I measure my kids for their slings the same way I measure myself/friends for slings (unpadded ring slings). For the length of the sling I measure from shoulder to hip, back up to shoulder and down to desired length of tail. For the width of the sling I measure from the collarbone to the hip adding a couple inches for child and 6-8 for adult.
Hope that made sense!
