Hat Size Chart | How to Measure Hat Size

There's something about a stylish hat that fits someone's head perfectly that speaks volumes about a person's style and confidence.

However, most high-quality hats come in specific sizes, and it can be challenging to know which size is best for your head.

We put together this guide to teach you how to measure your head correctly and other tips to help you find the perfect style and size hat for your head.

How to Measure Your Head Size

A large part of finding the perfect hat is finding a hat that fits your head perfectly. A hat that fits properly can enhance the features of your face and compliment any outfit.

However, an ill-fitting hat might only make it out of your closet sometimes. The best-looking hat in the world can't be worn and enjoyed if it doesn't fit you properly and it slides all over your face.

Before buying a hat, you must measure the size of your head first. Unfortunately, even many hats labeled as one-size-fits-all don't always fit everyone. Hence, getting an accurate measure of your head first is essential, and then referring to the size chart below.

Steps for Measuring Your Head

You'll need a measuring tape or a long piece of string and a ruler to start. Then follow these three easy steps:

  1. Use the tape measure or piece of string to measure the circumference of your head by placing it just about an inch above your ears.
  2. If you're using a tape measure, record the measurement in inches and centimeters onto a piece of paper. If you're using a string, place the piece of string and measure it using your ruler, then record those measurements.
  3. Take the measurements and then compare them to the hat sizing chart of the manufacturer. We've added the one from American Hat Makers below for your reference.

Tips for Measuring Your Hat Size

It's not difficult to measure yourself to get your hat size, but you must do it correctly for your hat to fit properly.

Here are some additional tips to help guide you through the process.

Expect Differences in Sizes From Manufacturer to Manufacturer

While there is an industry standard for the size of hats, every manufacturer makes every hat in their own way, which can lead to slight variations in sizes.

These variations are why it's critical to get an accurate measurement of your head and then match it to the correct size on their specific size chart.

Measure Twice, Order Once

Use the same mantra carpenters use and measure twice before placing your order. Take your first measurement, record it in inches and centimeters, wait a few minutes and do it again.

Or, have someone else take a second measurement for you. Then, if the numbers don't match, take a third measurement to verify which is correct.

It's better to measure several times than order the wrong-sized hat.

Don't Pull the String/Measuring Tape Too Tightly

It might be tempting to pull too tightly to pull the measuring tape or string too tightly to get a measurement for a snug fit. Instead, pull the string or measuring tape so it's as tight as you'd want the hat to feel on your head.

It's also important to remember that some hats should fit more loosely than others, so think about the style of hat that you're looking at and how that should rest on your head.

When In Doubt, Go Up a Size

What do you do if you measure your head and your measurement comes up in-between sizes?

Because sizes are approximate and will vary with the style of the hat and the material it's made from, it's best to choose a larger than a smaller one.

Find the Right Hat Style for the Shape of Your Face

While it's essential to find the hat that fits your head, it's also important to look for one that accentuates the shape of your face.

Here are some recommendations for finding the right hat style for the shape of your face:

  • If you have a diamond-shaped face, look for hat styles that sit on the back of the head.
  • If you have a round face, look for hats with angled elements that reveal your face.
  • If you have a long face, look for wide-brim hats and brims that bisect the forehead.
  • Look for hats with a broader crown if you have a heart-shaped face.
  • Straight brims and floppy hats can be flattering if you have a square-shaped face.

However, these are only suggestions, not rules, so what's important is finding the hat that looks and feels like it was made specifically for you.

Measure Your Head Properly to Find the Perfect Fitting Hat

It doesn't take a lot of time or tools to measure your head correctly so you can find the perfect fitting hat for your head.

It only takes a measuring tape or some string and a ruler. Pull it snugly around your head about an inch above the ears. Of course, it's always a good idea to take a second measurement to confirm the first one.

Hat sizes differ from manufacturer to manufacturer, style to style, and according to the materials they are made with. If you're in between sizes, it's typically a good idea to go up a size. However, many hats, like those from American Hat Makers, can be adjusted down a full size.

Finding the right hat for your face shape is also essential, but what's more important is you pick the style of hat that fits you so that you can wear it confidently.
