Pants Size by Waist Inches
Match the measured waist in inches to the nearest table row.
| Waist | Men's US waist label | Men's EU example | Women's US example range | Women's EU example range |
|---|---|---|---|---|
| 28 in | 28 | 42 | 4–8 | 36–40 |
| 30 in | 30 | 44 | 8–10 | 40–42 |
| 32 in | 32 | 46 | 10–14 | 42–46 |
| 34 in | 34 | 50 | 14–16 | 44–48 |
| 36 in | 36 | 52 | 16–20 | 48–50+ |
| 38 in | 38 | 54 | 18–20 / plus varies | 50+ |
| 40 in | 40 | 56 | plus / brand-specific | brand-specific |
Example: where does a 31-inch waist fall?
The chart shows 30-inch and 32-inch waist rows, not a dedicated 31-inch row. A 31-inch measurement is 78.74 cm, between those two references. Compare both rows instead of automatically calling it a size 31 in every brand.
The 30-inch row shows men's waist 30 and women's US 8–10, while 32 inches shows men's 32 and women's US 10–14. These are chart examples, not a promise that either women's size fits a 31-inch waist.
Keep the inches measurement tied to the waistband position
Take the tape measurement where this particular pair of pants will sit. Measuring a natural waist for low-rise pants can put you on the wrong reference row.
If the product chart gives centimeters, convert your actual inches once (inches × 2.54); then use the retailer's waist and hip ranges rather than rounding the body measurement to a generic label.
