A pant type disposable absorbent article comprising a front body panel, a back body panel positioned at a distance from said front body panel, and an absorbent member being attached to and bridging said front body panel and said back body panel; said absorbent article having a longitudinal central axis X-X and a transverse central axis Y-Y; said front body panel being substantially rectangular, and having a front waist edge, two front side edges, and an inward edge comprising a front crotch edge and leg opening edges on each side of the front crotch edge, between the front crotch edge and each side edge, said front body panel being at least partially elasticized, said back body panel having a rear waist edge, two back side edges, a back crotch edge, and leg opening edges on each side of the back crotch edge, between the back crotch edge and each of the back side edges, wherein the back crotch edge is a first distance from the rear waist edge, for each of the back side edges, a first end point of each of the back side edges is a second distance from a second end point, at an opposite end of each of the back side edges, wherein the first distance is greater than the second distance; said back body panel being at least partially elasticized; the front side edges of the front body panel being joined to the corresponding rear side edges of the back body panel; said absorbent member having a substantially rectangular shape, and comprising a liquid permeable top sheet layer, an absorbent body and a liquid impermeable back sheet layer; and comprising a front attachment portion being attached to the front body panel, a back attachment portion being attached to the back body panel, and an intermediate crotch portion extending from the front crotch edge of the inward edge of the front body panel to the back crotch edge of the back body panel; wherein the absorbent body has a total length L3, the front attachment portion has a length L4, the back attachment portion has a length L5, and the intermediate crotch portion has a length L6, said lengths L3, L4, L5, and L6 being taken in the longitudinal direction of the absorbent article; and the ratio of the length L6 of the intermediate crotch portion to the total length L3 of the absorbent body is L6:L3=1:2.4 to 1:3.5; and the ratio of the length L4 of the front attachment portion to the length L5 of said back attachment portion is L4:L5=1:1.4 to 1:2.5, wherein an imaginary center line coinciding with the transverse central axis Y-Y divides the absorbent article in two parts of equal longitudinal length, wherein the imaginary center line divides the intermediate crotch, portion of the absorbent member into a front crotch portion located between the imaginary center line and the front crotch edge of the front body panel, and a back crotch portion between the imaginary center line and the back crotch edge of the back body panel, wherein: the front portion has a length L1, and the back portion has a length L2, and wherein the ratio of the length L2 of the back portion to the length L1 of the front portion is L2:L1<0.4, or the back crotch edge of the back body panel is located in front of the imaginary center line, and wherein back leg elastics are arranged along the leg opening edges on each side of the back crotch edge.
