Wilton Wedding chart, http://www.wilton.com/wedding/wedding-cakes/wedding-cake-data.cfm , which is what I go by, shows:
6=12 servings
10=38 servings
14=78 servings
Total = 128 servings. If you don't count the top tier, it's 116 servings.
I use an 8/12/16 for 180 servings.
Here's a link to my website that shows you how to cut a cake to achieve Wilton Wedding servings. I actually get about 10% more servings when cutting it this way instead of the dreaded circle method: http://cateritsimple.com/_wsn/page10.html
Here's a pic of cut pieces of wilton size cakes: http://www.cakecentral.com/modules.php?name=gallery&file=displayimage&pid=1156785
since that is the standard that most use please go with the sizing that indydebi gave
