what version of TB?

for viewing:
Tools->options->display
  default font -> size  (i use arial and size 16)
    and take a look at the advanced button and set those sizes, too...

    i use these for advanced
      fonts for Western:
       proportional: sans serif        size 16
              serif: times new roman
         sans-serif: arial
          monospace: OCR-A Extended    size 16

for writing:
Tools->options->composition
  HTML section
    font -> size

    i use OCR-A Extended size medium here...

generally speaking, i prefer to use OCR-A Extended for all because it is
monospaced but some things have glyphs that that font can't show... the
proportional setting above allows for only serif or sans-serif... all the
others i can choose OCR-A extended if i desire... i just haven't (yet)...

FWIW: my monitor screen is also set to 1600x1200 so i have a lot of real
estate on my 19" screen...

FWIW2: you should also be able to hold your CTRL key and scroll your mouse
wheel to make the size larger or smaller... CTRL-0 (zero) to return to
normal... if the mouse wheel thing doesn't work, i think CTRL-1, CTRL-2,
etc will make the fonts larger as you go...
