I would use a 1/4" x 1/4" square notch.. after placing the tile in place and pressing it into the thinset, remove it and check for your coverage. You should see that there is thinset over 80% of the tile.

If you do not see 80% coverage on the back of the tile, step up the trowel size or your application method of how you're using the trowel.. stand it up more comb with less pressure, etc..

1/4 inch and no problemo

If the tiles are smooth on the back, and the walls are quite flat, you can even use a 1/8" 'U shaped' trowel. This might help keep the morter from squishing out between the tiles as you set them. As always, put up a couple of tiles and then remove them to check for a good bond. If you are using thinset, mix it a little on the "loose" side....not runny, but loose. It should hold a ridge...but just barely.

yup, the back of the tile and substrate would have an effect on what size trowel is being used.
