Nothing ruins game day faster than a jersey that rides up like a crop top or drapes like a poncho. Use this quick-reference jersey size chart to nail your fit the first time.
Step 1: Take Three Measurements
1. Chest: Wrap the tape around the fullest part, keeping it level under your arms.
3. Hip (optional for tapered fits): Stand feet together and measure the widest part.
Step 2: Match Your Numbers

XS: 34–36 chest, 27 length
S: 36–38 chest, 28 length
M: 38–40 chest, 29 length

Step 3: Adjust for Fit Preference
– Game-day layer: go one size up.
– Tailored look: choose the smaller size if you’re between sizes.
– Authentic vs. Replica: authentics run 1–2 inches tighter; size up.
Step 4: Double-Check Brand Variance
Nike® NBA Swingman: runs slim—size up for comfort.
Majestic® MLB Cool Base: true to chart.
Pro Tip: Jerseys shrink about ½ inch vertically after the first hot wash; account for this if you plan to machine-dry.
Print this chart, stick it in your wallet, and you’ll never second-guess your jersey size again.
