The pattern is here http://www.needlebeetle.com/free/seacap.htm
this pattern states both the size of head it will fit, AND the hat's finished size.
To fit head sizes: Small(Medium,Large), 19-20(21-22,23-24)”
Finished measurements:Circumference 18(19.25,20.5)”
If you need the hat to fit a head that is 21.5 inches, Knit the medium.
