1. A wearable article continuous in a longitudinal direction and a transverse direction comprising a front elastic belt region, a back elastic belt region, a crotch region, a waist opening and two leg openings; the crotch region extending longitudinally between the front elastic belt region and the back elastic belt region;
the front elastic belt region having an area of A1, the crotch region having an area of A2, the back elastic belt region having an area of A3, the front elastic belt region having a front placement distance L8, and the back elastic belt region having a back placement distance L9 according to the measurements herein;
wherein the total of A1, A2 and A3 is from about 1250 cm2 to about 1400 cm2, and having a relationship of A3>A1>A2; and
wherein the ratio of L8 to L9 is no more than about 0.8;
wherein the article is formed of a center chassis and a ring-like elastic belt comprising the front elastic belt region and the back elastic belt region; the center of the front elastic belt region is joined to a front waist panel of the center chassis, the center of the back elastic belt region is joined to a back waist panel of the center chassis, the front and back elastic belt regions each having a left side panel and a right side panel where the central chassis does not overlap, wherein the front and back elastic regions each are a laminate of an inner sheet, an outer sheet, and a plurality of elastic strands sandwiched therebetween, wherein all of the elastic strands sandwiched between the inner sheet and the outer sheet run in the transverse direction substantially parallel to each other;
the entirety of the length of the belt side edge of the front elastic belt region is seamed with a certain length of the belt side edge of the back elastic belt region to define a seam length L5;
the front belt region divided into 4 zones extending in the transverse direction and defined by its location from the distal edge to the proximal edge relative to the percentage of the seam length L5 wherein; 0-30% is a waist zone, 30-50% is a distal tummy zone, 50-85% is a proximal tummy zone, and 85-100% is a leg zone;
the back elastic belt region divided into 3 zones extending in the transverse direction and defined by its location from the distal edge to the proximal edge relative to the percentage of the seam length L5 wherein; 0-30% is a waist zone, 30-75% is a tummy zone, and 75-100% is a leg zone; and
wherein the tensile stress of the back tummy zone is higher than the tensile stress of any other zone.
