How much bottom clearance on an interior door?

My husband and I are debating what the standard clearance is for the bottom of an interior door--that is, how much of a gap should there be between the bottom of the door and the carpet? Is there a standard for this?

Thanks!

Enough so it doesn't drag the carpet, but not so much the kids can lay on the floor in the hall and spy on ya

Nah, I don't think there is any "standard".....if you have a forced air type system, it's probably better to have a little bigger gap so the air that enters the room register can get back to the cold air return when the door is closed so air ( and heat/cooling) will circulate in the room.

On a funnier note:

The doors in the dorm I where I went to college had about a 1" gap on the bottom of the door from the room into the hall. A favorite past time after midnite was to fill a LARGE envelope with shaving cream, seal it and cut one corner off. Slide about 1/4 of the envelope under the door using that nice gap, then stomp the heck out of it, blowing shaving cream all over the room and occupants inside ......yep, boys will be boys.....did I mention I got drafted after I flunked out of there ?....ahahahahaha......

SEE KIDS......YOU SHOULD "STUDY" WHEN YOU GET THERE !!!

and don't try this at home
