Rule of thumb

A rule of thumb is a general guideline or basic principle that people use based on experience, not an exact rule or law.

The origin of the phrase likely comes from using the thumb as a quick measuring tool (about an inch wide)

“As a rule of thumb, if pasta sticks to the wall, it’s done cooking.”
