I have a 6.5 inch square Omnigrid and I like that size for small pieces. But recently after reading a recommendation on here about Creative Grids, I bought the 12.5 square to try out since I needed to replace my original one. I love it! It is easy to read and doesn't slip around at all. So I am in the process of swapping out all of my Omnigrids for Creative Grids. Found the 6.5 x 24 on sale, locally, yesterday. For you, I would recommend CG 6.5 square for sure.
