Aaron Marino of alpha m. discusses the pant rise which is the distance between the waist band to the bottom of the crotch.
A standard rise is about 12 inches. 'Standard' was standard back in the 50's and 60's, which they wore their pants at their belly button. We currently wear pants around our natural waist.
Designers are now making low and mid rises (8 to 11 inches) making the pant fit better without all the extra fabric of 12 inch rise. Look into a lower rise pant so your crotch isn't baggy.
