Can u increase font size in safari

Is there someway to increase the font size in safari? The zoom feature is impraticle for reading fan fiction it is too slow and annoying to pan horizontally over lines of text. Or do you know of an app that would let you browse pages and increase font. Goodreader doesn't work for download pages from safari. Their font changer goes away my safari download pages. Only works on PDF files. Any help? At 50 my eyes could use a bit of help.
