Resizing AND scaling a dynamic text field

i’d like to know how i can resize a dynamic text field’s width and height (to hold certain lengths/lines of text) by defining these properties in an xml file without scaling the text.

second, i’d like to know how to resize the same dynamic text field’s width and height to actually scale the text - again properties defined in xml.

the reason i need to do both is that while i’d like to have text in a standard size wrap in text boxes of various widths, there are some areas of my project where the area is too small to use the default text size so i need to scale it down a bit to fit.

any help would be appreciated.
