Head/hat Size Chart - knitted or crocheted hats

Head/hat Size Chart - knitted or crocheted hats should be made about 1- 1 1/2" smaller around than the head circumference, as the hats should stretch and sizes are not an exact science! If you make it, someone will fit into it. =) IMPORTANT! * Height given here is measured BEFORE you turn the brim up - from the bottom of the hat to the center top of hat. (This is NOT the actual height of the head as measurements assume you will be turning up a brim.) Hats can be made taller if you want a larger brim to fold up. On newborn hats I plan to fold up about 1" for a brim, on adult hats I usually figure 2" - 3" or so for a brim, but this varies according to personal preference.
