Hey there Big Bob - 1/4x1/4 is fine, you might even go a little smaller, like 3/16x1/4 Vnotch if you want. I just started using wedge spacers for walls and love them. They're easy to adjust, just push them in or pull them out a little more. I used them for the first time on 12x12 travertine in a shower and they rock!
If you're going to be doing any floor tilewith spacers in the future, you can get 1/4" or 3/16" spacers and turn them on edge for thinner lines on the wall.
