How tight is hand tight?

[slappy]

I changed my oil and filter yesterday and was just wondering how do you know the oil filter is on tight enough when you just do it up hand tight. How tight is it meant to be? What I consider hand tight is going to be different from other people. I am always slightly paranoid afterwards that it is too loose and will lose oil or that it is too tight and has deformed and will leak. I use work gloves that give a good grip,any one else have any other method that they use?
