Dear PNR,

Access the page number placeholder on master slide and then change the font size.

e.g

Slide masterSld = pres.MainMaster;
Placeholder phld = masterSld.Placeholders[footerIndex];
TextHolder thld = phld as TextHolder;
thld.Paragraphs[0].Portions[0].FontHeight = newFontHeight;

Please see this thread, how you can get the footerIndex
