Unstretched, this hat measures 18 inches in circumference. It fits nicely over my 2.5 year olds afro, lol. It was originally intended to be a slouchy, but because of my daughter’s hair it fits more like a Beanie. To make it slouchier you can add a few extra Rounds of clusters. As written, this pattern takes up almost exactly 1 skein of yarn, so if you make it longer you will have to make sure you purchase 2 skeins of the suggested yarn.
