Goto How to Change the Default Format Settings in Eclipse
Follow the steps to create a new profile. Step 11 [Line Wrapping] shows a 'Maximum line width' field, changing that would fix your issue.
Also, make sure your newly created profile is selected in the Active Profile drop-down inside Window -> Preferences -> Java -> Code Style -> Formatter.
If you are trying to format XML: Goto Window -> Preferences -> XML -> XML Files -> Editor and change Line width field.
You must have to create your own profile
In eclipse Window-> preferences -> Java -> Code Style -> Formatter, edit the profile. Under the Line Wrapping tab there is the option for line width (Maximum line width)
In preferences Java -> Code Style -> Formatter, if you don't have your own existing profile then create new with Eclipse[built-in] or select and edit the profile. Under the Line Wrapping tab is the option for line width (Maximum line width:).
