The Stata Results window has an icon in the top left corner (see below) that you can click and bring up a menu to select the font. Below we show an arrow pointing to this icon for the Review window. For other windows, you can right click on the window and then a menu pops up allowing you to select the font. The font changes you select are saved from one Stata session to the next. If you want to change the font for each window, you need to do this process separately for each window, allowing you to choose a different font for each window.
