When you run Windows command line, you will find a small window opens – something that may not be very comfortable on the eyes. You have two solutions to fix this.
The first is to enlarge the window as you would any other program by clicking on the button to the top right, or by selecting "Enlarge" from the menu.
The second consists of going into the programs properties and selecting "Properties" by clicking on the icon to the top left of the window and then selecting "Layout". The advantage of this is that you can select the window size you wish to use by default as the settings will be applied each time you run the program.
