What wrap size should I purchase? I am 5 feet tall with an average body built.

I'm no expert of woven wrapping as I prefer hybrids and SSC but this might be of help. According to what I've read, size will depend on several things: 1) your size 2) your baby's size 3) the carries you want to do 4) and how well you tighten your wrap. Kindly refer to this photo I got from wrapevermore.com
