Many of us use our iPhones for email and messaging purposes. Sometimes it may seem that the text of mail on iPhone is really small. There is a way to change mail font size on iPhone and this tutorial will teach you exactly how to do that easily and in no time at all.
1. Open the Settings.app on your iPhone
2. Tap on Mail, Contacts, Calendar
3. Now scroll download and tap on Minimize Font Size
4. From the list select whether you want large or medium font size
There are other options available as well, namely Giant and Extra Large. These options are aptly named as the text literally gets humongous and too big. Medium and Large are the too settings you'll probably want to use as they considerably increase font size without making it so big that it becomes a nuisance to read such big text.
