Font too small to read in DTTG

I’ve got my font set at 12 Helvetica in DTTG on my iPad and I can barely read it unlike other ipad apps. I want the size to sync over to my iMac as this size but i can’t read it very well in DTTG. Is there anyway to make this appear larger without it actually being larger in print than 12 point.

Yes. However, the problem is just their display of a font. So Helvetica 12 is what I want for printouts however, in DTTG it is extremely small to read. Other products are quite different and the font is nicely readable.
