What size graph paper is best for point and figure charts?

In many respects, the larger the sheet of paper you can get the better, however, computers have replaced hand drawings in so many areas that it is difficult to get other than A4 sheets now. They can be taped together if necessary.

I know that is not what you meant, but I thought I would add it anyway.

I guess you are asking about the grid size. I found 2mm grid was the best compromise. If you use smaller than that, you can get more on a sheet, but it will ruin your eyes.
