Tip: Head and Hat Measurements

After posting the pattern for the Owl Hat I have received numerous comments on here and Ravelry asking how to make one in a larger size. So this has given me the idea to offer a tip on how to help with this dilemma.

I had already given the hat away as a gift so I couldn't expand on the size. I didn't even have the gauge to post. A comment from AbyBay prompted me to search out a chart with hat/ head sizes. AbyBay generously offered to send me a chart that she uses.

The chart does not tell you how many stitches or rounds to crochet but it will give you a general idea about how large you should make the hat.

So now when making a hat, no matter how loosely or tightly you crochet, or how bad you blow the gauge...you can still come up with the right size hat.

I found a great chart here
It is the most detailed chart that I've seen. I think it's my favorite.

I found the chart below on Crochet Geek here, and here it is:

Newborn

Head Circumference 13" - 14 "

Hat Circumference = 11.5" - 13"

Hat height = 5.5 to 6"

3 to 6 months

Head Circumference: 14" - 17 "

Hat height= 6.5 - 7"

6 to 12 months

Head Circumference: 16" - 19 "

Hat height = 7.5"

Toddler -12 months - 3 years

Hat height = 8"

Head Circumference: 18" to 20 "

Child - 3 - 10 years

Hat height =8.5"

Head Circumference: 19" - 20 1/2"

Teens

Hat height 9-10"

Head Circumference: 20 1/2" - 22"

Adult Woman

Head Circumference: 21.5" - 22.5"

Adult Man

Head Circumference: 23" - 24"

Edit: I found another chart here at Woolly Wormhead (mostly about knitted hats) that I am currently using. I really like this one, but the measurements are slightly different from the other one I found. Probably due to the differences in stretch between knit and crochet. Try both and see which you prefer
