Best Answer

It is impossible to change the font size of the text (such as layers name) in the Table of Contents in ArcGIS. You cannot do this manually or with ArcPy. It might be possible to do with ArcObjects, but it would involve heavy development effort.

Your option is to use Windows settings:

Go to Start > Control Panel > Personalization > Window Color and then choose Icon. In the lower panel choose Font Size. This is the option that controls the font of the name of the layers in the ArcMap TOC.

while elm.elementWidth > float(elmWidth):
    elm.text = '<FNT name="Arial" size="' + str(x) + '">' + elmText + '</FNT>'

[GIS] change the font type in all Text_Elements in a page

The Text Element class of the Mapping Module has no font property. This leads me to believe that there is currently no method for changing the font type of text elements through arcpy's mapping module for now. The help even has a code sample for changing the font size of a given element, and its best idea is to do what essentially is a looping test of length edited by HTML code similar to what you use above. Perhaps this will be rectified in later iterations of the mapping module, but I do not have high hopes.
