shrink to fit for microsoft word

How to find and use 'Shrink To Fit' in Microsoft Word for mac. I have seen a few answers to this, but, none seem to grasp what 'Shrink To Fit' is. Shrink to fit allows the user to take one or more pages and shrink the content of those pages onto one page and sometimes just fewer pages. It does not as is indicated by many answers require the user to reduce fonts or letter sizes manually or reformat the page. It simply shrinks or resizes the area over which the document is spread. For example, I have one and a half pages of printing but I want it all to reduce to one page for easy reading. For anyone who has used Microsoft WORD on a PC they understand 'Shrink To Fit' is achieved by clicking one button from the ribbon. Is this function completely missing from WORD for apple computers?
