It is subjective, but I usually wrap if there is anything important in the line after about 120 characters. Basically, if you have to scroll your editor window to see something important, the line is too long. I use 120 characters because that's a good limit for coding on a laptop, GitHub, etc., plus anything too wide is just hard to read even if you have a huge screen.

Also, besides just wrapping, it's often better to shorten the code by introducing a variable or helper method, static import something, etc.
