When a workwear program deploys across multiple regions, fit complaints concentrate in the first month — 90% of them traceable to the size run not matching the regional body distribution. The fabric, color and decoration are perfect; the fit is wrong. This guide is the size-run planning checklist we use with multinational uniform program buyers.
Body measurement baselines by region
Average chest circumference for an adult male, by region (workwear-relevant population, NHANES / WHO data approximated):
| Region | Mean chest (cm) | Implication for size run |
|---|---|---|
| North America | 108-112 | Skew toward L/XL/XXL; carry up to 5XL |
| Europe (Western) | 103-108 | Centered M/L; carry up to 4XL |
| Latin America | 100-105 | Centered M/L; less need for XXXL+ |
| East Asia (China, Japan, Korea) | 92-98 | Skew toward S/M; XXL is the outlier |
| South Asia (India, Pakistan) | 94-100 | Centered M/L; very low demand for XXL+ |
Regional fit philosophy differences
- US fit: Generous through chest and shoulders, longer body length. 'L' chest = 56-58cm flat
- EU fit: Closer through waist, slightly shorter body. 'L' chest = 54-56cm flat
- Asian fit: Closer overall, shorter sleeves. 'L' chest = 50-52cm flat (often equivalent to EU M)
- Universal fit: Compromise sizing that fits 'most people most regions' but fits 'no region perfectly' — used for global uniform programs by major logistics companies
Size run planning by program type
Three approaches to multi-region size runs:
- Single global size run with regional distribution shift: One spec, one set of sizes (XS-5XL). Different region warehouses get different distributions (more L/XL/XXL to NA, more S/M to APAC).
- Regional fit blocks: Same garment design, different fit blocks for NA / EU / APAC. Three separate POs, three separate spec sheets. Highest cost but best fit.
- Universal fit + add-on regional sizes: Universal fit base spec + add regional extreme sizes (US 4XL/5XL, APAC XS in slim cut).
Recommended starting distribution for a typical workwear program
| Size | North America | Europe | Asia |
|---|---|---|---|
| XS | 2% | 3% | 8% |
| S | 8% | 12% | 22% |
| M | 18% | 25% | 32% |
| L | 26% | 27% | 22% |
| XL | 22% | 18% | 10% |
| XXL | 14% | 9% | 4% |
| XXXL+ | 10% | 6% | 2% |
After the first cycle, replace these starting percentages with your actual deployed distribution from inventory data. The pattern stabilizes by month 6 and becomes the reorder baseline.
