Using formatted name as form header

Hi, beginner question here.  I'm setting up a simple database of birds, showing one species per form view. The first field in the form is SpeciesName, and for easy reading I'd like that to appear in large bold type.  But the manual recommends not using text (formatted) as a substitute for normal text fields, as sorting may be affected (I assume that text (formatted) is an old name for what's now called Rich Text).

Is there a way of achieving what I want?  I'd be happy to use an ordinary text field for data entry with a separate calculated/copied field for display purposes, but can't work out how to create a function that would result in formatted text.
