Youth Football Apparel Sizing Guide for Custom Shirts and Hoodies
- Youth football apparel sizing varies by brand: Sport-Tek, Bear Grips, Bella+Canvas, and Gildan each use slightly different measurements.
- Youth sizes (YXS, YS, YM, YL) cover approximately ages 6-14 depending on the child's build.
- Adult XS and S often fit older teen players better than youth XL.
- Coaches should share the specific brand size chart when sending shop links to parents.
Youth football apparel sizing is one of the most common sources of confusion when ordering custom shirts and hoodies for young players. Youth sizes, junior sizes, and adult XS all overlap in ways that differ by brand. Here is a practical guide for coaches and program directors who want to get sizing right the first time.
Youth vs Junior vs Adult Sizing in Football Apparel
The three sizing systems in youth football apparel each target a different body type:
- Youth sizing (YXS, YS, YM, YL, YXL) - Cut for children ages 6-14 with narrower shoulders and a shorter torso. Most common for 8U and 10U programs.
- Junior sizing - An intermediate cut between youth and adult. Narrower in the shoulder than adult S/M but longer in the torso than youth sizing. Less commonly used in athletic apparel. Most "junior vs youth football" confusion comes from comparing football pants sizing (which is different from apparel sizing).
- Adult sizing (XS, S, M, L, XL, 2XL, 3XL) - Standard adult dimensions. For 12U and 14U players, adult S and M often fit better than youth XL, especially across the shoulders for linemen.
Brand-by-Brand Youth Football Apparel Sizing
Sizing measurements vary by brand. Here is what to expect across the most common youth football apparel brands in the Bear Grips catalog:
| Brand | Youth Sizes Available | Runs |
|---|---|---|
| Sport-Tek Youth Tee | YXS-YXL | True to size |
| Sport-Tek Youth Long Sleeve | YXS-YXL | True to size |
| Gildan Youth Hoodie | YS-YXL | Slightly generous |
| Bear Grips Youth Athletic Tee | YXS-YXL | True to size |
| Bella+Canvas Women's Tee (mom shirts) | XS-3XL (adult) | Fitted, size up |
When in doubt about fit, recommend parents size up by one. An XL youth shirt worn slightly loose is far better than a YM that is too tight after the first wash.
Sizing Custom Shirts for Different Youth Football Player Types
Youth football teams include a wide range of body types even within the same age bracket. Practical guidance:
- Skill position players (QB, WR, DB) - Typically run true to size in youth sizing. Youth M or L fits most 10-12 year-old players in these positions.
- Linemen at 10U-12U - Often exceed youth XL dimensions. Adult S or M may be a better fit, particularly for the chest and shoulder measurement.
- Mixed-age programs - If your shop serves a league with 8U through 14U players, stock both youth and adult sizing variants of the same shirt to cover the full range.
In a print-on-demand shop, stocking both sizing systems costs nothing. Each buyer picks their own size and the shirt is produced to that order. There is no pre-buy risk in offering wide size ranges.
How to Communicate Sizing to Football Families When Sharing Your Shop Link
A quick size guidance note alongside your shop link dramatically reduces returns, exchanges, and parent frustration. A simple message that works:
"Shirts are printed on [Brand] [Style]. Check the size chart on the product page before ordering. If your player is between sizes, we recommend sizing up. Linemen and bigger players may fit better in adult sizing (XS or S) than youth XL."
Most parents will reference the size chart when they know it is there. The ones who miss it are usually ordering fast on a phone. A single reminder tip in your first shop announcement reduces the most common sizing issue by roughly half.

Get Started FreeFrequently Asked Questions
What is the difference between youth and junior football sizing?
In apparel, youth sizing (YXS through YXL) is cut for children with narrower shoulders and a shorter torso. "Junior" sizing in youth football more commonly refers to football equipment sizing (helmets, shoulder pads) rather than apparel. For shirts and hoodies, most catalogs use either youth or adult sizing with no separate junior category.
What size football jersey do youth players wear?
For custom printed athletic tees and practice shirts (not cut-and-sew jerseys), youth M and L fit most players aged 8-12. Players 13 and older often prefer adult S or M for a better shoulder fit. Always reference the specific brand size chart before ordering.
How do I know what jersey size a youth football player needs?
Chest measurement is the most reliable starting point. For youth athletic tees, a 28-30 inch chest corresponds roughly to Youth M, 30-32 inches to Youth L, and 32-34 inches to Youth XL. Adult XS covers a 34-36 inch chest for larger youth players.
