How to increase the size of the text in Windows 3.1

Double-click on Windows Setup in the Main group of Program Manager. Choose the Options menu, then Change System Settings... from within the Options menu.

A list of all installed video drivers will be displayed. Your current video driver will be highlighted. Choose the same driver as you are currently using, but with "(Large fonts)" displayed after the name. For example, if the currently highlighted driver is "ET4000 800x600 256 col. (Small fonts)", choose "ET4000 800x600 256 col. (Large fonts)" instead.

Click on the OK button.

You may be asked if you want to use the currently installed driver. Choose the Current button if you are asked this question.

You may be asked for the video driver disks that came with your computer or the Windows master disks. Insert disks as the computer requests them.

Once the installation is completed, you will be asked if you want to restart Windows. Click on the Yes button.
