Jacket Size Calculator
Measure your chest, height, and hips to estimate a jacket size that matches the closest chart row.
The calculator uses different fit rules for men and women so the result stays closer to how jackets are actually sized.

Run the calculation to see the closest chart match.
Quick Answer
Men's jacket sizes usually lean on chest and height, while women's jacket sizes usually use chest and hips. If you are between two sizes, pick the larger one.
How to Calculate Jacket Size
- Measure your body with a soft tape measure.
- Select the fit type that matches the jacket label.
- Compare your measurements to the closest chart row.
- Choose the larger size if you are between two rows.
Formula
Jacket size = closest chart match based on chest, height, and hip measurements
The calculator looks for the best fit row rather than forcing a single arithmetic formula.
Worked Examples
Example 1: A 68 in height and 38 in chest men's fit lands around M.
Example 2: A 36 in bust and 40 in hips women's fit lands around S or M, so the larger size is safer.
Example 3: A 72 in chest/height combination usually pushes the result toward the bigger chart row.
How to Interpret Your Results
| Output | Meaning | Action |
|---|---|---|
| Exact chart match | Your measurements fit a single row cleanly. | Use that size first. |
| Borderline result | You are between two chart rows. | Choose the larger size. |
| Very different chest and height rows | One measurement suggests a different fit than the other. | Prioritize the larger measurement for comfort. |
