Tracksuit sizing runs differently than everyday shirts and pants. Here's how to actually land the right size.
Start With Two Measurements
- Chest — around the fullest part, under the arms.
- Waist — around your natural waistline.
Size Range Breakdown
| Size | Chest (approx.) | Best for |
|---|---|---|
| XS | 34-36" | Slim/athletic builds |
| S | 36-38" | Slim-regular builds |
| M | 38-40" | Average builds |
| L | 40-42" | Average-larger builds |
| XL | 42-44" | Larger builds |
| 2XL-3XL | 44-50" | Plus-size, more room through chest/shoulders |
| 4XL-6XL | 50"+ | Extended plus-size, full room throughout |
Check the size chart on each product before ordering — browse current men's tracksuits to compare.
Athletic vs. Relaxed Fit Changes the Math
An athletic-cut tracksuit fits noticeably closer than a relaxed-cut set in the same labeled size. Size up for athletic/tapered cuts if you're between sizes.
Common Fit Mistakes
- Sizing the jacket and pants separately when chest/waist land in the same bracket.
- Ignoring sleeve and inseam length, especially for taller or shorter builds.
- Assuming all brands size the same — always check the specific product's chart.
Plus-Size Tracksuit Shopping Notes
Look for articulated shoulder seams and a slightly dropped shoulder, plus ribbed or elasticated waistbands with some give. Our plus size tops range follows the same construction principles if you're sizing a jacket separately.
