Everything? including the paper?

Yes, if you want to make the music larger on each page, with
fewer measures/line and lines/page, and using more pages.

#(set-global-staff-size 20.0)   is the default. Increase or
decrease accordingly.

Oh, scratch the previous paragraph. Just find a viewer that's
able to increase and decrease the magnification. (Don't they all?)

That suggests that it's not obvious how you should be controlling
your viewer. Tyically, you'd put your fingers on the screen and
slide them apart to expand the display, or you'd select
magnification factors from a menu (or, as I do, have predefined
keystrokes, 0–9, z, h, w, that set preferred magnifications,
100–2000%, fit to page, height, or width).

So it depends on which you and your wife want.

Cheers,
