Measurements for Designers: Hats

Print Friendly, PDF & Email

I love crochet hats. I love crochet everything, obviously, but hats are especially nice because they make a convenient handmade gift. They are quick to make, do not require a lot of materials, and work as a gift for both the males and females (and children!) in your life. As an added bonus, you don’t really need a pattern to make a hat. Just crochet a circle roughly the same circumference as the giftee’s head, then crochet evenly until the hat is as long as you’d like it to be.

But what if you don’t know the recipient’s head size and you want to surprise them? What if the recipient hasn’t been born yet? My friends, I have some measurements for you. These are general guidelines, of course; not every human fits in a standardized box. But these measurements will give you a rough idea of how big to make your hats in various sizes.
