The font size of ETS Viewer is too small. How can I increase it?
Screen resolutions vary quite a lot and so it is possible that on some machines the default font size may look too small or too big. To alter the font size, you may either use Tools -> Font Size menu for small changes or you may run ETS Viewer with a command line option that allows you to alter the font size like this:java -DfontSizeIncrement=10 -jar etsviewer.jar
You can specify however large increment you want in the font size.
If you have a high resolution/4K monitor that is causing the ETS window to become very small, try these solutions.
