We will now adjust line spacing in Google Docs based on the font used. Previously, line spacing was based only on the font size and line spacing you chose. Now, the font you choose will also be a factor in the spacing. 

This will increase consistency in document length between Google Docs and other word processing programs, and help make sure converted Microsoft Word documents retain a similar length. It will be particularly useful for education and enterprise users, who may have documents with specific length requirements based on specific formatting combinations.
