1. An absorbent article comprising an absorbent core sandwiched between a topsheet and a backsheet, said article being arranged along a longitudinal axis and a transversal axis extending in a perpendicular direction in relation to the longitudinal axis and said article defining a front portion, a back portion and a crotch portion,
wherein said absorbent core further comprises an absorbent component enclosed by a core cover comprising an upper side and a lower side,
wherein the absorbent core is formed with a sealing arrangement for joining said upper and lower sides comprising two channel sealings extending along said longitudinal axis in said crotch portion and defining a channel sealing width,
wherein the channel sealings are positioned within respective channels extending along said longitudinal axis in said absorbent core, which channels are free of said absorbent component, and wherein an entirety of each of the channels extends straight and generally parallel to the longitudinal axis, and define a center segment having a center segment width and parallel side segments having a side segment width, of the absorbent core,
wherein the absorbent article further comprises at least one wetness indicator being positioned only in said front portion, only in said back portion, or in both the front portion and the back portion;
wherein said wetness indicator is arranged so that the wetness indicator does not extend between, in a direction of the transverse axis, the two channel sealings in the absorbent core,
wherein said wetness indicator is arranged to overlap with the absorbent core;
wherein the center segment width is greater than the side segment width; and
a width of the absorbent component in the center segment between the channel sealings is a first width and a distance between the channel sealings is a third width, and a ratio of the first width over the third width is greater than 0.75;
wherein the parallel side segments each has a second width and are defined in the absorbent component outside each channel sealing; and
wherein the absorbent article is configured so that 33-41% by weight of the total amount of absorbent material in the crotch region is located in the centre segment and 25-33% by weight of the total absorbent material in the crotch region is located in each one of the side segments.
