The range varies from under 100 feet to global coverage based on exactly which radio you have, the conditions at the time of transmission and other factors.  Though it should be noted that most consumer models that require no use of a amateur radio license  aka HAM Radio License have very limited ranges.  Packaging will often claim ranges of 12-30 or more miles.  This range can't be expected and is based on a best case scenario of topography and other conditions.  Most such radios have a real world range of only 1/2 - miles, regardless of packaging claims.
