An absorbent article has non-uniform dimensioned side barrier features and includes a lower structure. The lower structure includes a backsheet layer, a first fluid permeable topsheet layer bonded to the backsheet layer, and a first absorbent core layer sandwiched between the first topsheet layer and the backsheet layer, with the first absorbent core layer having lateral-most side edges. The article also includes an upper structure in fluid communication with the lower structure. The upper structure is adjacent and bonded to the lower structure at the first fluid permeable topsheet layer, and includes a second fluid permeable topsheet layer and at least one additional absorbent layer. The second topsheet layer is folded about the at least one additional layer to create substantially straight side barrier feature lateral-most edges with the lateral-most edges being either inboard of the lateral-most side edges of said first absorbent core layer or generally aligned along the depth direction with the lateral-most side edges of the first absorbent core layer. The upper structure is bonded to the lower structure at the lateral-most edges, at least at said article longitudinal ends. The upper structure includes embossment channels or embossment features concave or indented with respect to the side barrier feature lateral-most edges, and the embossment channels or embossment features are within at least two layers of said article. The embossment channels or embossment features and said side barrier feature lateral-most edges define side barrier features having either non-uniform lateral width dimensions, non-uniform height dimensions or a combination of non-uniform lateral width and non-uniform height dimensions along the longitudinal direction of said article.
