# STEP-BY-STEP GUIDE: HOW TO USE THE 39THIRTY HAT SIZE CHART
Here’s my proven 5-step guide to get a perfect fit using the 39thirty hat size chart:
STEP 1: Grab a soft measuring tape. Wrap it around your head, just above your eyebrows and ears—the widest part.
STEP 2: Take the measurement in inches and centimeters. Double-check for accuracy.
STEP 3: Match your measurement to the 39thirty chart below:
– Small/Medium: 21 ¼”–22 ⅜” (54–57cm)
– Medium/Large: 22 ¾”–23 ⅞” (58–60cm)
– Large/X-Large: 24”–25” (61–63cm)
STEP 4: If you’re on the edge between sizes, consider your hair volume. More hair often means sizing up.
STEP 5: Try the cap on (if possible) before removing tags. If shopping online, verify the retailer’s return policy for sizing.
# CASE STUDY: WHY SIZING PRECISION MATTERS
From my experience managing an online hat store, fit complaints dropped by 40% once we gave buyers detailed charts. Jason, a frequent customer, kept ordering Medium/Large because it sounded “safe,” but at 22” circumference, Small/Medium fit him spot-on. That switch alone turned him into a fan—and he spread the word.
# COMMON SIZING MYTHS AND MISTAKES WITH THE 39THIRTY HAT SIZE CHART
Here’s where people go wrong:
1. Assuming all New Era caps fit identically.
2. Only using fitted hat sizes for stretch-fit caps.
3. Ignoring seasonal factors (cold weather or thick hair).
4. Measuring too loosely or too tightly.
# WARNING: DON’T FALL FOR THESE SIZING MISTAKES
Most sizing errors come from NOT following measurement guidelines, or from mixing up sizing between 39thirty and non-stretch hats. If you size based on fitted cap measurements, your 39thirty may feel way too tight or annoyingly loose. Take 2 minutes for proper measurement before you buy—trust me, it beats a month of discomfort.
# PRACTICAL FAQS: EXPERT ANSWERS TO FIT QUESTIONS
**Q: DOES THE 39THIRTY HAT SIZE CHART VARY BY STYLE?**
Generally, the chart stays the same, but very thick or premium weave fabrics can affect stretch slightly.
**Q: CAN WASHING SHRINK A 39THIRTY HAT?**
New Era’s synthetic blends resist shrinkage, but repeated hot washes may cause minor changes.
**Q: IS HEAD SHAPE IMPORTANT?**
Absolutely. Round heads may need more flexibility than elongated heads. Always measure.
# FINAL CHECKLIST FOR THE PERFECT 39THIRTY FIT
Measure your head above eyebrows/ears
Check the 39thirty chart – Small/Medium, Medium/Large, Large/X-Large
Account for hairstyle and head shape
Review retailer’s return/exchange policy before buying
If unsure, visit a store for in-person try-on
# CONCLUSION: YOUR SIZE, YOUR STYLE

With the accurate 39thirty hat size chart, a little measuring, and an eye on the details, you can find the perfect cap every time.
