rule-of-thumb

Rough working principle

A rule-of-thumb is a practical guideline based on experience rather than precise measurement or theory: As a rule of thumb, plan for one bottle of wine per guest.

The phrase suggests useful approximation—good enough for everyday purposes, though not exact.

Rules-of-thumb help navigate situations where strict calculation would be impractical or unnecessary.
