Ideally you should be as close as possible to the curb when you finish parking, just to lessen the chances that your car won't accidentally get hit or scraped by cars driving too close to you on the side of the road. However, 12-18 inches is usually a safe distance away from the curb.

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.

I don't know how much it varies from state to state but it was "within 6 inches" when I took my test many years ago.
A no parking sign typically extends about 18 inches from the curb or edge of the road.
Yes, you can be ticketed for parking too far from the curb. Most jurisdictions have specific regulations that require vehicles to be parked within a certain distance of the curb, typically no more than 12 inches. Failure to comply with this rule can lead to receiving a parking citation. It's important to check local parking laws, as they may vary by location.
About 10-16 inches.
Apparently it's 18 inches in most places.
The distance is likely to be different depending on what State you live in. Where I work, in the State of Washington, the front wheels must be within 12 inches of the curb, and if on a hill, the front wheels must be turned in.
A parked car should not protrude into the traffic lane at all. Get your wheels within 6 inches of the curb and you'll be out of the traffic lane. If you have an oversized vehicle, find off-street parking.
