Crochet Ear Warmer Size Chart with a Single Crochet Ear Warmer Pattern
Below is my single crochet ear warmer pattern with an ear warmers size chart to help take the guesswork out when making changes to my ear warmer or headband patterns. It is super easy to take any pattern and make it your size when you have a stitch multiple, which I generally provide in my crochet patterns.
The crochet ear warmer is beginner-friendly, and also includes a short video at the end of the written pattern.

Not only is this size chart great for ear warmers, but can also be used for making crochet headbands. For headbands, all you need to know is the circumference, as the width of the band doesn’t really matter.
Crochet ear warmers are the perfect accessory to keep your ears and forehead cozy in the spring and fall weather. And in the cold winter months, they are an alternative to winter hats, and can be worn comfortably underneath the hood of a jacket. Regardless of how you like to wear them, they do the job nicely for keeping your ears toasty.
You can even take any ear warmer and turn it into a comfortable headband to hold your hair back on a windy day.
Regardless of how wide you choose to make them, they make for great gift ideas, and also for selling at craft fairs.

How Wide Should a Crochet Ear Warmer Be?
Ear warmers don’t have to be very wide as you only need them to be slightly wider than your ears. With that said, I find that when they are a bit wider than the ears, they tend to stay on a bit better, making them a bit more comfortable to wear.
Baby. 2″ wide.
Toddler. 3″ wide.
Children. 3-3.5″ wide.
Adults. 3.5-5″ wide.
With that said, depending on the stitch pattern, you can reduce the width to any width you like and wear the band as a headband.

How Long Should an Ear Warmer Be
Ear warmers should be at a negative ease for a comfortable fit. This means that they are about one to two, and in some cases even three inches smaller than the head circumference.
So the first thing you want to do is to take measurement of the head circumference. Then subtract the amount of ease to get the final circumference that you need.
If you’re planning on making multiple bands in different sizes, taking the time to do a gauge swatch can be a huge time saver in the end!
For children and adults, the general rule is about a 2 inch negative ease.
For a toddler size, you could go between 1-2″ of negative ease.
For babies the general rule is a 1 inch negative ease, or even less. You might even choose to make them the exact measurement than the head measurement. Their tiny heads are fragile, so you don’t want anything too tight around their heads. Plus, the circumference of a baby headband is significantly shorter than an adult size. Which means that the overall stretch in a baby band will also be less!
The more stretch that you have in the band, the more negative ease you can add. Things that affect the amount of stretch are the yarn and stitch pattern. Using a larger hook with a thinner yarn can also give you more stretch.
The more stretch you have, the more comfort you’ll have as you wear it. It’ll stay on better and won’t feel as tight.
Stretchy yarn, like Vanna’s Choice will give you a good amount of stretch of the finished band. It is a worsted weight yarn and can be worked with an I or a J crochet hook to give you loads of stretch.
A bulky weight yarn can be worked with an L or an N crochet hook to give you the stretch that you’re looking for.

Below is a general guideline for the length, or circumference, of an ear warmer. Everyone is a different size, so be sure to take measurements and give or take an inch from the following measurements.
Preemie 1 lb = 7″
Preemie 2 lb = 8″
Preemie 3 lb = 9″
Preemie 4 lb = 10″
Preemie 5 lb = 11″
Preemie 6 lb = 12″
Newborn = 13″
1-3 Months = 14″
3-6 Months = 15″
6-12 Months = 16″
1-2 Years = 16.5″
3-5 Years = 17″
6-9 Years = 18″
Teen/Adult Small = 19″
Adult Medium = 20″
Adult Large = 21″
Adult X-Large = 22″
How Much Yarn is Needed for an Ear Warmer
You really don’t need much yarn to make an ear warmer, thus making it a great project idea for cleaning up your yarn stash. One skein or less is usually all you need, depending on the size of the skein and the band.
It all depends on the stitch pattern and the thickness of the yarn. But 100 to 200 yards is usually a generous amount to complete one band.
Ear Warmer Size Chart by Age
This size chart gives you the general measurements for ear warmer measurements from micro preemie sizes to adult extra large! I’ve listed the sizes by age, to make it easy for you to reference.
Remember though, this is a general guideline, so you may need to add or subtract an inch from the circumference measurements.
