How do I increase font size in gmail? Outgoing as well as incoming email.

i tried dking what you said on my iPad retina to increase the font size on my incoming & outgoing Gmails. However I don't have an option for " vision" following General>accessibility>(vision)?

My options are General >accessibility > Larger Text. Lattter opens up a slider scale but moving the slider even to the biggest setting doesn't change my text size in my Gmail incoming? Any comments? Jimmyd

Settings > General > Accessibility > Vision > try changing the Larger Text and Bold Text settings until the results suit you.
