How can I scale down everything that Lilypond is outputting?

Question

How can I scale down/shrink everything that Lilypond is outputting so that I can fit more material on each page? I tried using

\layout{
    #(layout-set-staff-size XX)
}

inside the \score{} block (where XX can be any number), to just change the staff size, but this screws up the overall look and relative dimensions, so it's not what I want.

Answer 1

I think that you want

#(set-global-staff-size XX)

Here is the lilypond 2.19 staff size documentation (also works in 2.18).

Note that you don't put this command inside the \layout block; the following is what I've tested/verified (v2.18) in constructing this answer:

#(set-global-staff-size 36 )
\relative c'{
  c d e g f g a c e e d2
 }
