The belt of most of our structured baby carriers can be adjusted to go from 68cm (27,75 in.) to 165cm (65 in). An extension can be specially-made if this isn't long enough. The shoulder straps can also be lengthened to accommodate your needs. The belts of the Mei Tai and PöpNgo can fit waists from 55 (21.5 in) to 155 cm (61 in). Our stretchy wrap and Ring Sling Air-O are made longer by default and will accomodate all sizes, whereas our Snüg, woven Ring slings come in two sizes. For the ideal woven baby wrap size, please refer to their size chart
