Increase the font size of output and menus in NetBeans

On Windows 10 editing netbeans.conf (appending the --fontsize 16 to netbeans_default_options) normally should work (at least, it works for me with the latest NetBeans). Another solution is to start netbeans.exe with --fontsize 16 option. For instance, having a shortcut to NetBeans on a desktop, you can modify it in the following fashion: right-click on the shortcut, click Properties, select Shortcut, append to the target line --fontsize 16.

Go to the bin directory where Netbeans is installed. Generally the defualt is : C:\Program Files\NetBeans <version>\bin. Now through Command Prompt start netbeans by: netbeans --fontsize 14 --console suppress. By using --console suppress you can close the cmd window, without affecting the netbeans window.
