Inseam

Im trying to order these trousers from a site online but am having a hard time deciding a size considering im an in-between and every store size varies, some run larger than others. The sizing chart mentions something about an inseam, basically the criteria for choosing your correct size, but I have no idea what that is… anyone care to clarify for me?

Re: Inseam

inseam is from the crotch area to the bottom of your leg. check this pic http://www.kohlscorporation.com/ecom/valueadded/productguides/media/images/SizeCharts/ManMeasurements.gif
