Product Page Font

Where would I change the font and font size for the product page?

Assuming you mean the product info page, it would be #productDescription in the stylesheet. Add it if it isn't already there.

Ok this is what I see:

/bof product info/
#cartAdd {text-align: center;margin: 1em;border: 0px solid #000;padding: 1em;float:right;}
.product-divider {border-bottom:1px dashed #ccc;}
.navNextPrevWrapper {text-align:center;}
.navNextPrevCounter {text-align:center;}
#productDescription {color:#444443;}
#productName {color:#444443;font-weight:normal;font-size:2.0em;}
#productDetailsList {color:#444443;margin-top:10px;margin-bottom:10px;}
#productAttributes {}
#attribsOptionsText {font-weight:normal;color:#444443;}
.optionName {color:#444443;margin-top:0px;}
#alsoPurchased {margin-top:20px;}

I meant to say I want to change the font for the product NAME to Times New Roman and the font size to 12 pt. What is the equivalent of 12 pt in em?

So only change #productName add: font-family:"Times New Roman",Georgia,Serif;
