Shoulder to Waist Ratio Calculator
Calculate shoulder-to-waist ratio (SWR) from circumference measurements and compare your result with practical taper categories.
Visible shoulder dominance relative to waist size.
| Range | Category |
|---|---|
| 0-1.3 | Lower Taper |
| 1.3-1.45 | Balanced |
| 1.45-1.6 | Athletic Taper |
| 1.6+ | Pronounced Taper |
Shoulder-to-Waist Ratio Interpretation
The highlighted range shows your current shoulder-to-waist taper category.
| RANGE | CATEGORY |
|---|---|
| 0-1.30 | Lower Taper Shoulder-to-waist taper appears lower in this range. |
| 1.30-1.45 | Balanced Balanced shoulder-to-waist proportion range. |
| 1.45-1.60 | Athletic Taper Visible shoulder dominance relative to waist size. |
| 1.60+ | Pronounced Taper Strong V-taper profile from circumference ratio. |
What This Shoulder to Waist Ratio Calculator Measures
Shoulder-to-waist ratio divides shoulder circumference by waist circumference. It is a proportionality metric used to describe visible taper from upper torso to waist.
How to Measure for Better Consistency
- Measure shoulders around the widest point of the deltoid circumference.
- Measure waist at a consistent location, commonly near navel level.
- Keep tape horizontal and snug without compressing skin.
- Repeat each measurement 2 to 3 times and average results.
How to Use Shoulder-to-Waist Ratio
Use SWR as a trend metric for physique proportion goals. It does not diagnose health risk by itself, so combine with waist-centered health screeners and body-composition tools.
For central-fat screening, use the Waist to Height Ratio Calculator and Waist to Hip Ratio Calculator. For frame and shape context, compare with the Body Shape Calculator and Body Frame Size Calculator.
