How to Read a Chart

Most hat size charts include several columns: age/size, crown measurement, brim measurement, and height measurement.

To get the most accurate fit, measure the wearer’s head before starting your project. If you are unable to measure, a standard measurement usually works fine.

Age/Size

While most people’s heads vary in size widely, even across age groups, the flexibility of crocheted fabric makes it possible to standardize a chart in an age/size that will fit most people.

Find the size or age needed, then check across the row to find the correct measurements required to create the size.

Crown Measurement

The crown measurement is only included on hats made from the top down. Ideally, the hat’s crown will fit very closely to the head.

If the wearer has full hair or wants a slouchy fit, you may want to size up a little.

Brim Length Measurement

The brim length measurement is only included on hats made from the bottom up.

You will want the brim to be 1″-2″ smaller than the wearer’s head for a snug fit.

Some charts will list the exact measurement to make the brim, while others will list the usual size of the person’s head. Always double-check which measurement is given.

Hat Length Measurement

The hat length is the most customizable part of a crocheted hat. If you make the hat extra long from the top down, you can fold up the bottom to make a cozy, double-layered brim.

If you add length working from the bottom to the top, you will create a loose, slouchy hat instead of a fitted beanie.

Crochet Hat Size Chart by Age

This crochet hat size chart includes all sizes by age from preemie baby to adult large. It includes three hat lengths to help you adjust crochet hat sizes from caps to beanies and slouchy hats. Also included in this chart are the head circumference, the hat circumference, and crown diameter to help you crochet top-down hats as well as bottom up hats.

It is always best to take exact measurements of the person you are making hats for, but when that’s not possible, this hat sizing guide can come in handy.

Important Measurements

There are three essential measurements to pay attention to when making a hat: the crown, the height, and the brim length.

The Crown

The crown of the hat is the part that covers the very top of the wearer’s head. This measurement is most important when making a top-down hat.

The Height

The height of the hat measures from the bottom of the brim to the crown. Depending on the desired fit, the brim might fall at the top, middle, or bottom of the ear.

The Brim Length

The brim length of the hat should be roughly 1″ smaller than the total circumference of the wearer’s head.

Because most yarns have a certain amount of stretch, the smaller brim will fit snugly and stay in place. This measurement is most important for bottom-up hats.
