Main Entry: rule of thumb
1 : a method of procedure based on experience and common sense
2 : a general principle regarded as roughly correct but not intended to be scientifically accurate
**
I believe this refers to the size of the branch/twig/stick that a man was allowed to use beating his wife and children. The rule was that the branch/twig/stick not be thicker than the mans thumb.

It refers to applying something as a convenient general rule --not always exactly right, but pretty close. From this it is extended to refer to a rule based on experience and common sense which generally gives the right (or acceptable) answer.
For the dictionary definition see:
http://dictionary.reference.com/search?q=rule+of+thumb
As for the origins of the phrase. "Rule of thumb" refer to using the thumb as a quick means to measure something, generally for an inch since the adult thumb is approximately an inch wide. "Rule" here does NOT refer to a law or principle, but is an alternate form of the word "ruler" - a device used for MEASURING length, width... First attested use - 1692.
Also, the explanation that relates it to the width of a stick one could use to beat one's wife with (according to Common Law)? Total baloney -- there has never been such a rule. It's an urban legend that has most likely become popular in recent times because of its use by feminists.

It means, "BASIC RULE".
Example: The rule of thumb in economics is to make more money.
The LITERAL "RULE OF THUMB" is quite different. It's the old law stating that if you use a stick that is as thick, or less thick as your thumb, it is legal to beat your wife with.
The LITERAL term has been thrown aside a long time ago though.

It means 'as a general rule', it's origins were from the days when married men could legally hit their wives as long as the stick was no thicker than their thumb.

It's a rule coming from the experience.
Whatever you learn by yourself.
