Pleat depth spacing preferences?

[Eric T]

I'm looking to make my first kilt, and wondered what are people's advice for pleat depth and spacing, and what is most functional with a 2 inch spacing, 3 inches deep or maybe 4? And what is best for closer spacing? I know a certain amount is needed so the kilt doesn't ride up when legs are spread one way or another, and there may be other reasons. And what about fabric weight and pleat spacing, depth and number of pleats: is there a better depth/number for ligher or heavier fabrics? I aim to do sewn knife-edged pleats on a semi-trad/semi-modern design of my own. Your insights and experience is much appreciated. (I forgot to mention when I first posted this that I will not be using a tartan fabric, but rather solid or other print or stripe. My apologies to first two responses.)

May 15: Also, what's the best plan for the reverse pleats. I've heard also that some put them at both sides, some at just the under apron side. How deep should they be?
