Yes, it does.
The usual sett size is between 6"-8", it doesn't mean you can't work to a different size. but that rough size seems to work will with much kilt work.

With the tartan you linked to, it appears that there are a number of lines which are are only one or two threads wide, so it would likely lend itself well to increasing the size without making the sett appear too bulky. In other words, it has the room to grow.

Thread counts are almost always in even numbers not in singles, as two warp threads are needed to make a decent visible line in the tartan
