How Many spaces auto-indent do you use when you code?

Having an on-going argument/discussion with my boss about indentation. He’s from the 2 characters school of thought, whereas me and the other devs seem to favour 4 (normal default on most editors I think).

I say 4 is more readable, and you can trace bracket indents more easily at a glance for conditionals, but what does everyone else use?

cheers!

PS - Results will hopefully be used to make fun should they reflect my own personal opinion. If not thanks for posting anyway! :wink:
