If you kneel on the floor and straighten your back (so you're "straight up" with your knees on the floor) and the bottom selvedge of the kilt is touching the floor, move the waistband up a bit.

Top of the kneecap is where you want it, or maybe half-an-inch higher than that.

You don't want it completely covering your kneecap. That'd be what J. Charles Thompson (author of "So You're Going to Wear the Kilt") calls the "trollopy" look.
