Font size of forwarded messges too small

When I forward a message, the font size of my new message and the header of the forwarded email are fine, but the body of the message is unreadably small.  How do I remedy this?

Hey Nicholas,

Go to Menu -> Tools -> Settings -> Mail -> Templates and Signatures, add a template and configure it with your preferred font and font size, save that template and set it as a template for new mails, replies and forwards.
