Interior door clearance...

What gap is typical for adequate air flow? I need to trim down a few interior doors. The first two are 36" wide for 100sf or so bedrooms with no individual returns. The master has double doors measuring 60" total with a return in the room. There is one large return in the hall near the two bedrooms. I'm thinking 3/8" for the small bedrooms and 1/8" for the master. Please let me know if this works. I want the heat pump to work as efficiently as possible.

I try to have a min. of 1/2. problum is if you have cheap hollow core door there's not much wood on the bottom.
Cut to much and your stuck having to dig out the old strip and glue it up inside the door.
