I just guestimated what I wanted to cook, two buts. I think my distances are from the steamer wring to the 2nd rack 5" from the second rack to the top 4-5". The third rack sits almost flush with the top, and that gives me about 2-3" of clearance under the lid.
One thing you need to know regarding three levels is that the top mounted screws will need to be shorter than bottom mounted screws. Otherwise you will have an issue putting in the racks.
