Jack, I don't follow that. I believe that it's true for a box-pleat, or a box pleat of the "standard" regular sort; but the knife pleat is much more flexible.

Normally, it would work out

depth = 1/2 (sett - reveal)

where depth and reveal are not necessarily equal. In practice, a little length goes into the folds, I think --- I am not an expert, nor do I play one on the 'net. I just like algebra.

I'm looking at a practice kilt with sett 5 inches plus, depth 4-1/2", reveal just short of 1 inch. (double sett per pleat)
