.

I also took the website graphic of the floor and pasted a photo of one of our kitchen cabinets (not completely finished installing hardware)
It only comes in 6"36" planks. Its brand Happy Floors and the style is Hickory in the color Cherry.

Thought it worked well with our Cherry cabinets that are stained a warm Walnut. Even the owner of the store recommended this color once she saw my drawer slab I brought with me
