Sports Jersey Size Guide
Sizing for NBA, NFL, NHL, MLB, and soccer jerseys. Replica vs authentic, kids vs adult.
Replica vs Authentic — what's the difference?
Replica / Swingman ($60–120)
Loose fit, polyester mesh, screen-printed numbers, lightweight. Looks great worn casually. Fits like a regular t-shirt — buy your usual size.
Authentic / Pro / Match ($150–350)
Athletic fit (snug, especially in NBA + soccer), heavier mesh, stitched lettering, on-court technology (cooling, perforated). Built for actual play. Size UP 1 for casual wear, true to size for athletic fit.
Heritage / Throwback
Mitchell & Ness specializes in retro NBA/NFL. Sized roughly like replicas. Pricier ($150–250) due to licensing + materials.

Youth NBA/NFL: Small (8), Medium (10–12), Large (14–16), XL (18–20). Soccer kids: by age (5–6Y, 7–8Y, 9–10Y, 11–12Y, 13–14Y). Always check brand chart.
Can I add a custom name + number?
Yes via the official team store or Fanatics. Stitched costs $40–60 extra; printed is $20–30. Takes 1–3 weeks. Not all letters allowed (no profanity, no trademark conflicts).
Are women's jerseys cut differently?
Yes — narrower shoulders, slimmer waist, sometimes shorter length. Available for NBA, NFL, MLB, soccer. Use the women's size chart (different from women's t-shirt sizing).
How do I wash a jersey?
Cold water, gentle cycle, inside-out. Air dry. Stitched names/numbers stay better than printed. Replace velcro patches before washing if removable.
