The base font size of a document is the most common font size in that document, i.e., the size of the bulk of text in that document. When you specify a Base font size, we automatically rescales all font sizes in the document proportionately, so that the most common font size becomes the specified base font size and other font sizes are rescaled appropriately.
For example, "Mikhail Gorbachiov" will be replaced by "Mikhail Gorbachiov."
