How to Measure

Use a soft tape measure against your body, not over bulky clothing. Stand relaxed and keep the tape level — snug, not tight.

1
Chest — for Men's / Unisex jerseys
Wrap the tape under your arms and across the fullest part of your chest, level around your back. Breathe normally.
2
Bust — for Women's jerseys
Measure around the fullest part of your bust with arms relaxed at your sides. Wear a normal bra for accuracy.
3
Youth — go by age
Kids' sizes are age-based. If your child is between age bands or on the taller side, take the larger size.

Youth — By Age

AGES 8 – 15

Kids' jerseys sized by age group. When in doubt, size up — young fans grow fast and a looser fit lasts more than one season.

Size Recommended Age Best for
S8 – 10 yearsTrue to age
M10 – 12 yearsTrue to age
L12 – 13 yearsTrue to age
XL13 – 15 yearsTrue to age
📈 Size up if…
  • You plan to layer a hoodie or tee underneath
  • You like a loose, authentic ballpark drape
  • You're between two chest/bust ranges
🎯 Stay true if…
  • You want a snug, athletic on-field silhouette
  • You'll wear it mostly over a single layer in warm weather
  • Your measurement sits comfortably mid-range

Size & Fit FAQ

Which table should I use — Chest or Bust?

Open the size options on the product page: men's / unisex jerseys follow the Chest table, women's jerseys follow the Bust table, and kids' jerseys are sized by age. If a product only offers one set of sizes, that's the one to use.

I'm between two sizes. What do I do?

Take the larger size for a relaxed, layer-friendly fit — that's how most fans wear their jerseys. Take the smaller size only if you prefer a close, athletic fit.

Do these jerseys run true to size?

Yes — they follow standard athletic sizing. Match your actual chest/bust measurement to the chart rather than relying on your t-shirt size, since brands vary.

How do I measure my chest correctly?

Keep the tape level all the way around, under your arms and across the fullest part of your chest. Don't pull tight — the tape should sit snug against your body without compressing it.

What if the size I ordered doesn't fit?

Unworn items with tags attached can be exchanged for a different size within our return window. Reach out with your order number and we'll sort you out.

Are youth sizes the same as small adult sizes?

No — youth jerseys are cut proportionally smaller for kids, not just shorter. Use the age-based youth table for children rather than converting to adult sizes.
