Junior tennis age division apparel covers the five USTA age groups: 10U (ages 9-10), 12U (ages 11-12), 14U (ages 13-14), 16U (ages 15-16), and 18U (ages 17-18). Each division has its own apparel sizing needs from youth small to adult small or medium. Bear Grips Pro Shops stocks youth and adult sizing in the same store with a single logo across the academy, no minimum on any size.

14U13-14Youth L to adult S
16U15-16Adult S to M
18U17-18Adult M to L

Players grow through divisions, so a 12U player may wear a different size than a 14U player at the same academy. Per-piece printing on our model means no inventory headaches when a player grows mid-season.

Recommended product lineup by age

The same academy lineup works across divisions, with sizing adjusted:

Naming and identity across divisions

Single academy logo carries across all divisions. Optional: add division-specific text on tournament drops ("12U National Team", "16U Sectional Squad"). Helps players identify with their cohort within the academy.

How a coach manages multi-division ordering

One coach or academy director manages the store. Players order their own size based on their division. No batch sizing, no roster file required, no manual sorting at delivery. Each shirt prints individually with that player's size and name.

Outfit Every Junior Tennis Division

Same academy logo, sized appropriately for 10U through 18U. No minimum, per-order printing.

Frequently Asked Questions

Are youth and adult sizes the same per-piece price?

Yes on most styles. Youth wicking tee ($23.88) and adult wicking tee ($23.86) are essentially identical.

Can a player order one size up since they're growing?

Yes. Per-order ordering means each family picks their player's current correct size.

Do you handle 10U sizing well?

Yes. Youth XS (typically ages 6-7) covers younger 10U players. Most styles go Y-XS through Adult 2XL.

Should academy apparel say "10U" or "12U" on the shirt?

Optional. Many academies keep player apparel generic (academy logo only) and add division-specific text on tournament tees only.
