Hat Sizes Reference Guide

Crocheters are always asking for hat sizing requirements for the human body. What are the typical dimensions for the average person?

For example, we are often asked about getting the right sizes for children when a crocheter gives us an age. If you look at a classroom in school, kids don’t grow evenly in both height and body shape. Us adults, we too are different shapes and sizes.

Our Jeanne has taken the time to research general sizes for heads when it comes to hats. She has given the standards of typical sizes that the textile industry uses for the sizing across the spectrum. More importantly, she has given the dimensions of the age bracket to give crocheters a better understanding on what size patterns they should be looking at. In the olden days, I raised a young man that had an exceptionally large head for his age. He eventually grew into his head but at the time of childhood, he would have fit into an adult hat and not a kids hat.

If you take some measurements of the person you are making your hat for, you may find they are not within the typical standard textile industry. Knowing this information, it will allow you to adjust your pattern to the correct sizes so you are not crocheting something that ends up too big or too small.

Here are a few photo examples of how to use these charts.

When you start a beanie style hat, meaning from the top down, the first measurement you need to know is what size head is this going to fit.  Take the tape measure and go around the head at the point around the forehead for the Head Measurement.

If measuring the person beforehand is not possible, try ‘guestimating’ using the chart by age.

The next measurement is the Hat Crown Size.  You want to measure your circle across and use the chart to determine when to stop increasing your circle and then start to work even.

    I need to ask…do these hat sizes refer to unstretched hats? I’m not good at hats.

    Thank you

    • Jeanne is unavailable today. I’ll ask her to respond possibly tomorrow.

      • Octavia

        I wanted to thank you for the tips. I’m making hats for men and want to size them correctly. I’m making them flat and then joining at the back. I’m sure your tips will help me:)

  2. Memith

    Thank you so much! This is exactly what I needed! I’m making hats for my 10 year old grand niece in Idaho and I have no way of measuring her. Thank you Jeanne. I love the Crochet Crowd!

  4. Kimberly Catlin

    If the crown diameter measure is correct as for example 6.05 inch which basically circumference would be 19 inch then end up measure 21 inch of circumference so what would you do? Even crown diameter is correctly read but not circumference after finish crochet hat.. I notice people don’t count circumference after finish measure hat but notice people count it as crown diameter more than circumference hat..

    Please help..

  5. Sarah Moulding

    If you start at the brim rather than the top, would the head circumference be the actual size you would make it?

  6. Thanks, it was filled with lots of helpful tips.

  7. Carol

    Thank you. Thank you. I donate most of my hats and scarfs and I can’t tell them who it will fit (unless it’s obvious). This will help me a lot!!

  8. Loved this. Been looking for something exactly like this. Thanks so much

  9. Nicole

    Will use the charts and all your tricks … Thank you

  10. Teresa Ballantyne

    Thank you, for all the future hats I will make that will fit! Every hat I make ends up going to someone other than the person it was made for. And, our family is one where everybody’s head is oversized. Now I know how to measure those noggins!

  11. Shannon Vary
