Often in presentations, there is requirement of increasing size of content in SSMS. Until now, we used to use some third party softwares. Now SQL Server 2012 provides an option to increase/decrease the size.
We can individually configure the font-size for both query pane and results pane. In bottom of query pane and results pane, you can find the size combo boxes. By changing the size value in that combo boxes, you can increase/decrease the font-size in these both panes.
