Smallest font style in MS word?

What is the smallest font style in MS word, we were given a maximum limit of two pages for a product design research sheet (which is absolutely ridiculous), and a minimum font size of 11, the smallest font style we found yet is Arabic Typesetting (its 11pt looks like 7.5pt Times new roman),

Just wanted to ask if anyone here knows something that might be smaller

Any help would be appreciated!
