I've been wondering if there's a universal grid structure to use regardless of format/page size/proportions? While researching online or reading professional books i usually can see that there are a lot of examples of many division types but never a guideline to start with in any occasion.
I started experimenting with dividing length and height of any format i worked on by 10. Which gave me always 100 modules with exactly the same proportions as the the whole format. Then i read web designers usually use 12 or 24 modules horizontally because the're easily dividable by 2,3 and 4.
So i started dividing each format's length and height by 12. Do you have any suggestions, what other approach i could use in any situation regardless of the graphics material type (posters, ads, posts, catalogs etc.)? Maybe something related to golden ratio, Fibonacci sequence or musical proportions?
