I am currently working on a small exhibition for university alumni. Because of budget and the lack of visuals, I will be relying on mainly on typography. It would be great if I could pick the brains of the more experienced designers here.
I am just wondering if there is any rules of thumb for determining type size when reading from a wall (or is it just a matter of testing it out?). In particular, how would one size lengthier blocks of text, such as the introduction. What other considerations should I keep in mind when designing in this context?
Thanks in advance!
