I knit to a circumference 1-3" smaller than head measurement. I often knit a child size for my 20" head. Finished hat circumference that fits me, unstretched is 17-18" . Thanks, Tracy MacFarlane !
Head Circumference Chart | Welcome to the Craft Yarn Council For an accurate head measure, place a tape measure across the forehead and measure around the full circumference of the head. Keep the tape snug for accurate results.craftyarncouncil.com red and gold prom dresses
