Sizing is UNISEX and runs truer to MENs. Exact width (measured at bottom of garment) and length (measured from top of sleeve seam to bottom of garment) are as follows:
3X Large: 27" wide x 29" long
XX Large: 26" wide x 29" long
X Large: 24" wide x 28" long
Large: 24" wide x 26.5" long
Medium: 23.5" wide x and 26.5" long
Small: 22" wide x 25.5" long
