This review is from: Pearl iZUMi Men's Quest Cycling Short (Sports Apparel)
My Perl Izumi shorts measure 16x6 inches giving lots of protection over a wide area. The padding goes down your leg a bit thus preventing pinching of sensitive structures that occurs with narrow padding. I bought a pair of tri shorts measuring 10x2.5 inches which begin to pinch after an hour or two. Small areas may work well for sprint triathelons but if you plan on hours of cycling then the larger size seems necessary.
