The VBS shirt sizing problem looks easy until you actually do it. Camper rosters often dont list shirt size, parents underestimate when asked, and the kids who walk up Monday morning need a shirt by 9 AM. Below is the realistic sizing guide for VBS programs of any size, how to estimate the size distribution from camper age data alone, and how much extra to order in which sizes.
| Size | Age range | Typical chest (inches) |
|---|---|---|
| Youth XS | 4-5 | 26-27 |
| Youth S | 6-7 | 28-29 |
| Youth M | 8-9 | 30-31 |
| Youth L | 10-11 | 32-33 |
| Youth XL | 12-13 | 34-35 |
| Adult S | 14-16 (smaller) | 34-36 |
| Adult M | 14-16 (average to larger) | 38-40 |
Bella+Canvas youth sizing runs slightly slimmer than Gildan youth sizing. If your campers skew husky, size up.
If your camper roster has ages but not sizes, this is a reliable starting distribution for a typical mixed-age VBS (ages 4-12):
| Size | % of total order |
|---|---|
| Youth XS | 10% |
| Youth S | 20% |
| Youth M | 30% |
| Youth L | 25% |
| Youth XL | 10% |
| Adult S/M (older campers + spillover) | 5% |
For a 100-camper program, that means 10 YXS, 20 YS, 30 YM, 25 YL, 10 YXL, 5 adult mix. Adjust if your roster skews younger or older.
