RISE 360 - font size and accessinility

I am having a hard time understanding the font size in Rise 360. It appears much smaller than what I set it to. 12 point is much smaller 12 point in Word or any other software I use. In Rise 360, 14 pt text is smaller than 12 pt in word. Are these numbers intended to be point or some other text system like pica? I do not believe that the courses I have created in Rise 360 can be used at so called 12 point. What font size will be considered accessible in Rise 360. When I set the font to 18, it looks like 14 pt.
