How to Use This Fitted Baseball Hat Sizes (New Era) Size Chart

Step-by-Step Guide

  1. Measure Your Head: Use a soft measuring tape to measure the circumference of your head, about 1 inch (2.5 cm) above your eyebrows and ears, where the hat will sit.
  2. Find Your Measurement: Look up your head circumference (in inches or centimeters) in the chart above to find your corresponding hat size.
  3. Convert to Your Target System: Once you know your size in one system (e.g., US Fitted), you can easily find the equivalent in other systems (UK Fitted, EU) using the same row in the chart.
  4. Consider Hat Style: Different hat styles fit differently. Structured hats like fitted baseball caps require precise sizing, while flexible hats can accommodate a wider range.

Important Tips

  • Measure at the Right Time: Head size can vary slightly throughout the day. Measure when your hair is in its normal state for the most accurate size.
  • Account for Hair: If you have thick or long hair, you may need to adjust your size slightly. Consider how you'll typically wear your hair with the hat.
  • Size Up When in Doubt: For rigid hats, it's better to size up slightly for comfort. A slightly loose hat can be adjusted with sizer tape, but a too-tight hat is usually unwearable.
  • Check Brand-Specific Charts: Some brands may have slight variations in sizing. Always check the brand's official size chart when available for the most accurate fit.

How to Read This Chart

US Alpha: The common letter-based sizing (S, M, L) used in the United States.

US Fitted: A precise sizing system based on head circumference in inches, famously used by brands like New Era. Represented as a fraction (e.g., 7 1/4).

UK Fitted: Similar to US Fitted but with slightly different values. Also represented as a fraction.

EU: The standard European size, which usually corresponds directly to the head circumference in centimeters.

Head (in/cm): The raw measurement of your head's circumference in inches and centimeters, which is the foundation for all other sizes.

Frequently Asked Questions

How do I measure my head for a hat?

Use a soft measuring tape to measure the circumference of your head, about 1 inch (2.5 cm) above your eyebrows and ears, where the hat will sit. Make sure the tape is level and snug but not tight. If you don't have a measuring tape, use a string and then measure the string with a ruler.

What if my measurement is between two sizes?

For most hats, especially those made of rigid materials, we recommend going up to the next size for comfort. A slightly loose hat is often wearable (and can be adjusted with sizer tape), whereas a hat that's too tight is usually unwearable.

Are these charts universal for all brands?

These charts are based on industry standards and provide a very reliable starting point. However, sizing can vary slightly between brands. If you're buying an expensive or final-sale item, it's always best to check the manufacturer's specific size guide if possible.
