for diferent size tiles are there standard grout joint sizes
It depends on the size of your tile. A lot of 4.25 inch tiles have spacers built in. When you put the tiles in it will give you a 1/8 in gap for you grout. I use 1/4 inch spacers when installing 12 inch tiles.
This doesn't directly answer your question, but I thought that you might like to know what can happen if you don't make a grouted joint in ceramic tiles, particularly in a shower cubicle. The tiler who tiled my shower room didn't make any joints at all. He set the tiles so close together that they were touching, presumably to save on grount and on time. That's what caused a leak in my shower cubicle, strangely enough. The water washed off the tiny amount of grout that was wiped over the tiles, then it worked its way through and behind the tiles, and appeared as a wet patch on the carpet in the hallway outside the shower room. All this took several years to show up. I had to have the shower cubicle retiled, with 3 or 4 mm grouted joints, plus new plaster board backing, but it solved the problem of the leak. So, that's what could happen if you don't put grouted joints in ceramic tiles, particularly if they are in a shower cubicle.

There is not set standard but most people use a 1/4 joint and I m assuming your using a tile that uses a sanded grout. I personally like to use a 3/16 joint but this depends on the type of tile. Cheaper tiles are not sized and made as well as a more expensive tile like a porcelain. Then I use a 1/4 joint. Some less experienced people will use a 1/4 because its just a bit easier to work with.
