That is we could easily read the 'Courier new' font face. So there are 3 easy steps, following which we could change the font-size of editor of Adobe Dreamweaver.
These steps in black and white are as follows:
1. Press shortcut command 'Ctrl+U' or Go to Edit menu-> Preferences or if not possible then look at tool bar placed at Left. (just check out these images please.)
2. Click this and it will pop up a new window which is titled as 'Preferences'. here you will find various settings where you would find a tab labeled as 'Font'
3. This place is what where you can give value as per your comfort level.
