How narrow can my margins be?

Hello friends, I want my margins to be as narrow as possible? How narrow can they be? Also, what is the recommended font size for older people?

Hi Craig,
I’m not sure what you’re trying to achieve, but at least you’ve helped us identify some interesting bugs along the way. I discovered that you can’t use a Side Margin Width of 0.0mm - it causes an exception :frowning:

But other than that you can do silly things as can be seen below. BUT PLEASE DON’T!
