The Ultimate Fitted Cap Size Chart Guide:

Fitted caps have long been a staple of fashion, sports culture, and personal style. The fitted cap is a versatile and timeless accessory from Major League Baseball (MLB) teams to streetwear brands. However, one of the biggest challenges people face when purchasing a fitted cap is choosing the right size. With so many options available, selecting the perfect fit can be overwhelming. This guide will take you through everything you need to know about fitted cap sizes, how to measure your head, and the best tips for finding the perfect fit.

Understanding Fitted Cap Sizing:

Fitted caps are unique in that they come in specific sizes, unlike adjustable caps with straps or buckles to modify the fit. Fitted caps use a numeric sizing system, typically measured in inches or centimeters, and these measurements refer to the circumference of the head. Common sizes for fitted caps include S (small), M (medium), L (large), and XL (extra-large), but the actual size is more precise, often ranging from 6 3/4 to 8 (inches).

Why Fitted Caps Are Different:

Fitted caps are designed to fit snugly against your head without the option of adjusting. This is why getting the right size is so important. The snug fit is comfortable and keeps the cap in place whether you’re running, playing sports, or just walking around.

Unlike snapbacks or strapback caps, which can be adjusted in size, fitted caps come in several predetermined sizes. The best way to find your size is to accurately measure your head’s circumference.

How to Measure Your Head for a Fitted Cap:

Before diving into the size chart, let’s start with how to measure your head. You’ll need a flexible tape measure (preferably in inches, though centimeters work too). Here’s a step-by-step guide to measuring your head for the perfect fitted cap:

Find the Right Spot:

Place the tape measure around your head, positioning it just above your ears and eyebrows. This is the widest part of your head.

 

Measure Comfortably:

Make sure the tape is snug but not tight. The tape should lie flat against your skin without pulling or compressing the flesh.

Check the Measurement:

Once the tape is in place, look at the number where the tape meets. This is your head circumference.
Record the measurement in either inches or centimeters. This is the number you’ll use to find your fitted cap size.

Fitted Cap Size Chart:

Now that you’ve measured your head, it’s time to find the right size based on your head circumference. Here’s a general fitted cap size chart that corresponds to different head measurements:

Head Circumference Cap Size (Inches) Cap Size (Hat Size)
20 1/4″ – 20 5/8″ 6 3/4″ Small
20 7/8″ – 21 1/4″ 6 7/8″ Small
21 1/2″ – 21 7/8″ 7″ Medium
22″ – 22 3/8″ 7 1/8″ Medium
22 1/2″ – 22 7/8″ 7 1/4″ Medium
23″ – 23 1/4″ 7 3/8″ Large
23 1/2″ – 23 7/8″ 7 1/2″ Large
24″ – 24 3/8″ 7 5/8″ Large
24 1/2″ – 24 7/8″ 7 3/4″ X-Large
25″ – 25 3/8″ 7 7/8″ X-Large
25 1/2″ – 25 7/8″ 8″ XX-Large

Explanation of the Chart:

The first column represents the circumference of your head in inches. The second column represents the corresponding cap size in inches, which is the measurement around the inner band of the cap. The third column represents the general hat size (small, medium, large, extra-large) for each measurement range.

Thus, if your circumference measures 21 1/2 inches, for example, that puts you into the “7,” which is what people would say fits the size of a medium hat. If the head measures a3, you are wearing a “7 3/8” cap large size.

Changing Units: Centimeters to Inches and Vice Versa:

If you happen to be using a metric measurement, don’t worry—you can still use the size chart. Here’s how to convert inches to centimeters:

1 inch = 2.54 cm

To convert your head circumference measurement from inches to centimeters, simply multiply your head circumference (in inches) by 2.54.

For example:

If your head circumference is 22 inches, you would multiply 22 by 2.54, which equals 55.88 cm.
To convert a fitted cap size from centimeters to inches, divide the measurement by 2.54.
Tips for Finding the Right Fit
Choosing the right size can sometimes be tricky, especially if you’re between sizes or if you’re purchasing online without trying the cap on first. Here are some tips to ensure that you find the best-fitted cap for your head:

1. Try It On First

Whenever possible, try the cap on before buying it. Most stores that sell fitted caps allow you to test the cap size in person. This is the most accurate way to determine if the cap fits comfortably.

2. Consider Cap Brands and Styles

Different brands may have slight variations in their sizing. While one brand’s “7 1/4” might fit perfectly, another may feel a bit tighter or looser. Check the manufacturer’s size guide for more specific measurements for the brand you’re considering.

3. Account for Stretch

Fitted caps are made of materials like wool or cotton that tend to stretch over time. Some caps will mold to the shape of your head as you wear them. If you’re between sizes, opting for a slightly tighter cap can be a good idea, as it will naturally loosen up after wear.

4. Don’t Forget About the Fit

Fitted caps come in a variety of crown heights and brim styles. Make sure that the height of the crown fits comfortably on your head and that the brim is positioned correctly to avoid discomfort.

5. Use a Size Conversion Chart for Specific Brands

Always refer to the size chart of that brand if you are purchasing a fitted cap from a brand like New Era, Mitchell & Ness, or Nike. These brands will generally provide more detailed sizing, especially on those types of caps like sports team specialty caps or limited edition releases.
