Hat Size Guide: How do I measure my head size?

Measuring Your Head

Knowing your exact head measurement and your desired fit is all we need to make a perfectly fitting hat for you.

To determine your head measurement, you will need a sewing measuring tape. Wrap your tape gently around where you wish your hat to rest. Do not pull the tape too tightly unless you want your hat to be as tight.

A tight-fitting hat wears higher and stays on better on a windy day. It could feel a bit uncomfortable, though, during a long stroll on a hot sunny day. A looser-fitting hat, on the other hand, is far more comfortable, but your hat will wear a bit lower.

Your Frequently Asked Hat Sizing Questions Answered

How can I determine my head shape for a better hat fit?

Typically, if you find that a hat presses or feels tight on your forehead and at the back of your head, but you notice a gap or space above your ears, it's an indication that you might have a "long oval" head shape. On the other hand, if a hat fits snugly all around without any noticeable gaps, you likely have a "regular oval" head shape.

Can I provide measurements to ensure the best hat fit for my head shape?

Can I provide measurements to ensure the best hat fit for my head shape?

I have a very large/small head. Can I still order a custom hat?

Absolutely! We pride ourselves on offering a wide range of sizes. Please contact our customer service for more information on ordering a hat outside of our standard sizes.

I have a hat that fits me perfectly. Can I use that for sizing?

Unfortunately, it's not accurate to use the size of another hat for sizing without a special instrument called a measuring ring. The most reliable way to find your size is to measure your head's circumference using a flexible measuring tape. If you're still unsure about your size, don't hesitate to reach out to our customer service team for help.

I’m buying a hat as a gift, but I don’t know the recipient's hat size. What should I do?

If you're unsure about the size, consider our gift cards. This way, the recipient can measure their own size and select their preferred style.

How often should I measure my head? Does my hat size change?

Generally, adult head sizes do not change. However, changes in weight, hairstyles, and age can result in minor changes. If you haven't measured your head in a while, it might be a good idea to do so before ordering your next hat.

What if I'm in between sizes? Should I size up or down?

If your measurements fall in between two sizes, we generally recommend going for the larger size. A slightly larger hat will be more comfortable and can be adjusted for a better fit.

Do you offer custom sizing?

Yes, we do offer custom sizing for customers who do not fit within our standard size range. Please contact our customer service team for more information.

Do all hat styles come in all sizes?

Most of our hat styles are available in a wide range of sizes. However, there may be some exceptions due to the design or materials of the hat. Please check the product details for each hat.

Are the sizes the same for men and women?

Yes, hat sizes are unisex and are based on the circumference of your head. However, the style and fit of certain hats may be designed with a specific gender in mind.

I have thick hair. Should I order a larger size to accommodate it?

If you have thick or voluminous hair, you may want to consider ordering a slightly larger size. However, each individual is different, so it's best to take a measurement with your typical hairstyle to be sure.
