How to measure hat size


  • Grab a 25-inch piece of string, a ruler, and a measuring tape first. Use these three easy actions once you have everything you need.

  • How big your head is. Use a measuring tape or piece of twine to evenly wrap them around your head until they overlap. Hold it about an inch over your ears for the most precise measurement.

  • Select your size: Once you've established the circumference of your head, grab a measuring tape or piece of string and record the length on a ruler.

  • Determine your size by measuring with a ruler and then looking up your size in the table. Inches and centimeters are frequently used in these tables to list measures. The average adult hat size is 53 to 58 centimeters.


If your measurements fall between two sizes, we suggest going up to the next size, measured to the nearest 1/8 inch. The size can then be altered, if necessary, using the hat's measuring tape.

Even though there is an industry standard, it's important to remember that each hat manufacturer has its own distinctive style. Depending on the manufacturer, the hat's sizing may vary and be inconsistent. It's important to take a head measurement and refer to the particular hat size chart.

You must first realize that there are three standard sizes for hats before you can choose the appropriate one for you:

The most commonly used sizes you will see here are SM, MD, LG, XL, and sometimes 2 and 3X sizes.

The second most common size we have on our website is the half size. This means that there are usually only two sizes: SM/MD and LG/XL. Sizes 2X are sometimes available.

The more traditional size is the exact size in inches and/or centimeters. You will usually see these sizes on more expensive hats.

Women's sizes

When choosing a size, remember that men's and women's hats differ from one another. Women's hats are normally made in a single location. In general, a women's hat can easily fit a woman with a head circumference of 21 1/2 inches to 22 1/4 inches.

Women's hats don't have a standard size, so various makers may utilize different sizes. The formula for one brand might not work for another. The best way to avoid this issue is to measure the circumference of your head and compare it to the specifications listed by the manufacturer for each hat you are thinking about buying.

Men's sizes

Men's hats frequently come in a limited range of sizes. Men's hat sizes can be expressed numerically or with measurements ranging from S to XL. In addition to being available in one size to fit most possibilities, men's hats typically have a wider size variety than do those for women.

After taking a measurement of your head, consult the manufacturer's sizing chart to decide which size to order. Compare the hat sizes with your own if you are thinking about a hat that is advertised as fitting the best. It's a good idea to see if the hat has features like an adjustable band that lets you change the size as well.

Tips and tricks for measuring your hat size:

  1. Measure twice, buy once

The proverbial "old carpenter's proverb" also applies to measuring hats. Especially if you're measuring your head for the first time, it can be dangerous to utilize the first measurement you take. You can get a hat that is unpleasant if you order one using the wrong measurements. Try to measure at least twice before ordering to avoid this issue.

Record the circumference in both centimeters and inches after the initial measurement. the second time, measure You are most likely on the right path if you acquire the same measurement twice. Measure a third time if the results are different from the first. The idea is to consistently receive the same numbers, so you know what you're buying. The goal is to get the same numbers every time, so you can be sure you're buying the right hat.

  1. Size up, not down

If you are measuring your head and the result is between the numbers, it is recommended that you round up to the next 1/8 inch. It may not seem like much, but every fraction of an inch can make a big difference when it comes to a comfortable hat.

  1. Don't tighten the string too tight

Don't pull the string or flexible measuring tape too tightly after you've wrapped it around your head if you're using it to take measurements. While you don't want it to hang down, you also don't want to pull too hard because that will modify your measurements and give you the incorrect size.

As a general rule, pull the string as tight as you would like the hat to feel while it is on your head. Be mindful of how tightly you are pulling on the rope because some hats require more room than others.

  1. Expect differences between manufacturers

Unfortunately, while there is an industry standard for headgear sizes, there are manufacturing inconsistencies and differences between suppliers. That's why it's always important to measure and refer to the seller's size chart before buying a hat.

  1. The size depends on the style you choose

Certain styles of headwear are meant to be worn in different ways. Some hats should fit snugly around the head, while others should be slightly loose. Consider the fit and feel of the hat when you are looking at what size to order. In some cases, this may mean that the size is slightly different from the measurements you took.
