If you’ve ever measured your head, seen a number like 58 cm, and then wondered whether that means 7 1/4, 7 3/8, or something else entirely, you’re not alone. Western hat sizing can feel confusing, especially when different brands use fractional US sizes, metric measurements, and varying fit profiles.
This guide simplifies the process. You’ll learn how to use a western hat size chart, convert inches to centimeters, understand US hat sizes, and choose a comfortable fit for your head shape and hat style. Whether you’re buying your first cowboy hat or upgrading to a premium felt hat, this guide will help you find the right size with confidence.
Quick Western Hat Size Conversion Cheat Sheet
Finding your western hat size is easier than most people think. Every standard US hat size is derived from the circumference of your head using a simple mathematical principle. Traditionally, hat makers measure the circumference of the head and then divide that measurement by pi (π), approximately 3.1416, to determine the corresponding hat size.
The formula looks like this:
Hat Size = Head Circumference (in inches) ÷ π
For example, if your head measures 22 inches around:
22 ÷ 3.1416 = 7.0
This corresponds to a US hat size 7.
Similarly, if your head circumference is 22¾ inches:
22.75 ÷ 3.1416 = 7.24
Rounded to the nearest standard hat size, this becomes 7¼.
Four Simple Steps
● Measure your head using a flexible tape measure.
● Find your head circumference in inches or centimeters.
● Convert the measurement to a US hat size using the formula or chart.
● Choose your western hat with confidence.
Common Size Conversions
Using the traditional hat sizing formula:
● 22 inches = Size 7
● 22⅜ inches = Size 7⅛
● 22¾ inches = Size 7¼
● 23⅛ inches = Size 7⅜
● 23½ inches = Size 7½
● 23⅞ inches = Size 7⅝
While understanding the formula is helpful, most modern hat manufacturers use standardized sizing charts that perform these calculations for you. Instead of dividing by pi every time, you can simply match your head measurement to the corresponding size in the western hat size chart below.
If you already know your measurement in inches or centimeters, jump straight to the chart below and find your size in seconds.
Cowboy Hat Size Calculator
Not sure what cowboy hat size you need?
Use this simple formula:
Head Circumference (in inches) ÷ 3.14 = Approximate Hat Size
For example:
- 22 inches ÷ 3.14 = 7.0
- Recommended hat size: Size 7
For the most accurate fit, measure your head about 1/8 inch above your ears and across the center of your forehead using a flexible measuring tape.

Although each brand follows standard Western hat sizing chart guidelines, their measurements may vary slightly by manufacturer and fit profile.
What Size Is 58 Centimeters?
One of the most searched questions online is:
“What is a 58 centimeters hat size?”
A head measurement of 58 cm sits between:
- Size 7 1/4 (57.7 cm)
- Size 7 3/8 (58.7 cm)
Most hat experts recommend trying 7 3/8 first if:
- You have a round head shape
- You prefer a relaxed fit
- You’re buying a straw hat
You may prefer 7 1/4 if:
- You have a long oval head shape
- You like a snug fit
- The brand runs large
This is why two people with the same measurement can sometimes wear different sizes comfortably.
How to Measure Your Head for a Western Hat
Before using any US hat size chart, you need an accurate measurement.
What You’ll Need
- Soft measuring tape
- String and ruler (if you don’t have tape)
- Mirror or a helper
Step 1: Position the Tape Correctly
Wrap the tape measure around your head:
- About 1 inch above your eyebrows
- Slightly above your ears
- Around the widest part of the back of your head
This is where your western hat will naturally sit.
Step 2: Keep It Snug
The tape should feel firm but not tight.
A good rule is to leave enough room to slide a finger comfortably underneath. This prevents buying a hat that feels like a vise after an hour outdoors.
Step 3: Measure More Than Once
Take two or three measurements.
If you get slightly different results, use the largest consistent measurement. Small differences can affect your hat size.
Example Measurement
If your head measures:
22 3/4 inches
Your corresponding size is:
7 1/4 (57.7 cm)
That measurement is one of the most common western hat sizes sold today.
For a step-by-step demonstration of how to measure your hat size, watch the YouTube video below.
Common Hat Measurement Mistakes
Many sizing problems start before the hat is even purchased.
Measuring Too High
If the tape sits high on your forehead, you’ll get a smaller measurement than your actual size.
Measuring Hair Instead of Head
Large hairstyles, buns, or thick hair can affect results. Measure your head as you plan to wear the hat.
Pulling the Tape Too Tight
A tight measurement usually leads to an uncomfortable hat.
Measuring Only Once
Human heads aren’t perfectly symmetrical. Multiple measurements improve accuracy.
Why Western Hat Sizes Vary by Brand
Many buyers assume a size 7 1/4 fits exactly the same across every brand.
Unfortunately, that’s not always true.
Oval vs Round Hat Blocks
Hat makers build hats using different block shapes.
Long Oval
Designed for heads that are longer front-to-back.
Round Oval
Designed for heads with a more balanced shape.
A hat can match your circumference perfectly but still feel uncomfortable if the shape doesn’t match your head.
Crown Depth
Some western hats feature deeper crowns than others.
A deeper crown can feel roomier even when the official size remains the same.
Sweatbands and Internal Construction
Leather sweatbands, foam inserts, and sizing tape can affect fit by several millimeters.
Material Differences
Different materials behave differently over time:
Felt Hats
- Can stretch slightly
- Can be professionally reshaped
Straw Hats
- Usually fit tighter initially
- Offer less flexibility
Leather Hats
- May soften and conform to your head with wear
These factors explain why a 58 cm head might wear a 7 1/4 in one brand and a 7 3/8 in another.
Converting Inches to Centimeters
The easiest conversion formula is:
cm=inches×2.54cm=inches\times2.54cm=inches×2.54
Example
22.75 inches × 2.54 = 57.7 cm
That’s why:
7 1/4 hat size = 22 3/4 inches = 57.7 cm
Many websites still repeat outdated explanations involving dividing by pi. Modern western hat sizing relies on established size charts rather than those simplified formulas. The conversion table above remains the most accurate method for finding your size.
Understanding Western Hat Fit Types
The right size is only part of the equation.
Fit profile matters too.
Standard Fit
The most common option.
Works for most wearers and everyday use.
Slim or Long Oval Fit
Better for narrow head shapes.
Reduces side pressure.
Deep Fit
Provides additional crown depth and stability.
Popular among riders and outdoor workers.
What If You’re Between Sizes?
Many people fall between two sizes.
Here are practical solutions:
Size Up and Use Hat Pads
Hat pads can reduce interior space by approximately 3–6 mm.
Use Sizing Tape
Affordable and easy to install.
Professional Stretching
A hat stretcher can increase fit slightly without damaging quality felt hats.
Consider Your Intended Use
- Rodeo riding → Slightly snug
- Windy conditions → Slightly snug
- Casual wear → Slightly relaxed
A small adjustment often creates a perfect fit.
