I wanted to share my chart for sizing crochet hats. I came up with this chart by researching average head sizes. Sizing crocheted hats is not an exact science, but maybe this will help you get started. Enjoy!

Thank you for putting in the crown size, your blog is the only place I've been able to find that. I had pretty much been guessing before. I am having some issues with using the crown size and the hand ending up much bigger than anticipated. One hat was using a very bulky yarn....maybe I should make the crown even smaller to compensate for this or do smaller crochet stitches for several rows?

I would just count your gauge in the last row. For example, if you are getting 2 sts per in and you want a 13" circumference hat, end your crown at 26 sts. It should work even if the crown measurement doesn't match your desired circumference. Sometimes certain yarns will continue to grow a little down the sides of the hat.

If you take an inch or two from the circumference of the head and divide that number by pi (3.14) you will get the estimated diameter of the hat you are making. You increase the crown until you get that measurement straight across and then you stop the increase and just keep the same amount of stitches each round of the hat. There are times, because of the give of the yarn, I have to decrease a stitch to have the hat keep the shape I am wanting.

Jessica, The number of rounds will depend upon your yarn and hook size. You increase until the desired crown size is achieved, then stop increasing. Continue to crochet rounds without increasing until the hat sides are the desired length.

Yes, thank you for the chart and the explanatiion about the crown and stitches per inch, etc. Like the other reader, I made a hat using the crown size for a 12 mth old and it would fit me, 47 years old. Frogged it. Teresa

When you say hat height is from crown to edge, are you measuring from the very top (center of the crown at the beginning) or are you measuring from the last row of increases? I use your chart almost daily!!! Thanks so much!

Jessica, When you crochet hats you usually start from the crown and work your way to the brim. Also all your rows are actually rounds so each row makes a circle. When I say top center I mean the center of the first round (remember it is a circle, so the inside center of that circle) which will be the crown of the hat.

I have a question about your hat heights. Where should these be hitting on a head? For instance, I'm an adult, I measure my head from crown to just below my ears and I get just under 8 1/2 inches and I measure most of the hats I've ever bought from like a ski shop and they are all around 8- 8 1/2 inches. Is that just a difference between maybe men and womens heads? Even though with the toddler sizes. My son is 14 months. His head is 90th percentile. I make a hat according this chart and it is very long on him and comes down over his eyes almost.

Shannon, I think it is just a matter of personal preference. The crown size of this chart is what is most important. Length will vary by hat style & the persons head shape. For instance, a rounder head will need more length than a hat for someone with a narrower head. Just adjust the length as needed.

Thanks so much! I am a tight crocheter so I always have to alter patterns and just had a pattern go wrong even with using their gauge! You're awesome for sharing!!!

I read somewhere to divide the finished hat circumference by pi (3.14) and that gives you how big the crown should be; at that point you crochet even until it is the correct height. It works very well for me.

When making a round back style bonnet, I can't seem to figure out how big the initial circle should be according to these charts, does anyone have or know of a chart for bonnet sizing?

I don't know of one, but you could use the same crown measurements. Once you get the crown size (which will be the rounded back of the bonnet) complete, you would join, and start another row working one st in each st of the previous row. Stop this row when you still have about an inch to 2 inches of sts left. Then you will turn and begin working back and forth until the top and sides of the bonnet are complete.

DeleteBut if im increasing a hat, til which round do i do it?? im confused..

Thanks so much for this chart! I've been looking everywhere for a chart like this that included the crown size! (:

ReplyDeleteYes. crown means the top center of the hat. Glad you find the chart helpful!

DeleteTop center?? how many rounds is that?

DeleteYou are my heroine! This is EXACTLY what I've been searching for! Thank you, thank you!

ReplyDeleteThank you so much for this chart! I've used it several times now, and my hats come out exactly the right size!

ReplyDeleteThis is a great chart! Thanks so much! :)

ReplyDeleteThank you so much! I am sure this will mean less frogging in mr future! Hurray!
