The grid that we use is very important. You can virtually do anything with it. Although writing is flexible, the paper you use comes in different sizes. I was thinking about the golden ration in regards to Typography and here it comes. Font ratios 5-8-13-21-34-55-89, as well as 6-10-16-26-42-68-110, and 4-7-11-18-29-47-76, are ascetically pleasing. Page proportions are also very important as well.
