I found that on Jzool it doesn't say the size of the squares (which are equivalent to the size of the stones) so I'm not sure that the stones that I have which are 9.2mm tall and 21mm wide (about 3/8'' x 3/4'') will work for the board I want to get (because I want to get a goban floor board. Does anyone know the size that the stones work for I'll update this if I find out. Thanks I'm assuming all the boards have the same size made for the same sized stones but not quite sure if that helps anyone.
