Fitting an internal door, how big a gap should be left at the bottom?

aliasojo

As title really. Joiner has put in new framing for an internal door but I think it's a little high and there will be too big a gap at the bottom once he hangs the door.

Assuming bare floorboards, in mm, how much of a gap should there be from floor to bottom of door?

What is the thickness of the floor finish?

Usually 20mm for carpeting.

Uncertain. It hasn't been picked yet but it will be a fairly flat short pile carpet.

Standard new Door Linings are 20mm longer than the door to allow for the flooring. laminate or carpet should fit under the door with out the need for trimming the under side of the door.
