Within no more than 30 centimeters.
From the Calfornia DMV web page on parking: When you park alongside a curb on a level street, the front and back wheels must be parallel and within 18 inches of the curb. Park parallel to the street if there is no curb.
18 inches
When you do parallel parking you must align the wheels strictly parallel to the curb, and then shut the engine off.
MARYLAND DRIVER'S HANDBOOK Parallel Parking When parking on a two-way roadway, you must park parallel to and within 12 inches of the curb or the edge of the roadway. When you take the test for your driver's license, you will have to show the examiner that you can park in a parallel parking space 6 feet wide and 25 feet long. This is a timed exercise.
Palmdale, CA says you need to be within a foot and a half (18")22502(a) CVC - Curb Parking. Every vehicle parked at a curb where two-way traffic is permitted must be stopped or parked with the right hand wheels parallel to and within 18 inches of the curb. Where no curbs are present, right hand parallel parking is required, unless otherwise indicated by signs or other markings. Prohibited would be parking with the LEFT side wheels to the curb or parking at an angle to the roadway on the unpaved shoulder of a street.I presume it is the same for most places in California.

If you refer to the parallel parking part of the "skills" test...it is 25' long and six feet deep. To pass, you have to park within 18" of the "curb." a former WV DMV troop.
I think that would depend on the county and country in question. In the UK, "next to is next to" and you get a ticket.
