The largest possible single letter on one page

[homelea]

I want to print out a single letter on one page for a banner I am making for my daughters school leavers party. However, if you make the font size too big it slips onto a second page and it will only fill half a page at its largest. For example, I want the letter 'S' to fill a whole A4 page then the letter 'T' then 'B' etc. I will then print then out and stick them on the banner. Any solutions very gratefully received

Um, adjust the margins?

I'd suggest using an drawing program, even the most basic ones will do. Create each letter as in illustration.
