Resize Descending tree

Hello,
I want to make a descendant tree for a family party. But the family is very large (+/- 200 members) and we can’t read all the names in the graph. Is it possible to modify the size of the tree (even if I have to print it on A1)?
Thank you very much.

There are other threads that talk about printing over-sized charts and adjusting the Font Size for that.

There are others too… several different objectives are discussed in other threads.
